Its habitats were: beaches, plains, forests, mountains, deserts and swamps. It lived in North and South America, Asia, Europe, They lived in the Late Jurassic Period. Australia, Belgium, Spain and England. The name comes from the fact that the Brachiosaur's front legs were longer than its back legs. Most other dinosaurs had back legs that were longer than their front legs or arms.

Oviraptors also used their beaks to tell each other apart with a small crest-like nub that sat on top of their heads.

https://www.nhm.ac.uk/discover/dino- directory/name/a/gallery.html https://www.dinopit.com/ Appearance: Elasmosaurus had four long paddle-like flippers, an extremely long neck topped with a tiny head, and a short tail (typically no longer than the flippers). Its neck accounts for half its total length. They had strong jaws and sharp teeth.

Size: Elasmosaurus could get to 14m long and weighed in at 2,700 kg.

Other: Elasmosaurus was a large marine reptile with an extremely long neck that lived in the ocean 65 million years ago. Elasmosaurus ate small bony fish, squid-like sea creatures, and mollusks so it was a carnivore. The extremely long neck of Elasmosaurus was key to its survival in the ocean and was used for stable balance while swimming in the sea. Elasmosaurus swam slowly using its four paddle-like flippers in a manner similar to that of modern turtles. Contrary to popular misconception, Elasmosaurus (as any Plesiosaur) was not capable of raising its long neck above water, unless it were near a shore and could rest its body upon land.
