This large, sluggish stem reptile lived approximately 250 million years ago. lt grew to about 5 m in length and must have been very clumsy because of its large body and short, thick legs and feet. lts almost hand-shaped teeth had small cusps on the edges and the specimens found are sharp and unworn. It is therefore thought that the animal fed on soft, floating water plants.
Lystrosaurus lived about 220 million years ago in Africa, India, Antarctica, Russia and China, which indicates that the Southern continents were once part of a super continent named Gondwanaland. The animal's eyes, and nostrils were placed high up in the head so that it could protrude only the top of its head above the water like a hippopotamus. lt was probably herbivorous.
This small bipedal reptile was a slender, agile and active animal that was undoubtedly carnivorous. It lived about 200 million years ago. It is generally accepted that Euparkeria was ancestral to the dinosaurs that were to become
the dominant terrestrial animals of later geological periods until this position was taken over by the mammals.
|Commemorative envelope: Emydops
Emydops was a rabbit-sized reptile with a long body and short, stumpy legs. It was herbivorous, with large tusks and small back teeth. The tips of the jaws were covered in horn as is the case in tortoises. It lived about 250 million years ago.
|Commemorative cover with
miniature sheet: Heterodontosaurus
This small, primitive dinosaurus lived about 150 million years ago. It grew to a length of about 1,5 m and was herbivorous. Unlike other dinosaurs it had canine-like teeth near the front of its jaws. The back teeth were adapted to a vegetarian diet.
