Time period: Santonian of the Cretaceous.
Fossil representation: At least two individuals composed of partial skull and post cranial skeletal remains.
easily has one of the hardest genus names to pronounce of any
dinosaur. That aside, Huehuecanauhtlus was a
genus of hadrosauroid
dinosaurs that lived in what is now Mexico during the late Cretaceous.
The region that the Huehuecanauhtlus holotypes are
known from would
have been near the southern tip of the landmass once known as Laramidia
which stretched was made of up the far western portion of North
America, all the way from Mexico to Canada.
As of the late twentieth and early twenty-first centuries, a picture is slowly emerging of Mexico having a very similar collection of dinosaur types as the rest of North America during the Cretacecous, with a diverse range of hadrosaurs, ceratopsians, and probably even tyrannosaurs
