Did carcharodontosaurs make it to the very end?

10-10-2019 8:15pm#1New theropod teeth from the latest Cretaceous (Maastritchian) of Brazil have been found and analyzed. Some of them seem to belong to abelisaurs, but the most interesting ones seem to be from carcharodontosaurs, which were supossed to have went extinct long before the late Cretaceous.
Of course, being just teeth, we can´t be sure- they may belong to some other kind of theropod that developed similar diet habits/teeth, or even to crocodilians. When the blade-like, serrated teeth sebecids were found for the first time, scientists believed non-avian theropods had made it to the Eocene in South America, because the teeth were so similar.
EDIT: A later study found that these teeth may belong to abelisaurids after all.
I have to admit it's an exciting idea, tho- to have T. rex and carcharodontosaurs walking the Earth at the same time, albeit in different places.
