Caudal vertebrae "Aeolus's lizard"  (Lat. Aeolus, god of the winds in Greek and Roman mythology + Gr. sauros "lizard") (m) regarding  the windy Patagonian region of southern Argentina where the fossil was found.

Remains: 5 tail vertebrae, ulna, radius, metacarpal, pubis, ischium, dermal plates MPCA 27174: 5 caudal vertebrae, right ulna, metacarpal, left pubis, right ischium MPCA 27175: right ulna & radius MPCA 27176: osteoderm MPCA 27177: osteoderm A. rionegrinus: MJG-R 1 [holotype]: 7 anterior caudal vertebrae; partial forelimbs; right tibia, fibula, & astragalus; fragments ?MACN-RN 147: 15 articulated caudal vertebrae

Remains assigned to Aeolosaurus Powell, 1986 from the Rio Colorado Fm (or Allen Fm) are described. The specimen differs from the holotype of Aeolosaurus rionegrinus Powell, 1986 in the lenght of the prezigapophyses, relative possition of the postsigapophyses, and radius and ischium morphology. Considerations on a specimen tentatively assigned to the type species, and modified diagnosis of genous are included. Association of dermal plates to the specimen is commented in Salgado & Coria Ameghiniana, 1993. 30 (2):1-19

The obtained fossils contributes additional information on the anatomy of this sort. Different characters are considered probable apomorphic of Aeolosaurus . The subfamily Titanosauridae can represent a paraphyletic group since they  do not recognize a synapomorphic of Titanosaurus + Aeolosaurus (Coria & Calvo Geociencias.1997. II(6):44-49)
