Description

The Maria Farinha Formation crops out in the Parnaíba Basin in the northeastern state of Pernambuco of Brazil. The formation registers the Cretaceous-Paleogene boundary at the base of the formation, where it overlies the Maastrichtian Gramame Formation. The 14 metres (46 ft) thick formation is overlain by the Eocene Tambaba Formation which is overlain by the Plio-Pleistocene Barreiras Formation.[1]

Fossil content

The following fossils were reported from the formation:[2]

gollark: <@319753218592866315> If you had been paying *any attention*, you could have found other information implying (what I want you to think is) my age VERY EASILY.
gollark: What if RocketRace is part of a Russian disinformation campaign discrediting real disinformation campaigns?
gollark: I am not an idiot. You, however, are an idiot.
gollark: I mean, cars are very scary, several-ton metal boxes hurtling down roads at several tens of metres per second.
gollark: I am still an ageless entity from beyond space and time, Ly¶icly.
