mosasaurus vs elasmosaurus

The bullets landing on it created many sparks before falling into the ground. The teeth interlocked, and their tooth crowns were slender and rounded in cross-section. (2013)[74] As none of these elements overlap with those of the holotype specimen, in 2005 the American paleontologist Michael J. Everhart concluded they belonged to the same individual, and that the parts had been separated before burial of the carcass. marshii to a genus of its own, Thalassonomosaurus;[37] however, Carpenter sunk T. marshii into Styxosaurus snowii in 1999. [8], In subsequent years, Elasmosauridae came to be one of three groups in which plesiosaurs were classified, the others being the Pliosauridae and Plesiosauridae (sometimes merged into one group). Turner died unexpectedly at Fort Wallace on July 27, 1869, without seeing the completion of the work he began, but Cope continued to write him, unaware of his death until 1870. At up to 40 feet (12 m) long, Elasmosaurus was among the largest of the long-necked plesiosaurs. Mosasaur Marine Reptile Of Early Cretaceous. The argument was part of the "Bone Wars" rivalry between the two, and is well known in the history of paleontology. [19] A specimen of the closely related Styxosaurus contained fragmented fish bones and stones in the abdominal region behind the pectoral girdle. [15][2], The atlas and axis bone complex, consisting of the first two neck vertebrae and articulated with the back of the skull, was long, low, and horizontally rectangular in side-view. Back vertebrae are not useful for distinguishing between elasmosaurids, since they are not diagnostic at the genus level. [15] In 1986 a three-dimensional reconstruction of the holotype skeleton was completed and is now displayed at the ANSP. It is uncertain how many teeth Elasmosaurus had, due to the fragmentary state of the fossils. [66] Charles Andrews elaborated on differences between elasmosaurids and pliosaurids in 1910 and 1913. Thus, Elasmosaurus would have been unable to swim in one direction while moving its head and neck either horizontally or vertically in a different direction. [32], Carpenter's 1997 phylogenetic analysis of plesiosaurs challenged the traditional subdivision of plesiosaurs based on neck length. On the other hand, bending the neck sideways did increase drag force, more so in forms with very long necks. less specialized) than other elasmosaurids with the exception of Libonectes. gigas. Since its initial assignment to the Elasmosauridae, the relationships of Brancasaurus had been considered well supported, and an elasmosaurid position was recovered by O'Keefe's 2004 analysis[71] and Franziska Großmann's 2007 analysis. [32][33] Per Ove Persson retained it as valid in 1963, noting the longitudinal ridge on the sides of the centra as an elasmosaurid trait. [42] However, in his 1906 revision of North American plesiosaurs, Williston regarded the vertebrae as "all more or less mutilated", and found no distinct differences between the remains of E. intermedius and E. Piscivore The mandibular symphysis (where the two halves of the lower jaw connected) was well ossified, with no visible suture. [22][15] In spite of their many neck vertebrae, the necks of elasmosaurids were less than half as long as those of the longest-necked sauropod dinosaurs. Thus, Elasmosaurus could have raised its head and neck above the water only when in shallow water, where it could rest its body on the bottom. [69], In 1940 Theodore White published a hypothesis on the interrelationships between different plesiosaurian families. However, although the bullets didn’t directly penetrate the mutant Elasmosaurus skin. [24] Another species, E. nobilis, was named by Williston from very large remains discovered by Mudge in 1874 in Jewell County, Kansas. They explained that elements missing from the holotype may have been lost to weathering or simply not collected, and that parts may have been lost or damaged during transportation or preparation. He divided plesiosaurs into two superfamilies, the Plesiosauroidea and Pliosauroidea, based on neck length, head size, ischium length, and the slenderness of the humerus and femur (the propodialia). Elasmosaurus is number 119 of the Carnivore Threes that can be created in Jurassic Park III: Park Builder. A. N. Riabinin described a single phalanx from a flipper in 1915 as E. [94], Elasmosaurus is known from the Sharon Springs Member of the Campanian-age Upper Cretaceous Pierre Shale formation of western Kansas, which dates to about 80.5 million years ago. This is disputed as there would be large hydrostatic pressure differences, particularly for the extremely long-necked elasmosaurids. [51], Two additional Russian species were described by subsequent authors. He considered Elasmosauridae to be closest to the Pliosauridae, noting their relatively narrow coracoids as well as their lack of interclavicles or clavicles. The surface (or facet) where the axis articulated with the next vertebra had an oval outline, and an excavation for the neural canal in the middle of its upper edge. Elasmosaurus is known from the Pierre Shale formation, which represents marine deposits from the Western Interior Seaway. 