Fun Rhomaleosaurus Facts For Kids
Gallery
Rhomaleosaurus is one of the largest marine reptiles among the species of sauropterygia plesiosauria. The fossils of Rhomaleosaurus were found near Yorkshire, England.
The fossil specimen was first kept in the Dublin museum and was described by Alexander Carte and W. H. Bailey as a new species of the genus sauropterygia.
In the later years, Harry G. Seeley studied the specimen and declared it as a new genus Rhomaleosaurus. The name Rhomaleosaurus depicts the meaning 'strong lizard'.
It is a maritime predator that feeds on fishes, and marine animals. It hunted its pillage by their smell, it filled its skull with water by forcing it inside.
This adaptation helped them to hunt their pillage and trace their direction before even seeing them. The life of the lizard predator is described on the basis of the fossil study at the museum.
Pliosaurs have a resemblance to the earlier Nothosauridae, which looked like a crocodile and used all four arms to propel in and out of the water as they were also reptiles.
The remains of the Rhomaleosaurus are now showcased at the natural history museum in London in the British United Kingdom where recently with collaboration with google arts they have resurrected Rhomaleosaurus virtually.
The climate of the Mesozoic era for the sea was recreated in virtual reality so that the visitors of the natural history museum could witness the sea dragon in its original form.

They reproduce by giving birth to young ones and not by laying eggs, just like a plesiosaur. This is evident from the fact that a skeleton of a pregnant Rhomaleosaurus was found.
A juvenile Rhomaleosauridae was found inside an adult's skeleton fossils. Before the finding, scientists believed that the sea dragon was too cumbersome to come outside water to lay eggs, so maybe they gave birth to young ones. The fossils are the first direct evidence of the reproductive manner of the plesiosaurus, according to paleontologist Adam Smith.
