Bajadasaurus

O nome significa: “downhill lizard, from the Spanish word bajada (downhill) and the Greek sauros (lizard)”1
Comía: PlantasPescozos longosCretáceo Inferior

Bajadasaurus was a small, long-necked dinosaur that lived in what is now Patagonia, Argentina. It had a row of super long, forward-pointing spines on its neck that probably helped protect it from hungry predators. This plant-eater was about the size of an Asian elephant, small for a sauropod.21

Datos curiosos

1

Bajadasaurus had a pair of extremely long, forward-curving spines on each neck vertebra, forming a kind of spiky fence.1

2

Its skull is one of the most complete ever found for a dicraeosaurid, a group of sauropods with short necks.1

3

The dinosaur had about 48 pencil-shaped teeth, all at the front of its jaws.2

4

Its eye openings were visible from above, which may have helped it look forward while eating low plants.2

5

Bajadasaurus lived around 139 to 133 million years ago, during the Early Cretaceous period.3

6

The only known specimen was found in 2010 by paleontologist Pablo Gallina, preserved as a single block of rock.2

7

It shared its home with other sauropods like Leinkupal and Ninjatitan, as well as meat-eating theropods.2
