Euhelopodidae

Euhelopodidae is a family of sauropod dinosaurs of disputed membership and affinities, which contains Euhelopus and its close relatives. Most proposed euhelopodids are from East Asia.

Euhelopodidae was first recognized by Carl Wiman in 1929, under the name Helopodidae, as Euhelopus was originally named Helopus. However, the name had already been proposed for a bird, so in 1956 Alfred Sherwood Romer proposed the name Euhelopus and Euhelopodinae as replacements; Romer classified Euhelopodinae as a subfamily of Brachiosauridae, in which he also included Camarasaurinae and Cetiosaurinae, rather than as a family of its own. In addition to Euhelopus itself, Romer included Chiayusaurus, Omeisaurus, and Tienshanosaurus in Euhelopodinae.
