Piatnitzkysaurus Characteristics

Piatnitzkysaurus measured 14 feet (4.3 metres) in length, 8 feet (2.5 metres) in height and weighed around 275 kilograms. Piatnitzkysaurus was a lightly built medium-sized bipedal dinosaur with short, clawed arms. It had a long stiff tail which it used for counter-balance, ridges on its snout and a distinguished crest on its head. Its body was heavily built and it had a large head on a short neck. Its hind legs were powerful and were equipped with sharp clawed toes on the feet. This dangerous dinosaur had many razor sharp teeth with which it would slice the flesh of its unfortunate prey.


Piatnitzkysaurus was a ferocious carnivore and is thought to have terrorized the plant eaters of that time.


Fossils have been found in Argentina; it is known from 2 fragmentary skeletons, two fractured skulls and parts of the postcranial skeleton


The type specimen, Piatnitzkysaurus floresi, was described by Jose Bonaparte in 1979.
