Bayannurosaurus was named in 2018, making it a recently discovered dinosaur.1

Its species name 'perfectus' means 'perfect' because the fossil was so well preserved.1

This dinosaur lived about 124 million years ago during the Early Cretaceous period.1

Bayannurosaurus was an iguanodontian, a group of plant-eating dinosaurs that often walked on two or four legs.1

The nearly complete skeleton included the entire tail, which helps scientists understand how it moved.1

Scientists think Bayannurosaurus was more advanced than Hypselospinus but less advanced than Ouranosaurus.1
