Encyclopedia
Unwindia is a genus
of basal
ctenochasmatoid
pterosaur
from the Late Cretaceous
of northeastern Brazil
. It is known from a partial skull
recovered from rocks of the Santana Formation
of the Araripe Basin, dating to Cenomanian
stage. It was named by David M. Martill in 2011
and the type species is Unwindia trigonus.

Cenomanian
The Cenomanian is, in the ICS' geological timescale the oldest or earliest age of the Late Cretaceous epoch or the lowest stage of the Upper Cretaceous series. An age is a unit of geochronology: it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding...