6460x1481 Elasmosaurus by FeralStormRaptor on DeviantArt. 6.1 Pre-Fight 6.2 FIGHT! Jurassic World: Fallen Kingdom Survival Guide, The Science Of Jurassic Park And The Lost World Or, How To Build A Dinosaur, Jurassic Park III: Park Builder Creatures, Human-Dinosaur Hybrids (Jurassic Park Orlando), https://jurassicpark.fandom.com/wiki/Elasmosaurus?oldid=254377. It probably had six teeth in each premaxilla, and the teeth preserved there were formed like large fangs. [40] Welles moved this specimen to the new genus and species Alzadasaurus riggsi in 1943. Thus, he renamed the species E. snowii. It could swim into schools of fish, moving its head back and forth to catch them. [89] Simulation of water flow on 3D models showed that more elongated necks, such as those of elasmosaurids, did not increase drag force while swimming compared to shorter necked plesiosaurs. [32], Williston named a number of other new Elasmosaurus species in his 1906 revision. [2], The vertebrae that transitioned between the neck and back (or dorsal) vertebrae in the pectoral region of plesiosaurs, close to the front margin of the forelimb girdle, are often termed pectoral vertebrae. of Scania (S.

The vertebrae were, according to Cope, the shortest among members of the genus (approaching Cimoliasaurus in this condition), but he still considered them as belonging to Elasmosaurus due to their compressed form. Elasmosaurus is an Aquatic Carnivorous Creature. [37] Pierre de Saint-Seine in 1955 and Alfred Romer in 1956 both adopted Welles' classification. Cope gave the name orientalis to the new species, on account of it possibly having a more easterly distribution than E. [96], The soft, muddy sea floor probably received very little sunlight, but it teemed with life due to steady rains of organic debris from plankton and other organisms farther up the water column. [30], In the same 1869 publication wherein he named E. platyurus and E. orientalis, Cope assigned an additional species, E. constrictus,[8] based on a partial centrum from a neck vertebra found in the Turonian-aged clay deposits at Steyning, Sussex, in the United Kingdom. Well from looking at the stats it appears that Mosasaurus is better than the plesiosaur in every single way. [75] These genera had all previously been considered to be elasmosaurids by Carpenter, Großmann, and other researchers. Download. Davidson and Everhart concluded that the girdle fossils were most likely destroyed in Hawkins' workshop. 6.3 K.O.! [28], In 1869 Cope also published an article about the fossil reptiles of New Jersey, wherein he described E. orientalis as an animal with a "long neck". [37] Kenneth Carpenter reassigned it to Thalassomedon haningtoni in 1999;[24] Sachs, Johan Lindgren, and Benjamin Kear noted that the remains represented a juvenile and were significantly distorted, and preferred to retain it as a nomen dubium in 2016. The coloring page is printable and can be used in the classroom or at home. The pre-zygapophyses here were shorter than those in the neck and pectoral vertebrae, and only reached above the level of the centrum with the front third of their length. One of these was E. chilensis, based on the Chilean Plesiosaurus chilensis named from a single tail vertebra by Claude Gay in 1848. sachalinensis; the species was named after the island of Sakhalin, where N. N. Tikhonovich found it in 1909. [67][68] Although the placement of Elasmosaurus in the Elasmosauridae remained uncontroversial, opinions on the relationships of the family became variable over subsequent decades. [16] In 1943 Welles moved E. marshii. Although its validity was supported for a considerable time, M. haasti is regarded as a nomen dubium as of 2017. 