Spinosaurus teeth found in ancient Kem-Kem river system


Paleontologists found 1200 Spinosaurus teeth in the ancient Kem-Kem river system. The findings reflected the aquatic lifestyle of the dinosaur.

Paleontologists from the University of Portsmouth discovered 1200 teeth of the Spinosaurus from the ancient Kem-Kem riverbed, situated in the middle of Morocco and Algeria. The researchers have found out that the Teeth belonged to the Spinosaurus.

Spinosaurus was an aquatic animal, and this discovery proved that S. aegyptiacus lived under the water. This discovery confirmed the old theories, which showed the species of dinosaurs who lived under the water.


Spinosaurus was a specie of dinosaur, and in simple words, it was a reptile. They roamed around the Earth 3.23 million years ago in the Triassic period. Experts say that the exact time of the evolution among the Spinosaurus is still a subject of research.

The meaning of a Spinosaurus is spine lizard. A German paleontologist Ernst Stromer discovered the specie named S. aegyptiacus in 1915. During World War two, the remains of the Spinosaur were demolished. But the additional fossils came forward in the early 21st century.

It was the largest dinosaur among all carnivorous dinosaurs. The length of Spinosaurus was 41 to 59 feet, and the weight was 7 to 20.9 metric tons. The research shows that this dinosaur survived in both water and land, just like the crocodiles.

Information given by Paleontologist

While digging ancient river, the team of Paleontologists found 1200 teeth of Spinosaurus. Those Paleontologists belonged to the University of Portsmouth. The scientists discovered most of the teeth of the dinosaur in the Ancient Kem-Kem Riverbed. The river beds are situated between Morocco and Algeria and are a hub of geological formations.

This discovery gives a strong report on the habitat of Spinosaurus. The teeth were not discovered on the banks of the river, but they were found under the water. The researches also confirmed that it spent most of its time under the water.

Thus, the Paleontologists speculated that the daily activity of Spinosaurus was similar to that of a crocodile or Hippo. David Martill, a professor of Paleontology at the University of Portsmouth, said that “As compared to other dinosaurs, the Spinosaurus’s teeth are more abundant.”

David Martill also said that when we compare the two types of animals, those who roamed above the land and those who spent most of their lives in water.

The researchers admitted that aquatic animals are more likely to shed their teeth underwater than land animals. This theory proved that the Spinosauruses were more of a marine animal than that of a land animal.
