The story in short
The genus Achillesaurus dates to 2007, the year A. G. Martinelli and E. I. Vera described it. The name honors a person tied to the fossil or its study.
It lived in the Late Cretaceous (Santonian), roughly 85.7 to 83.6 million years ago. Finds come from Argentina, including the Bajo de la Carpa Formation. It was a carnivore and walked on two legs.
The fossils of Achillesaurus are too incomplete for a responsible length, hip height, or weight, so those fields are left blank on purpose.
On the family tree it sits in Alvarezsauridae, among the theropod dinosaurs.
