Proa

Igama lithetha: “prow, because its beak bone looked like a ship's prow”1

Yayitya: IzityaloIzitya-zityalo ezinemilomoiCretaceous yokuqala

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.1 2

izinto ezimnandi

Iinyani ezimnandi

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

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

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

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

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

Umfanekiso owenziwe yi-AI: Proa — Umfanekiso owenziwe yi-AI obonisa indlela Proa esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

Ukufunyanwa: Proa was named by Andrew T. McDonald and colleagues in 2012, based on fossils from coal mines near Val de Ariño in Spain.1
Kusaxoxwa ngayo: 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
