  The same split-carinate tooth? Or additional teeth in the same Group, but not 
Formation, or the same Formation? 'Cause this would be interesting. The 
abstracts seems to purport this is the first such tooth of a taxonomic nature, 
rather than just the carinate variation.

The full ref is at:


Improbably long ScienceDirect link....

"An updated, annotated list of all tetrapods from the Adamantina, Uberaba and 
Marília formations (Bauru Group), which constitute some of the best studied 
Upper Cretaceous units in Brazil, is presented. Tetrapod diversity in the Bauru 
Group is remarkable, including an admixture of typically austral Gondwanan taxa 
(e.g., abelisaurids, notosuchians) and boreal Gondwanan forms (e.g., 
carcharodontosaurids). Of note is the absence of Laurasian taxa in the upper 
portion of the Bauru Group. With the exception of some turtles, an anuran, 
mesoeucrocodylians and one titanosaur, most taxa from the Bauru Group are based 
on fragmentary and isolated bones, and as such many specimens can be identified 
only to a higher taxonomic level. Fishes, turtles, anurans, mesoeucrocodylians, 
dinosaurs, birds and mammals from the Adamantina and Marília formations 
resemble the latest Late Cretaceous vertebrate faunas from southern South 
America, except for the absence of
 ornithischian dinosaurs."
