Dinosaurs and Other Monsters

FLASHING A MOUTHFUL of 15-centimeter-long teeth like serrated knives, Tyrannosaurus rex ripped flesh from bone—and not just at mealtimes.

Ichthyosaurs, those fish-shaped lizards with sinuous bodies that measured twice the height of a human, chased lesser monsters through the open oceans. Some of the birds could have given Alfred Hitchcock fresh nightmares: two-meter-tall phorusrhacoids sprinted at 70 kilometers an hour and snapped their massive beaks on victims, beat them senseless against the ground and then swallowed them whole.
