The story in short
In 2010, R. D. Juárez Valieri and colleagues published the name Willinakaqe. The name means “southern duck-mimic.”
Fossils referred to Willinakaqe date to the Late Cretaceous (Maastrichtian), roughly 72.2 to 66 million years ago. Finds come from Argentina, including the Allen Formation. It was a herbivore and could move on two or four legs.
The fossils of Willinakaqe 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 Hadrosauridae, among the ornithopod dinosaurs.
