吃：植物長脖子恐龍白堊紀早期

Choconsaurus was a long-necked plant-eater that lived in what is now Argentina. It is one of the most complete titanosaur skeletons ever found from its time. This dinosaur helps scientists understand how titanosaurs evolved.1

趣味知識

Choconsaurus is known from a nearly complete series of back bones (dorsal vertebrae) and other parts of the skeleton.1

It lived during the Late Cretaceous, about 100 million years ago, in the Huincul Formation.1

Choconsaurus is a non-eutitanosaur titanosaur, meaning it was an early relative of the giant titanosaurs like Argentinosaurus.1

It had a small notch on the top of the back part of its neck bones, which is a unique feature not seen in other sauropods.1

Its tail bones had a special ridge called a hyposphene, which helped lock the vertebrae together for extra strength.1
