A new species of a bizarre notosuchian mesoeucrocodylian is reported here. Caryonosuchus pricei gen. et sp. nov. was found in the outcrops of the Adamantina Formation (Campanian–Masstrichtian) in São Paulo State, Brazil, and shows a typical sphagesaurid dentition: strong and short teeth, obliquely implanted with the crown of the upper teeth showing a rounded anteriolabial margin and a strong compressed posteriolingual edge developed into a carina, ornamented by developed ridges and denticles. Amongst the diagnostic features of the new taxon are the presence of horn‐like tubercles on the premaxilla and maxilla, never reported in this group before. The occurrence of C. pricei increases the diversity of sphagesaurids and confirms that all members of this clade, only recorded in Late Cretaceous deposits from Brazil so far, share the same dentition. © 2011 The Linnean Society of London, Zoological Journal of the Linnean Society , 2011, 163 , S57–S65.
