Pachagnathus

Naam beteken: “earth jaw”1

Pachagnathus was a flying reptile that lived in what is now Argentina during the Late Triassic. It is one of the first pterosaurs ever found in the southern half of the world.1 2

Prettige feit: pterosourusse het oor die dinosourusse gevlieg, maar hulle was hul neefs, nie self dinosourusse nie.

Prettige feite

Pachagnathus is known only from a piece of its lower jaw, which is 61.5 mm long and very narrow.1

Its lower jaw has a strange ridge that switches between a single line and a pair of lines between the teeth. No other pterosaur has this.1

Pachagnathus lived far from the coast, in a dry inland area. Most early pterosaurs lived near the sea.1

It was named in 2022, making it a very recently discovered pterosaur.1

Pachagnathus and its relative Yelaphomte are the only definite Triassic pterosaurs from the southern hemisphere.1 2

KI-prent van Pachagnathus — 'n KI-prent van hoe Pachagnathus 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: Pachagnathus
Benoem deur: Martínez et al. 20223
Groep: Vlieënde reptiele
Familie / klade: Raeticodactylidae3
Klassifikasie: Pterosauria3
Ouderdom van die rotse: 227 tot 206 miljoen jaar (Norian)3
Rotsformasies: Quebrada del Barro3
Lande: Argentinië3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Pachagnathus was named in 2022 by Ricardo N. Martínez and colleagues. The only fossil, a piece of lower jaw, was found between 2012 and 2014 in Argentina.1
Steeds omstrede: Scientists are not sure how big Pachagnathus was, because only a small piece of its jaw has been found.1