4"; he excavated it with the help of George B. Cledenning and Capt. It was long exhibited, but is now stored in a cabinet with other assigned fragments. He considered Simolestes a possible ancestor of Elasmosaurus. [2], In 1869 Cope scientifically described and figured Elasmosaurus, and the preprint version of the manuscript contained a reconstruction of the skeleton which he had earlier presented during his report at an ANSP meeting in September 1868. [31] Cope recognized this as a natural condition, and considered constrictus to be "a species of Elasmosaurus or an ally". Nothing was subsequently mentioned about their loss by Hawkins or Cope. [16] While he initially assigned it in 1890 to a new species of Cimoliasaurus, C. snowii,[44] he subsequently recognized the elasmosaurid nature of its humerus and coracoids. Their necks were so long they wouldn't have been able to lift more than its head above the water. [32] Persson noted in a 1959 review of the Swedish "E." helmerseni material that, while the species was probably closely related to Elasmosaurus proper, it was too fragmentary for this hypothesis to be assessed;[47] he later remarked in 1963 that, regarding the latter three species, "their generic and specific definition is questionable", although he declined to specifically label them as invalid on account of not having seen the fossil material. This long neck came in useful for this reptile. The specimen consists of the premaxillae, part of the hind-section of the right maxilla, two maxilla fragments with teeth, the front part of the dentaries, three more jaw fragments, two cranial fragments of indeterminable identity, 72 neck vertebrae, including the atlas and axis, 3 pectoral vertebrae, 6 back vertebrae, 4 sacral vertebrae, 18 tail vertebrae, as well as rib fragments. 11-14 metres (36-46 ft) His diagnosis of the Elasmosauridae also noted the moderate length of the skull (i.e., a mesocephalic skull); the neck ribs having one or two heads; the scapula and coracoid contacting at the midline; the blunted rear outer angle of the coracoid; and the pair of openings (fenestrae) in the scapula–coracoid complex being separated by a narrower bar of bone compared to pliosaurids. [16] He again made reference to a new species of Elasmosaurus, from Kansas, in 1908. In December, LeConte delivered some of the vertebrae to the American paleontologist Edward Drinker Cope at the Academy of Natural Sciences of Philadelphia (ANSP, known since 2011 as the Academy of Natural Sciences of Drexel University). [78] Carpenter's 1999 analysis suggested that Elasmosaurus was more basal (i.e. Reward: 11,280 Food "A relatively slow swimmer, the Elasmosaurus hides itself in the darker depths and uses its long neck to ambush schools of fish." It has a long, thin, slightly arched neck, with a small head and tapered snout with small, narrowed black eyes. In 2002 the American art historian Jane P. Davidson noted that the fact that other scientists early on had pointed out Leidy's error argues against this explanation, adding that Cope was not convinced he had made a mistake. [64] Another species from Russia, E. antiquus, was named by Dubeikovskii and Ochev in 1967[51] from the Kamsko-Vyatsky phosphorite quarry, but Pervushov and colleagues in 1999, followed by Storrs and colleagues in 2000, reinterpreted it as an indeterminate elasmosaurid. It features the Megalodon from the 2018 movie, The Meg, and the Mosasaur from the 2015 movie, Jurassic World. [3], Though Cope described and figured the pectoral and pelvic girdles of Elasmosaurus in 1869 and 1875, these elements were noted as missing from the collection by the American paleontologist Samuel Wendell Williston in 1906. The centra, or "bodies", of these vertebrae were co-ossified in the holotype specimen, which indicates it was an adult. He bore reservations about its referral to the genus, and he recognized that it possibly pertained to another genus. Take your favorite fandoms with you and never miss a beat. [49] However, the validity of all these species has been questioned. [46], Several Russian species, based on poorly preserved vertebral remains, were assigned to Elasmosaurus by N. N. Bogolubov in 1911. Death Battle by I'm Lynda. [60], In 1949 Welles named a new species of Elasmosaurus, E. morgani. [61] In 1997 Carpenter reconsidered the differences between the two species, and found them sufficient to place E. morgani in its own genus, which he named Libonectes. The first of these vertebrae was used as a doorstop in a tailor's shop, whereas the other was found in a pit by Samuel Lockwood, a superintendent. [81][88], Although elasmosaurids are commonly found with several gastroliths, Elamosaurus has only been found uncontroversially with a pebble lodged in the neural arch of one of its hindmost tail-vertebrae. [9][29] In an 1870 reply to Leidy, Cope himself stated that the generic placement of E. orientalis was in doubt, and that he had illustrated it with a short neck due to believing this was the condition of Cimoliasaurus. Persson considered it a valid species, and a relatively large member of the elasmosaurids;[34] however, like E. (?) The centra of the atlas and axis were of equal length, and had a quadratic shape in side view. [16] Welles named E. nobilis as a species of Thalassonomosaurus, T. nobilis, in 1943,[37] but it too was considered to be part of S. snowii by Carpenter. [2] Like other elasmosaurids (and plesiosaurs in general), Elasmosaurus