Dicraeosaurinae

(Janensch 1929)

Dicraeosauridae is a family of diplodocoid sauropods who are the sister group to Diplodocidae. Dicraeosaurids are a part of the Flagellicaudata, along with Diplodocidae. Dicraeosauridae includes genera such as Amargasaurus, Suuwassea, Dicraeosaurus, and Brachytrachelopan. Definitive genera of this family have been found in North America, Africa, and South America. The Asian taxa Lingwulong and Tharosaurus have been suggested to be dicraeosaurids, but some authors disagree with this classification. Their temporal range is from the Early or Middle Jurassic to the Early Cretaceous. Few dicraeosaurids survived into the Cretaceous, the youngest of which was Amargasaurus.
