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

Utuntu dushimishije

1

Astigmasaura is one of the youngest rebbachisaurid dinosaurs ever found, living near the end of the group's existence.1

2

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

3

The fossil includes an almost complete pelvis and a series of tail vertebrae, which is rare for rebbachisaurids.1

4

Astigmasaura had tall neural spines on its front tail vertebrae, which helped attach strong muscles.1

5

It lived in the same time and place as giant titanosaurs, but was a smaller, more lightly built sauropod.1

Ishusho yakozwe na AI yerekana uko Astigmasaura ishobora kuba yari isa, yakozwe na mudasobwa hashingiwe ku byo abahanga bazi. Ni ugukeka gusa: inyamaswa nyayo ishobora kuba yari isa ukundi, kandi nta muntu uzi amabara yayo nyayo.

Scientists are still debating exactly how Astigmasaura is related to other rebbachisaurids, and whether it was a more basal or more advanced member of the group.1
