The new species: Pannoniasaurus
In the third week of December 2012 Researchers discovered the fossilised bones of new species of mosasaurs in Bakony Hills in Western Hungary. Those fossilised bones are thought as marine animals intially.
The details were presented after the study conducted by Laszlo Makadi of the Hungarian Natural History Museum together with the University of Alberta, Canada colleagues. The new species was called Pannoniasaurus. It was found that this species was larger than T.Rex and also they did not share the same ancestor. Their large size shows them as predators in paleo-environment waters.
