A new dinosaur find from 85 million years ago, in the late Cretaceous Period, Pannoniasaurus inexpectatus, has been discovered in western Hungary.
Pannoniasaurus is described TG Daily as having:
Legs like a terrestrial lizard, a flattened crocodile-like skull, and a tail unlike other known members of the mosasaur family.
The grown crocodile-like creature was some six metres (about 20 feet) in length and was at the top of its food chain. Besides having an unusual tail, it is believed to have been the only Mosasaur that lived in rivers or estuarine environments, rather than the sea. It was also adapted to live in fresh water environments, rather than salt water, as other Mosasaurs did. This similarity also exists in modern crocodilians.
PlosOne, the scientific journal, says scientists have assigned the new find as belonging to the Family incertae sedis (uncertain) origin and linked it to the subfamily Tethysaurinae and was published Wednesday, December 12, 2012.
According to Heti Válasz, almost the entire skeleton of Pannoniasaurus inexpectatus ("Unpredicted or unexpected Pannoniasaur" in Latin) have been coming to light in a bauxite mine at Iharkút, a village north of Veszprém, in north west Hungary. (The article shows an artists' impression of the dinosaur). László Makádi, a paleontologist at the Hungarian Natural History Museum told TG Daily:
"The evidence we provide here makes it clear that similar to some lineages of cetaceans [whales], mosasaurs quickly adapted to a variety of aquatic environments,"
"The size of Pannoniasaurus makes it the largest known predator in the waters of this paleo-environment."
Another rare aspect of the find is that juvenile Pannoniasauri have been found. Usually, paleontologists find the adult members of an extinct animal only.
