Abstract

SOUZA, RAFAEL G. DE  and  CAMPOS, DIOGENES A.. New Crocodyliform specimens from Recôncavo-Tucano Basin (Early Cretaceous) of Bahia, Brazil. An. Acad. Bras. Ciênc. [online]. In press. .  Epub Apr 16, 2018. ISSN 0001-3765.  http://dx.doi.org/10.1590/0001-3765201720170382.

In 1940, L.I. Price and A. Oliveira recovered four crocodyliform specimens from the Early Cretaceous Bahia Supergroup (Recôncavo-Tucano Basin). In the present work, we describe four different fossil specimens: an osteoderm, a fibula, a tibia, and some autopodial bones. No further identification besides Mesoeucrocodylia was made due to their fragmentary nature and the reduced number of recognized synapomorphies for more inclusive clades. With exception of the fibula, all other specimens have at least one particular feature, which with new specimens could represent new species. The new specimens described here increase the known diversity of Early Cretaceous crocodyliforms from Brazil. This work highlights the great fossiliferous potential of Recôncavo-Tucano Basin with regard to crocodyliform remains.

Keywords : Crocodyliforms; Early Cretaceous; Recôncavo Basin; Tucano Basin.
