Cetiosauriscus is a sauropod dinosaur that lived between 166 and 164 million years ago during the Middle Jurassic in what is now England. The fossil was originally confused with Cetiosaurus, a similar sauropod. [1]

Cetiosauriscus was discovered in May 1898 by clay workers south of Peterborough and east of the Great Northern Railway. Pits in this region expose the fossil-rich sedimentary rocks of the marine Oxford Clay, one of the classic geological formations of British palaeontology.[2]
