______________

Eobrontosaurus ("dawn thunder reptile") is the name given to a genus of dinosaur from the Late Jurassic of North America. It was a sauropod probably closely related to Apatosaurus. It is known from a single site from the lower Morrison Formation, dating to about 154 million years ago. It grew up to 21 meters long.

The type species, E. yahnahpin, was described by James Filla and Patrick Redman in 1994 as Apatosaurus yahnahpin. The specific name is derived from Lakota mah-koo yah-nah-pin, "breast necklace", a reference to the pairs of sternal ribs that resemble the hair pipes traditionally worn by the tribe. The holotype is TATE-001, a relatively complete postcranial skeleton found in Wyoming, in the lower Morrison Formation. More fragmentary remains have also been referred to the species.

A re-evaluation by Robert T. Bakker in 1998 found it to be more primitive, and so Bakker coined the new generic name Eobrontosaurus, derived from Greek eos, "dawn", and Brontosaurus, the original generic name of Apatosaurus excelsus. Eobrontosaurus was a member of the Diplodocidae, more specifically the Apatosaurinae.

If not for how the feet turned out, I'd say this looks really nice. I do vaguely recall hearing about Eobrontosaurus too, but this makes for a good reminder.
