Brasilotitan was a long-necked, plant-eating dinosaur that lived in Brazil during the Late Cretaceous. It was a titanosaur, a group of huge sauropods, but Brasilotitan was smaller than many of its giant cousins.1

酷東西

趣味知識

Brasilotitan had a lower jaw shaped like an 'L', with the front part slightly twisted inward. This feature had never been seen before in any titanosaur.1 2

The name 'nemophagus' means 'pasture eater' or 'wood eater', referring to its plant-based diet.1

Some of the fossil bones show puncture marks, and theropod teeth were found nearby. Scientists think a meat-eating dinosaur may have scavenged the carcass before it was buried.1

Brasilotitan was small for a sauropod, probably less than 12 metres (39 feet) long.1

The fossil includes a right dentary (lower jaw bone), neck vertebrae, part of the sacrum, hip bones, and a toe claw.1 2

Brasilotitan is closely related to another Brazilian titanosaur called Uberabatitan.1
