The story in short
In 2021, F. L. Agnolín and colleagues published the name Guemesia. The name honors a person tied to the fossil or its study.
Fossils referred to Guemesia date to the Late Cretaceous (Campanian · Maastrichtian), roughly 83.6 to 66 million years ago. Finds come from Argentina, including the Los Blanquitos Formation. It was a carnivore and walked on two legs.
The fossils of Guemesia are too incomplete for a responsible length, hip height, or weight, so those fields are left blank on purpose.
On the family tree it sits in Brachyrostra, among the theropod dinosaurs.
