Scientists at the University of Portsmouth in England conducted a study, during which they studied thousands of teeth of the inhabitants of an ancient reservoir. The results indicate that the prehistoric predatory dinosaur Spinosaurus was a waterfowl.

Spinosaurus aegyptiacus is known to viewers from the movie “Jurassic Park III”. Until recently, it was believed that the spinosaurus lived exclusively on land, but the results of a recent study to study the found tail of one of the individuals, proved that the animal was perfectly adapted to life in water. In the new work, scientists have studied the teeth of various creatures living in the river system found in the Kem Kem region and once again confirmed their theory. The fossils were collected from the bed of a prehistoric reservoir. The results showed that it was home to a huge number of spinosaurs.
As experts explained, if an animal spends most of its life in water, then it is natural that it will leave its teeth here. The results obtained fully confirm the theory that the rivers were the habitat of the spinosaurs. In the bed of Kem, many remains of these lizards and other creatures that lived during the Cretaceous period were found. Among other things, the remains of various individuals were found here.
The authors of the scientific work noted that they studied 1200 teeth. The bone formations belonging to the Spinosaurs were easy to identify. They have a distinct surface and a round, smooth cross-section that is visible in the light. As a result, it was possible to determine that 45% of the found number of teeth belonged to Spinosaurs.
