Information. In early 1867, the American army surgeon Theophilus Hunt Turner and the army scout William Comstock explored the rocks around In December 1867 Turner and others from Fort Wallace returned to the site and recovered much of the vertebral column, as well as concretions that contained other bones; the material had a combined weight of 360 kilograms (800 lb).
Il possédait 76 vertèbres cervicales1. The centra became more elongated at the middle of the neck, but became shorter again at the back of the neck, with the length and breadth being about equal at the 61st vertebra, and those of the hindmost vertebrae being broader than long. 46 FT FT. Further back in the front part of the neck, around the 25th vertebra, the lower edge of the articular facets became more concave, and the facet shaped like a quadrate with rounded edges. By the 63rd vertebra, the articular facet was also quadratic in shape with rounded edges, whereas the centra of the hindmost vertebrae had a broad oval outline.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. Elasmosaurus, élasmosaure en français, est un genre éteint de la famille des Plesiosauridae ayant vécu au Crétacé supérieur (Campanien, il y a environ 80,5 millions d'années).
It was given its name that very year – a name which means “ribbon lizard.”Most Elasmosaurus pictures have this animal with its head sticking out of the waves, which paleontologists now know is an impossibility for this animal to have done that. All that is known is that it went extinct about the same time as the dinosaurs – around the time of the K/T extinction event. Elasmosaurus is an extinct plesiosaur which lived approximately 80 to 65 million years ago during the Late Cretaceous Period. This group is not a dinosaur group, but is reptilian and belongs to the family group Plesiosauria. They hunted by swimming near the surface with their head above water. Made by.
The researchers concluded that lateral and vertical arches and shallow S-shaped curves were feasible in contrast to the "The exact function of the neck of elasmosaurids is unknown,In 1869 Cope noted that scales and teeth of six species of fish had been discovered directly beneath the vertebrae of the Although elasmosaurids are commonly found with several gastroliths, Elasmosaurid remains provide some evidence they were preyed upon. Weight. Elasmosaurs were a type of aquatic dinosaur. The pre-and post-The vertebrae that transitioned between the neck and back (or dorsal) vertebrae in the In 1869 Cope also published an article about the fossil reptiles of New Jersey, wherein he described Cope discovered another elasmosaurid skeleton in 1876. That means that it was longer than a North Atlantic right whale (which is about 46 feet long) and weighed as much as 2 Beluga whales. If the turtles’ shells were measured in a straight line the numbers would be somewhat higher) Thus, we can state with relative confidence that, at a minimum, Elasmosaurus weighed between 11.5 and 13 tons… A crest (also termed ridge or keel) ran longitudinally along the side of the neck vertebrae (a feature typical of elasmosaurids), visible from the third to the fifty-fifth vertebrae, at the hind part of the neck.
Elasmosaurus was a large marine reptile with an extremely long neck that lived in the ocean 65 million years ago. The bottom was dominated by large Large fish known to have inhabited the sea include the bony fishes The first specimen was discovered in 1867 near Fort Wallace, Kansas, US, and was sent to the American paleontologist Edward Drinker Cope, who named it E. platyurus in 1868.
It's a fish-eater, not designed for hunting larger prey.
Size and Weight: About 35 feet long and seven tons Diet: Fish, turtles and other reptiles, including dinosaurs Distinguishing Characteristics: Long, sleek body; narrow, well-muscled jaws Elasmosaurus Was Incapable of Raising Its Neck Above the Water Given the enormous size and weight of its neck, paleontologists have concluded that Elasmosaurus was incapable of holding anything more than its tiny head above the water—unless, of course, it happened to be sitting in a shallow pond, in which case it could hold its majestic neck out to its full length.
Elasmosaurus Was Not a Dinosaur.
