Comahuesaurus

Comahuesaurus is known from at least three individuals that were buried together in a single bone bed, possibly during a flash flood or landslide.1

Its humerus (upper arm bone) was 67.5 cm (2.21 ft) long and its femur (thigh bone) was 113 cm (3.71 ft) long, showing it was a large sauropod.1

It had a very robust humerus, meaning its front legs were quite sturdy.1

The name Comahuesaurus comes from the Mapuche word Comahue, meaning 'place of abundance' or 'where the water hurt'.3

This dinosaur lived during the Early Cretaceous, about 117 to 100 million years ago.15

At first, scientists thought Comahuesaurus was a species of Limaysaurus, but later they realized it was a new genus because of many unique features in its bones.13
