is a genus of abelisaurid
dinosaur that lived in South America during
the late Cretaceous. At the time of writing Guemesia
is known only
from a braincase, which makes physical details beyond generic
abelisaurid traits hard to determine. The size of the braincase
however suggests that Guemesia may have actually
been quite small, at
least compared to other abelisaurid dinosaurs.
