“A giant fossil, unearthed in the Sahara desert, has given scientists an unprecedented look at the largest-known carnivorous dinosaur: Spinosaurus. The 95-million-year-old remains confirm a long-held theory: that this is the first-known swimming dinosaur.
The researchers say that Spinosaurus lived in a place they describe as “the river of giants”, a waterway that stretched from Morocco to Egypt. They believe it would have feasted on giant sharks and other car-sized fish called coelacanths and lungfish, competing with enormous crocodile-like creatures for its prey.”
