Ostafrikasaurus was a carnivorous theropod dinosaur from the Late Jurassic of southeastern Tanzania.[1] It is known only from a fossil tooth that is 49 mm (1.9 in) long. Paleontologist Eric Buffetaut claims it is the oldest evidence of a Spinosaurid dinosaur (a type of crocodile-like dinosaur that ate fish); It appeared 148 million years ago.[2]
