The story in short
In 2011, A. T. McDonald published the name Osmakasaurus. The name means “canyon lizard.”
It lived in the Early Cretaceous (Berriasian · Valanginian), roughly 143.1 to 132.6 million years ago. Finds come from the United States, including the Lakota Formation. It was a herbivore and walked on two legs.
The fossils of Osmakasaurus 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 Ankylopollexia, among the ornithopod dinosaurs.
