A new sauropod Titanosauridae, Panamericansaurus schroederi from the Allen Formation (Campanian), Neuquén province is reported here. The holotype was found in Late Campanian outcrops of NW Patagonia, Argentina. This new taxon is deeply nested within a South American Titanosaurid, named Aeolosaurini. Within Aeolosaurins, it shares all synapomorphic characters except that the anterior margin in anterior and middle caudals is not directed anterodorsally; this morphology is also present in A. colhuehuapensis. P. schroederi is unique in presenting on mid-posterior caudal vertebrae, prezigapophysis directed anterodorsaly with the length equal to or shortended than the length of ventral centrum, postzigapophysis are placed in the middle of the ventral centrum; the spinoprezigapophyseal lamina expanded dorsoventrally in middle caudals and the robust index of humerus is less than 0,40 different to other Aeolosaurins. It is the first record of a dinosaur at Allen Formation in Neuquén province. |
