酷東西

趣味知識

Jiangxititan is known from only seven back bones (three neck and four chest vertebrae) with ribs attached.1

Its neck and front chest bones were very flat from top to bottom, which is unusual for sauropods.2

The neural spines on its neck and front back bones were deeply split into two branches, making a V shape.2

Jiangxititan lived alongside another sauropod called Gannansaurus, but Gannansaurus was from a much older lineage.2

Scientists disagree about Jiangxititan's family tree: some say it was a true titanosaur, others think it was a more primitive somphospondylan.1
