He discovery of more than a thousand fossil teeth of Spinosaurus, the giant predator made famous by the movie Jurassic park iii, shows that it was a huge river monster.
The study, published by researchers at the University of Portsmouth in the journal Cretaceous Research, shows that Spinosaurus aegyptiacus, a 15 meter long and six ton beast, it was in fact the most commonly found creature in the Kem Kem river system, which crossed the Sahara desert 100 million years ago.
Until very recently dinosaurs were believed to live exclusively on land. However, research published earlier this year showed that Spinosaurus was well adapted to an aquatic lifestyle, due to its newly discovered tail. This latest investigation of 1,200 teeth found in the same region further supports this theory.
Scientists from the University of Portsmouth collected the fossilized remains from an ancient riverbed site in Morocco. After analyzing all of them, it was discovered that there were a large number of Spinosaurus teeth, which are distinct and easily identifiable.
David Martill, a professor of paleobiology at the University of Portsmouth, said: “The huge number of teeth we collected from the prehistoric river bed reveals that Spinosaurus was there in large numbers, accounting for 45 percent of the total dental remains. We do not know of any other place where such a mass of dinosaur teeth has been found.
“The increased abundance of Spinosaurus teeth, relative to other dinosaurs, is a reflection of its aquatic lifestyle. An animal that lives much of its life in water is far more likely to contribute teeth to the river reservoir than dinosaurs that perhaps only visited the river to drink and feed along its banks. From this research, we can confirm this place as the place where this gigantic dinosaur not only lived but also died. The results are fully consistent with the idea of a true ‘river monster’ aquatic dwelling. ”
