Tralkasaurus was a medium-sized meat-eating dinosaur that lived in what is now Argentina. It was a type of abelisaurid, a group of predators known for their short snouts and strong legs. Tralkasaurus was smaller than many of its relatives, so it probably hunted different prey.2 1

Tralkasaurus was named in 2020, making it a relatively new dinosaur discovery.4

Its name comes from the Mapudungun word 'tralka' meaning thunder, and the Greek word 'sauros' meaning lizard.1

Tralkasaurus lived during the Early Cretaceous period, about 106 million years ago.1

Only one incomplete skeleton of Tralkasaurus has been found, including parts of the skull, backbone, and hip.1

Tralkasaurus was smaller than other abelisaurids like Abelisaurus and Carnotaurus, so it probably filled a different role in its ecosystem.2

The maxilla (upper jaw bone) of Tralkasaurus is 22 centimeters (8.7 inches) long, which is smaller than that of the related Skorpiovenator.1
