Elasmosaurus it was kind of crawling (A reptile (Latin Reptilia) is a vertebrate, generally…) A sailor of the Elasmosauridae family, 15 meters long and lived in the Cretaceous period. He had 76 cervical vertebrae.

His height was about 14 m. length (The length of an object is the distance between its two farthest ends…) and weighed more than 2,000 kg (2.2 tons). It was due to having a large body and four fin-like limbs, more than half of its length the neck (The neck is the region of the body between the head and the rest of the body…)With more than 70 vertebrae, more everything (The whole, understood as the whole of what exists, is often interpreted as the world or…) else animal (An animal (from Latin animus, spirit or vital principle) according to classical classification, a…). Its head was relatively small compared to its body and it had many teeth.

Like most plesiosaurs, Elasmosaurus was ihe can’t lift his head upwater (Water is a ubiquitous chemical compound on Earth, essential for everyone…)contrary to their depictions in art and the media (We call media non-personal means of disseminating information (press, radio, etc.). the weight (Weight is the force of gravity, derived from gravity and inertia, exerted by …) it replaces it by its long neck Center of gravity (The center of gravity is the point of application of forces resulting from…) behind the front wings. Thus, Elasmosaurus could only raise its head and neck above water when it was in shallow water, where it could keep its body on the bottom. It is likely that a situation (In geography, situation is a concept of space that allows for the relative location of a place…) fatal to the animal. Elasmosaurus probably couldn’t raise its head very high mass (The term mass is used to define two quantities related to one another…) neck and muscles and traffic (Traffic (Anglicism: traffic) is the movement of motor vehicles…) limited between the vertebrae.

The head and neck of Elasmosaurus probably moved whom manages (A control surface is a mobile surface that moves in air or water…) of management. If the animal moved its head and neck in a certain direction, it dragged the rest of the body in that direction. So the elasmosaurus could not swim to the island meaning (SENS (Strategies for Engineered Negligible Senescence) is a scientific project…) and his head and neck are positioned either horizontally or vertically. Elasmosaurus probably ate little Fishes (Pisces is the zodiac sign that the Sun transits on March 12-18…) bone, belemnites (squid-like) and ammonoidea (molluscs). He swallowed small stones (gastrolith) to help himself digestion (Digestion is the process by which a living organism takes in the environment…).

Elasmosaurus is believed to have lived mainly in the erathe ocean (In geography, an ocean is often defined as a large body of water…) It has been open since the Cretaceous period. Elasmosaurus and other plesiosaurs were specialized for swimming and could not come soil (Earth is the third planet in the solar system in order of distance…) to lay eggs. So he must have been giving the young are born directly in the water like a snake the sea (The term sea encompasses several realities.) modern.

When ED Cope received the sample in early March 1868, she had a preconceived idea about her looks and so she put her head on the wrong end spine (The spine or vertebral column is a collection of articulated bones called….). In his defense, he was an expert on lizards with short necks and long tails, and no one had ever seen him. Plesiosauroidea the size of an elasmosaurus.

In fact, Joseph Leidy pointed out the problem in his speech Elasmosaurus platyurus addressedAcademy of Sciences (Academy of Sciences is a learned society whose role is to promote research…) naturally Philadelphia (Philadelphia is a city in Pennsylvania, USA…) during meeting (Reunion is a French island in the southwest Indian Ocean…) On March 8, 1870. OC Marsh did not mention Copen’s error in a newspaper article until 1890, twenty years after Leidy.
