Aucasaurus was a carnivore (meat-eater) that lived in South America
(its fossils have
been found in the Auca Manhuevo region of Argentina).
It lived during
the late Cretaceous period,
between about 84 and 71 million years ago.
Aucasaurus was closely related to Carnotaurus,
but considerably smaller in size.
Aucasaurus was about 13 feet (4 meters) long, and stood about 3½ feet (1 meter) tall at
its hips. It probably weighed around 1,500 pounds (700 kilograms).
"Aucasaurus" means "Auca lizard". It is named after Auca Manhuevo, the region of Argentina where its fossils were discovered.
Aucasaurus was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Aucasaurus was not closely related to lizards, it did have similarly shaped pelvic bones.
Aucasaurus was a Theropod - a member of a group of related bipedal dinosaurs that included the ancestors of birds (although Aucasaurus was not itself an ancestor of birds).
Aucasaurus lived between about 81 million years ago and 74 million years ago, during the late Cretaceous period.
