The Spondylosoma is not confirmed and much remains unknown about it. Some paleotologists say that it really is only a saurischian dinosaur, but it has been re-classified as a Rauisuchian by Huene in 1942 making it officially not a dinosaur. The fossils were found in Lower Santa Maria Formation of Rio Grande do Sul, Brazil. The fossils found were skeleton includes two teeth, two cervical vertebrae, four dorsal vertebrae, three sacral vertebrae, scapulae, part of a humerus, part of a femur, and part of a pubis whcih was held at the University of Tübingen.

Although not a dinosaur it did atribute many common body features such as elongate pubis, at least three sacral vertebrae, dorsal vertebrae having accessory hyposphene-hypantrua articulations which were like dinosaurs, however the Rauisuchian Reptile also shared this in common with dinosaurs. Another important factor is that according to Galton(a dinosaur describer), he claimed that the sacrum of S. indicate that this creature did belong to the reptile family as opposed to the dinosaur family.
