Utuntu dushimishije

1

Achillesaurus is named after the Greek hero Achilles, because its ankle bones were fused together like Achilles' famous tendon.2

2

It lived about 85 to 83 million years ago during the Santonian stage of the Late Cretaceous.1

3

Achillesaurus was a relatively large alvarezsaurid, bigger than its close relative Alvarezsaurus.2

4

Its fossils were found in the Bajo de la Carpa Formation in Argentina, which was a dry, sandy environment.52

5

Unlike some Asian alvarezsaurids, Achillesaurus did not have a highly reduced fibula or a special foot structure called arctometatarsalian.2

6

Scientists are not sure exactly where Achillesaurus fits in the alvarezsaur family tree, because it shares features with both South American and Asian species.2
