Known as one of the oldest kinds of dinosaurs, Herrerasaurus
had carnivorous features: a big jaw, sharp teeth, and features favorable
for hunting such as long claws and quick and nimble legs.
Being about 3~4m long and weighing 250~300 kg, it was a biped ambulatory animal.
It inhabited the northwestern areas of Argentina during the latter part of
the Triassic period.

As a quick and agile dinosaur, its front legs were very short and
its body except for the tail was a little bigger than a turkey.
In 1947, hundreds of Coelophysis fossils were found in Ghost Ranch, New Mexico.
Unlike other large, carnivorous dinosaurs, Coelophysis seemed to have
lived in groups, moving in herds.
Its body was 3 m at longest and weighed 15-30 kg.
|
As the largest among Triassic-age dinosaurs, it had a small
head, long neck, shorter front legs as compared to its well-developed hind legs.
It walked on four legs.
The big toe had a big claw, which seemed to have been used either for hunting or as a weapon.
Its fossils have been found in more than 50 areas in Europe.
This herbivorous dinosaur stood 9 m long and weighed 4 tons.

Riojasaurus, with legs as thick and robust as an elephant
and a long neck, had a non-proportionally longer tail, which seemed to
have been used either for balance or as a weapon.
It grabbed its food using five, long, front toes.
Like other herbivorous dinosaurs, it had spoon-shaped teeth.
It stood 11 m long and weighed 4.5 tons.
