Author: Janensch
Year: 1929

Definition

About
Four-legged, flagellicaudatan diplodocoid sauropods—the "whip-tailed" relatives of Diplodocus. Relatively small compared to other sauropods, dicraeosaurids (members of Dicraeosauridae) have extremely short necks with long "forked" spines on the vertebrae of their necks and backs.

Etymology
Dicraeosauridae is derived from the Greek "dikraios" (bifurcated, double-headed) and "sauros" (lizard), named for the long "forked" neural spines on the vertebrae of the neck and back, and their relationship to Dicraeosaurus.