would have had large, paddle-like limbs with very long digits. [74][75][38] Their analysis also moved Muraenosaurus to the Cryptoclididae, and Microcleidus and Occitanosaurus to the Plesiosauridae;[73] Benson and Druckenmiller isolated the latter two in the group Microcleididae in 2014, and considered Occitanosaurus a species of Microcleidus. Elasmosaurus Elasmosaurids were well adapted for aquatic life, and used their flippers for swimming. Cope was only in his late twenties and not formally trained in paleontology, and may have been influenced by Leidy's mistake of reversing the vertebral column of Cimoliasaurus. [17], Fossils that may have belonged to the holotype were found by the American geologist Benjamin Franklin Mudge in 1871, but have probably been lost since. Elasmosaurus vs. Tylosaurus. About Elasmosaurus Vs. Tylosaurus Coloring Page. Some material from Scania, Sweden, was assigned to P. helmerseni in 1885 by H. 2944x1255 Elasmosaurus Skull Images & Pictures - Becuo. Download. Welles considered E. kurskensis as an indeterminate plesiosaur in 1962. Tier: 9-B, higher via piercing damage Name: Mosasaurus Origin: The Real World Gender: Varies Age: Varies Classification: Mosasaur Powers and Abilities: Superhuman Physical Characteristics, Enhanced Senses, Large Size (Type 1), Natural … [73] Benson and Druckenmiller's 2013 analysis (below, left) further removed Terminonatator from this group and placed it as one step more derived. [52] However, this specimen cannot be identified more specifically than an indeterminate elasmosaurid, which was followed by Persson[34] and Pervushov and colleagues. [2] Since the last tail-vertebrae of elasmosaurids were fused into a structure similar to the pygostyle of birds, it is possible this supported a tail-fin, but the shape it would have had is unknown. Mosasaurus Vs Plesiosaur. What type of plants do the mosasaur eat? [34], Welles took issue with White's classification in his 1943 revision of plesiosaurs, noting that White's characteristics are influenced by both preservation and ontogeny. The fish remains were identified as Enchodus and other clupeomorph fish. The Dinosaurs and Prehistoric Animals of Kansas. The paddles at the front (the pectoral paddles) were longer than those at the back (the pelvic paddles). Clam shells would have accumulated over the centuries in layers under the sea floor's surface, and would have provided shelter for small fish. It was named from a well-preserved skeleton found in Dallas County, Texas. sachalinensis, Pervushov and colleagues considered E. amalitskii an indeterminate elasmosaurid. The neural spines of the neck vertebrae appear to have been low, and almost semi-circular by the 20th vertebra. In contrast, Kronosaurus, an Early Cretaceous pliosaur from Australia, grew to about… The eyes of the animal were at the top of the head and allowed them to see directly upward. [41], Subsequently, a series of 19 neck and back vertebrae from the Big Bend region of the Missouri – part of the Pierre Shale formation – were found by John H. Charles. [81] It has also been suggested that the long necks of plesiosaurs served as a snorkel and allowed them to breathe air while the body remained underwater. The post-zygapophyses reached over the level of the centrum with the back half of their length. Also, the weight of the neck, the limited musculature, and the limited movement between the vertebrae would have prevented Elasmosaurus from raising its head and neck very high. [24] In 2005 Sachs suggested that Elasmosaurus was closely related to Styxosaurus,[2] and in 2008 Druckenmiller and Russell placed it as part of a polytomy with two groups, one containing Libonectes and Terminonatator, the other containing Callawayasaurus and Hydrotherosaurus. The snout was rounded and almost formed a semi-circle when viewed from above, and the premaxillae (which form the front of the upper jaw) bore a low keel at the midline. Theodor Wagner had previously assigned gigas to Plesiosaurus in 1914. One was E. helmerseni, which was first described by W. Kiprijanoff in 1882 from Maloje Serdoba, Saratov, as Plesiosaurus helmerseni. [27] In 1952 Welles considered the species a nomen dubium, given how fragmentary it was. Schröder. Data based on these lost elements were unquestionably accepted in subsequent phylogenetic analyses, until a redescription of the surviving elements was published by Sachs and Benjamin Kear in 2015. The Avengers, or any other plethora of battle combinations, paleontology nerds have arguments very similar just for the fun of it. Contrary to earlier depictions, their necks were not very flexible, and could not be held high above the water surface. mosasaur was a strict carnivor. Telesné znaky. Cope had apparently concluded that the tail vertebrae belonged