Description: Elasmosaurus is a genus of large, carnivorous dinosaur that lived during the Late Cretaceous Period, about 85-70 million years ago. It was a member of the group of dinosaurs called the plesiosaurs, which includes a diverse group of marine reptiles that are characterized by their long necks, small heads, and large flippers. Elasmosaurus was a large, agile reptile, with an estimated length of about 30-40 feet and a weight of up to 4 tons. It had a long, slender neck, with more than 70 vertebrae, which made up about half of its total body length. It had a small, triangular head with a pair of large, forward-facing eyes and a mouth full of sharp, serrated teeth. It had a streamlined body, with four large, paddle-like flippers and a long, flexible tail. Elasmosaurus is known from a number of well-preserved fossil specimens, including several complete skeletons and skulls, which have helped paleontologists learn more about the anatomy and behavior of this reptile. It is known from North America, and is named after the Greek words 'elasmos', which means 'thin', and 'saurus', which means 'lizard', in reference to its thin, elongated neck. Elasmosaurus was a carnivorous reptile, feeding on a variety of small to medium-sized prey animals. It is considered a primitive plesiosaur, and is thought to be closely related to other members of this group such as Kronosaurus and Liopleurodon. Elasmosaurus is important because it is one of the best-known plesiosaurs, and provides insight into the anatomy and behavior of this group of marine reptiles. It is also significant because it is one of the few known plesiosaurs that is known from well-preserved fossil specimens, and provides important evidence for the evolutionary relationships and diversity of these animals.
