Postcranial Skeleton of the Upper Paleocene (Itaboraian) “Condylarthra” (Mammalia) of Itaboraí Basin, Brazil

The Itaborai Basin, in the state of Rio de Janeiro, is one of the smallest depositional basins in Brazil and is the only one to have yielded a terrestrial fauna of late Paleocene age. For 50 years its limestone was commercially exploited, allowing the recovery of a great amount of fossil vertebrates, predominantly from fissure fill deposits (Sequence S2 sensu Medeiros and Bergqvist, 1999), of Itaboraian age. Among the vertebrates, the fossil mammals are the most abundant, with marsupials being the most diverse but ungulates the most abundant. Fossil edentates are very rare. Since the end of the 1980s, the Itaborai basin has been completely flooded and no further fossil collecting has been possible (Figure 6.1).

Among the ungulates, the “condylarths” comprise the second least abundant group next to the Xenungulata. The relationships of most “condylarths” are very uncertain and they probably represent a paraphyletic assemblage. Some authors have advocated abandonment of the concept of Condylarthra altogether. Herein I follow the concept of “Condylarthra” as advocated by Archibald (2005), and the recommendation of Prothero et al. (1988) to add quotation marks to the term “condylarth” in order to emphasize its paraphyly, as already done by Muizon and Cifelli (2000).
