Prettige feite

Leyesaurus had an extremely long neck for its time. Its sixth neck bone was more than five times longer than it was tall, which is unique among early sauropodomorphs.1

This dinosaur is a member of the Massospondylidae family, which were plant-eating dinosaurs that spread across many continents.1

Leyesaurus lived during the Early Jurassic Period, about 201 to 174 million years ago.2

The only known skeleton of Leyesaurus is partially articulated, meaning many bones were still connected when found.1

Leyesaurus had a sharply angled snout, with its upper jaw bone rising at a 50-degree angle.1

KI-prent van Leyesaurus — 'n KI-prent van hoe Leyesaurus 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: Leyesaurus
Benoem deur: Apaldetti et al. 20115
Groep: Langnekke
Familie / klade: Massospondylidae5
Klassifikasie: Sauropodomorpha5
Ouderdom van die rotse: 201 tot 175 miljoen jaar (Hettangian / Toarcian)5
Lande: Argentinië5
Fossielrekords: 1 in The Paleobiology Database5
Ontdekking: Leyesaurus was named in 2011 by Cecilia Apaldetti and colleagues. The fossils were found in the Quebrada del Barro Formation in San Juan Province, Argentina.1
Steeds omstrede: Scientists are not sure exactly how big Leyesaurus grew, because only a partial skeleton has been found.1
