Proa was a plant-eating dinosaur that lived about 112 million years ago in what is now Spain. It had a pointed beak and walked on two legs, but could probably also drop to all fours. It was a relative of the bigger duck-billed dinosaurs.12

Dintlha tse monate

1

Proa's beak bone had a pointed tip with side prongs that stuck out, which is unique among its relatives.1

2

It lived during the Early Cretaceous, about 112 million years ago, which was a time when many new dinosaur groups were appearing.1

3

Proa is known from at least three partial skeletons and several skull pieces, so scientists have a good idea of what it looked like.1

4

It was a basal iguanodont, meaning it was an early relative of the bigger iguanodons and duck-billed dinosaurs.3

5

Proa helps fill a gap in the fossil record of European iguanodonts, which was missing for millions of years.3

Proa was named by Andrew T. McDonald and colleagues in 2012, based on fossils from coal mines near Val de Ariño in Spain.1
E sa ntse e phehwa kgang
Scientists are still debating exactly where Proa sits on the dinosaur family tree, with some placing it close to Iguanodon and others with Asian relatives.1
