An article published in the journal “Cretaceous Research” reports the discovery of hundreds of teeth of Spinosaurus aegyptiacus in the ancient Kem Kem river system, along the border between today’s Morocco and Algeria. A team of researchers collected about 1,200 fossil teeth in an ancient river bed in today’s Morocco, and analysis revealed that nearly half of them were of Spinosaurus aegyptiacus. Their conclusion is that it’s evidence that about 100 million years ago, in the Cretaceous period, this dinosaur was well adapted to aquatic life, a confirmation of the thesis supported by a growing number of paleontologists.
