Astigmasaura
Astigmasaura was a long-necked plant-eater that lived in what is now Patagonia, Argentina. It was a rebbachisaurid sauropod, a group of dinosaurs that were medium to large in size and walked on four legs. Astigmasaura lived alongside giant titanosaurs during the Late Cretaceous.51

Datos curiosos
Astigmasaura is one of the youngest rebbachisaurid dinosaurs ever found, living near the end of the group's existence.1
Its name comes from the Spanish word 'orejano', which means a stray animal without an owner, because it was found in the El Orejano locality.1
The fossil includes an almost complete pelvis and a series of tail vertebrae, which is rare for rebbachisaurids.1
Astigmasaura had tall neural spines on its front tail vertebrae, which helped attach strong muscles.1
It lived in the same time and place as giant titanosaurs, but was a smaller, more lightly built sauropod.1
