The vertebrae were amphicoelous and constricted at the waist, with a length of about three centimetres and somewhat taller than wide in cross-section.

Amphicoelous vertebral centra are a little unusual in a ( relatively ) powerful carnivore, but this was the primitive and usual condition for early synapsids of all types.
These traits include : vestigial tail-wagging muscles, cartilaginous inscriptional ribs, the presence of amphicoelous vertebrae, and nine presachral vertebrae ( most frogs have eight ).

The generic name refers to Rinc�n de los Sauces, where the fossils were discovered, while the specific name, " caudamirus ", means " amazing in the tail " in Latin, in reference to the unusual shape of the tail vertebrae, especially a strange sequence of procoelous, amphicoelous, opisthocoelous, biconvex and ultimately again procoelous vertebrae shown by one individual.
