Cetiosauriscus by Moondawg

Cetiosauriscus (meaning "whale-lizard-like" i.e. "Cetiosaurus-like") was a close relative of Diplodocus and lived in the Middle to Late Jurassic Period of England.

It was first named by German palaeontologist Friedrich von Huene, in 1927 and is known from a series of vertebrae from the rear half of the skeleton. It has been estimated that this creature stood 6 metres high and was 15 metres in length, weighing about 9 tonnes.

It may have been preyed on by carnivores such as Megalosaurus and Eustreptospondylus.
