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

Het geëet: PlantePlantvreters met snawelsVroeë Kryt

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

Prettige feite

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

KI-prent van Proa — 'n KI-prent van hoe Proa dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.

Vir dino-kenners

Wetenskaplike naam: Proa
Benoem deur: McDonald et al. 20124
Groep: Plantvreters met snawels
Familie / klade: Hadrosauriformes4
Klassifikasie: Ornithischia > Ornithopoda > Iguanodontia4
Ouderdom van die rotse: 113 tot 110 miljoen jaar (Albian)4
Rotsformasies: Escucha4
Lande: Spanje4
Fossielrekords: 1 in The Paleobiology Database4
Ontdekking: Proa was named by Andrew T. McDonald and colleagues in 2012, based on fossils from coal mines near Val de Ariño in Spain.1
Steeds omstrede: 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
