Location : Europe

Cetiosauriscus is a large, long-necked dinosaur found in Europe. Discovered over 100 years ago, there is still a question as to which family of dinosaurs it belongs. This large plant eater could have been related to either the North American Diplodocus or the Asian Mamenchisaurus  Since Europe was about in the middle of these two continents, perhaps it was related to both!

Adding to the mystery of this dinosaur, no skull material has yet been found with any of the five partial skeletons discovered to date. It has gone through several name changes and there are currently four species attributed to the genus, spanning more than 20 million years of the Jurassic. It is expected that it will be studied and possibly reassigned in the future.
