Chenanisaurus barbaricus

The phosphate mines of Morocco are one of the richest fossil sites in the world. Producing vast numbers of shark and mosasaur teeth, they may be the largest fossil dig in the world. They represent the remains of an incredibly productive ancient sea. At the time, sea levels were high, flooding North Africa, and the plains south of the Atlas Mountains were a shallow sea, full of mosasaurs, elasmosaurs, marine turtles, and sharks. Giant marine pterosaurs wheeled overhead. Oceans aren’t the first place you’d search for a dinosaur, however.
