I guess this one slipped by without getting proper attention. In October of 2007 research described a new genus of species of crocodylian, Montealtosuchus arrudacamposi (pictured above) in the journal Zootaxa. It was a late Cretaceous member of the Peirosauridae found in Bauru Basin, Brazil, although it was only one representative of a larger diversity of crocodylians from the location that also included notosuchids, sphagesaurids, baurusuchids, and trematochampsids. Unfortunately the paper is behind a subscription wall (the issue in which it can be found is located here, a pdf of the abstract and excerpt being located here).
Update: A kind reader has sent the paper along (thank you!), so I’ll have something more substantial about this creature sometime soon.
