They lived on the continent from at least 24 million years ago until 50 000 years ago and perhaps more recently still. Brougham put the nostrils on his protoceratops far forward, near its beak, following the example of most living creatures. If an 80-foot dinosaur such as Apatosaurus took decades to grow to sexual maturity, there would be very few of them left to mate by the time they matured.
