Fun facts

1

Baurutitan was one of the first four sauropod dinosaurs ever described from Brazil.1

2

Its fossils were discovered in 1957 by paleontologist Llewellyn Ivor Price, but the dinosaur was not named until 2005.1

3

The name Baurutitan comes from the Bauru Group of rocks where it was found, plus 'titan' from Greek mythology.1

4

Scientists think Baurutitan might be the same animal as another dinosaur called Trigonosaurus.2

5

Baurutitan lived during the Maastrichtian age, about 72 to 66 million years ago.4

6

The only known fossils of Baurutitan are a series of tail bones and a hip bone.1