to the neck, since the jaws had been found at that end of the skeleton, even though the opposite end terminated in the axis and atlas bones that are found in the neck. The stones match rock from 600 kilometers (370 mi) away from where the specimen was found. If more remains showed E. orientalis to have had a long neck like Elasmosaurus, he stated the image may instead represent Cimoliasaurus better. Mosasaurus could reach 50 feet long and is estimated to have weighed 15 tons. The type remains were discovered by him in the same 1874 expedition with Mudge. [28] Glenn Storrs considered both to be indeterminate elasmosaurids in 1999;[45] in the same year, Carpenter assigned both to Styxosaurus snowii. The weight of its long neck placed the center of gravity behind the front flippers. In addition, the longer neck would also have increased dead space, and the animals may have required larger lungs. Elasmosaurus is an extinct genus of plesiosaur with an extremely long neck that lived in the Late Cretaceous. Elasmosaurus is one of the most widely recognised plesiosaur names and has become a stereotype for all elasmosaurids. The facets where the neck ribs articulated with the neck vertebrae were placed on the lower sides of the centra, but were only placed higher in the last three vertebrae, reaching around the middle of the sides. Cope sent instructions on how to pack the bones, which were thereafter sent in hay-padded crates on a military wagon east to the railroad, which had not yet reached the fort. The circumstances around Turner's discovery of the type specimen were not covered in Cope's report, and remained unknown until Turner's letters were published in 1987. Elasmosaurids probably ate small bony fish and marine invertebrates, as their small, non-kinetic skulls would have limited the size of the prey they could eat. [58] Pravoslavlev recognized another species from New Zealand, E. hoodii, named by Owen in 1870 as Plesiosaurus hoodii based on a neck vertebra. The upper processes of the shoulder blades were very broad, and the "necks" of the shoulder blades were long. [2][3][16][17] In 2018, Davidson and Everhart documented the events leading up to the disappearance of these fossils, and suggested that a photo and drawing of Waterhouse's workshop from 1869 appear to show concretions on the floor that may have been the unprepared girdles of Elasmosaurus. [84] The paddles of plesiosaurs were so rigid and specialized for swimming that they could not have come on land to lay eggs like sea turtles. Mosasaurus hoffmanni vs. Carcharocles megalodon. [81] Plesiosaurs were even believed to have been able to maintain a constant and high body temperature (homeothermy), allowing for sustained swimming. The dentition of elasmosaurids was generally heterodont (irregular throughout the jaws), with the teeth becoming progressively smaller from front to back. [74] In Rodrigo Otero's 2016 analysis based on a modification of the same dataset (below, right), Elamosaurus was the closest relative of Albertonectes, forming the Styxosaurinae with Styxosaurus and Terminonatator. "Elasmosaurid remains from the Pierre Shale (Upper Cretaceous) of western Kansas. The family Elasmosauridae was based on the genus Elasmosaurus, the first recognized member of this group of long-necked plesiosaurs. [8] In 1962 Welles considered P. constrictus to be a nomen dubium, given its fragmentary nature. Water Dinosaur. The neck ribs were semicircular to quadratic in side view, and were directed rather straight down. Here the rib facets where placed higher than the transverse processes, separating the two, and were oval to rectangular in outline. Therefore, they probably gave live-birth (viviparity) to their young like sea snakes. [86], Cope, in 1869, compared the build and habits of Elasmosaurus with those of a snake. Elasmosaurus was often not used due to its stats and its model. [50], In a 1918 review of the geographic distribution and evolution of Elasmosaurus, Pravoslavlev provisionally assigned three other previously named species to Elasmosaurus;[48] his taxonomic opinions have not been widely followed. The lower part of the centra were rounded from the first to the third tail vertebrae, but concave from the fourth to the 18th. Enjoy! The skull would have been slender and triangular, with large, fang-like teeth at the front, and smaller teeth towards the back. Mosasaurus 3D models ready to view, buy, and download for free. They also noted that conceptual sketches of the Palaeozoic Museum show that the model Elasmosaurus was originally envisioned with a long "tail", though later updated with a long neck. Leidy also concluded that Elasmosaurus was identical to Discosaurus, a plesiosaur he had named in 1851. (?) Yet, in an accompanying illustration Cope showed a short-necked Elasmosaurus confronting a Dryptosaurus (then Laelaps), with a plesiosaur-like Mosasaurus and other animals in the background. Tylosaurus as a Mosasaur Tylosaurus was one of the larger mosasaurs that lived towards the end of the Cretaceous period,‭ ‬something which has secured its frequent inclusion in popular media such as books and television documentaries.