Udelartitan was a long-necked plant-eating dinosaur that lived in what is now Uruguay. It was about as long as a school bus and walked on four sturdy legs. This titanosaur is one of the most complete sauropods ever found in Uruguay.3 1

酷東西

趣味知識

Udelartitan had a special first tail vertebra that was biconvex, meaning it was rounded on both ends like a ball. This is rare among sauropods.1

Scientists found 60 tail vertebrae from one Udelartitan, which is a lot for a sauropod.1

Udelartitan lived during the Late Cretaceous period, about 100 to 84 million years ago.3

The fossils of Udelartitan were discovered in 2006 in a gully in Uruguay.2

Udelartitan is a saltasauroid, which is a group of titanosaurs that includes some of the smallest sauropods.1

發現: Udelartitan was named in 2024 by Matías Soto and colleagues. The fossils were found in 2006 near Quebracho, Uruguay, and include bones from at least two individuals.3 2
仍有爭議: Scientists are not sure whether Udelartitan was a saltasaurine saltasaurid or a non-saltasaurid saltasauroid. They also debate the exact age of the rocks where it was found.1
