3. An odd, fresh-water dwelling reptile (not a dinosaur. It was a lightly-built, four-legged animal with an elongated head and snout with nostrils near its eyes. It had a flattened tail that was probably used for swimming. It was about 1.5 feet (45 cm) long. This carnivore probably ate fish and shrimp, catching them with its mouth.
6. This historic animal was about the size and weight of a modern pig. The structure of the skull, with the nostrils and eye sockets placed near the top of the head, the snout turned down at the tip and the teeth and jaws placed low, all suggest that Lystrosaurus found food in the water, in much the same fashion as the living hippopotamus.
