The Ruehleia is a prosauropod dinosaur that was discovered in a region called Knollenmergel that is roughly thirteen Miles from Schleusingen, southwest of Hildburghausen, Germany. The discovery of this dinosaur was almost complete and consisted of many important fossils of a skeleton such as the cervicals 4-10, dorsals 1-14, partial sacrum, about 20 caudals, right scapula-coracoid, both humeri, right radius and ulna, both manus (incomplete), both pelvic girdles, femora, tibiae and right astragalus.

The Ruehleia was described by Galten in 2001 and named in respect for the famous German paleotologist Hugo Ruehle von Lilienstern.

Ruehleia was a herbivore with three-vertebrae sacrum includes a dorsosacral; ilium with a very large pubic peduncle and an extremely short anterior process, proximal end of the pubis with length of articular surface for ilium much longer than wide with a very short acetabular part (equals half the width of the iliac surface); manus with three large carpals with complicated proximal articular surfaces.
