| Popis: | The holotype of the titanosaur sauropod Rinconsaurus caudamirus, from the Bajo de la Carpa Formation (Santonian, Upper Cretaceous, Neuquen Group), is based on an articulated series of 13 anterior-middle to middle posterior caudal vertebrae and two illia, in addition to cranial, axial and appendicular elements corresponding to several individuals. One of the skull elements originally identified as a prefrontal (MAU-Pv-CRS-102), is reinterpreted here as a mesoeucrocodylian right ilium, likely belonging to Pehuenchesuchus enderi, a crocodyliform found in the same quarry. Therefore, this element is excluded from the Rinconsaurus type materials, adding a new element to Pehuenchesuchus and increasing the knowledge of its anatomy. |
