Baurubatrachus

Baurubatrachus is an extinct genus of prehistoric frogs found in the Maastrichtian Marília Formation of Brazil, formerly considered to be related to the extant family Ceratophryidae. However, a detailed assessment of the anatomy and relationships of the single known fossil of "Baurubatrachus" demonstrated that it is not part of Ceratophryidae and might be part of a much ancient group of Neobatrachia.
