Prettige feite

Osmakasaurus was first thought to be a different dinosaur called Camptosaurus depressus.1

The name Osmakasaurus comes from the Lakota word 'ósmaka' meaning canyon.1

Its fossils were found in the Lakota Formation, which is Early Cretaceous in age, about 137 million years old.1

The only known specimen of Osmakasaurus is a partial skeleton discovered in 1896 by Nelson Horatio Darton.1

Osmakasaurus belongs to a group of plant-eating dinosaurs called iguanodontians, which are relatives of the famous Iguanodon.5 1

Scientists once thought Osmakasaurus belonged to the genus Planicoxa, but later studies gave it its own genus.1 2
