Spinosaurus dental remains accounted for 45% of those discovered in a prehistoric river, researchers said
BBC has a story about Spinosaurus. Some researchers believe they have settled the argument around Spinosaurus being an aquatic. This new evidence, which appeared in the journal Cretaceous Research, stems from over 1200 teeth discovered in a prehistoric river deposit. And, it backs up another paper which was published in April. That research looked at the tail of Spinosaurus.
Palaeontologists believe they have settled a debate surrounding the largest ever carnivorous dinosaur.The researchers at the University of Portsmouth say their discovery of 1,200 dinosaur teeth "proves beyond reasonable doubt" that Spinosaurus was an "enormous river-monster".Its dental remains accounted for 45% of those found in a prehistoric river, they said.The findings have been published in the Cretaceous Research journal.Spinosaurus fossils were found in large numbers at the site of an ancient river bed in Morocco, which flowed through the Sahara Desert 100 million years ago.The scientists said their discovery meant the 15-metre (49ft) long, six-tonne dinosaur was not a land-based predator but a largely aquatic one.
