The story in short

The genus Eopinacosaurus dates to 1999, the year P. Godefroit and colleagues described it.

It lived in the Late Cretaceous (Campanian), roughly 83.6 to 72.2 million years ago. Finds come from China, including the Bayan Mandahu Formation. It was a herbivore and walked on four legs.

The fossils of Eopinacosaurus 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 Ankylosaurinae, among the armored dinosaurs.