‭ ‬Rivals to Tylosaurus in terms of upper size include Mosasaurus and Hainosaurus. The living animal would have been slightly larger due to cartilage present between the vertebral bodies, and was estimated by Cope at roughly 13.7 meters (45 ft). Each superfamily was further subdivided by the number of heads on the ribs, and the proportions of the epipodialia. The number of premaxillary teeth distinguished Elasmosaurus from primitive plesiosauroids and most other elasmosaurids, which usually had fewer. The known teeth of the front part of the lower jaw were large fangs, and the teeth at the back of the jaws appear to have been smaller. [50] Storrs, Arkhangelsky, and Efimov were less specific, labelling it as an indeterminate plesiosaur;[51] this classification was followed by Alexander Averianov and V. K. Popov in 2005. It did breathe air. Recognizing them as the remains of a plesiosaur, larger than any he had seen in Europe, Cope wrote to Turner asking him to deliver the rest of the specimen, at the ANSP's expense. [2], Most of the neck vertebrae were compressed sideways, especially at the middle of the neck. [22][15][2], The neural arches of the neck vertebrae were well fused to the centra, leaving no visible sutures, and the neural canal was narrow in the front vertebrae, becoming more prominently developed in the hind vertebrae, where it was as broad as high, and almost circular. The 20 Biggest Dinosaurs and Prehistoric Reptiles. In May 1871 much of the exhibit material in Hawkins' workshop was destroyed by vandals (working for the New York politician William M. "Boss" Tweed) and their fragments buried; it is possible that the girdle elements of Elasmosaurus were at the workshop and were likewise destroyed. [38] Danielle Serratos, Druckenmiller, and Benson could not resolve the position of Elasmosaurus in 2017, but they noted that Styxosaurinae would be a synonym of Elasmosaurinae if Elasmosaurus did fall within the group. The two teeth at the front were smaller than the succeeding ones, and were located between the first two teeth in the dentaries of the lower jaws. Although he suggested that the vertebral column of the trunk did not allow for much vertical movement due to the elongated neural spines which nearly form a continuous line with little space between adjacent vertebrae, he envisaged the neck and tail to have been much more flexible: "The snake-like head was raised high in the air, or depressed at the will of the animal, now arched swan-like preparatory to a plunge after a fish, now stretched in repose on the water or deflexed in exploring the depths below". The researchers concluded that lateral and vertical arches and shallow S-shaped curves were feasible in contrast to the "swan-like" S-shape neck postures that required more than 360° of vertical flexion. [34] In 1995 Nathalie Bardet and Pascal Godefroit also recognized it as an elasmosaurid, albeit indeterminate. [8], The flexion ranges of Elasmosaurus necks would have allowed the animal to employ a number of hunting methods including "benthic grazing", which would have involved swimming close to the bottom and using the head and neck to dig for prey on the sea floor. (?) Cope had also discovered another large skeleton that bore great resemblance to the known remains of E. orientalis from the black shale of the "Cretaceous bed No. Additional parts of the same skeleton are housed at the Institute for Geology of the University of Hamburg, as well as in private collections. Given that, at the time of Persson's writing, "there [was] nothing to contradict that they are nearest akin to Elasmosaurus", he assigned them to Elasmosaurus "with hesitation".

Mosasaur Pictures and Profiles. Name meaning The neural spine was low and directed upwards and back. Much like the heated debates that plague comic book shops around the world of Batman vs. Superman, Hulk vs. Wolverine, Iron man vs. Batman, the Justice League vs. Only Albertonectes had more neck vertebrae, 75, and the two are the only plesiosaurs with a count higher than 70; more than 60 vertebrae is very derived (or "advanced") for plesiosaurs. The lower part of the neural canal was narrow towards the back by the axis, where it was half the breadth of the centrum. Neck would also have increased dead space, and the teeth preserved there were formed like large.. In 2005 by the Fossil of an adult phylogenetic analysis of plesiosaurs based neck.
