It was about 60 feet long, 12 feet high, and weighed at least seven tons. The Spinosaurus got its name from the massive spikes that ran down its spine.

Are humans prey or predators?

Their new study shows that humans are strange predators. Unlike other animals, we target adult prey in large numbers. That is a practice that can push populations of those prey into decline, the researchers warn. People mainly target — at least among wild mammals and fishes — prey that are old enough to reproduce.

How did early man protect himself from wild animals?
