The fossil of one of the last living African dinosaurs was discovered in a phosphate mine in northern Morocco. The species, Chenani Saurus barbaricus, is reportedly one of the last ones to have survived on earth before an asteroid strike wiped them out 66 million years ago. Its analysis suggests that a distinct dinosaur fauna evolved in Africa following the breakup of the Gondwana supercontinent in the middle of the cretaceous period. Dinosaurs are known to have lived between 230 and 65 million years ago, a period that is known as the Mesozoic Era.
