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

Inyani emnandi: iipterosauri zazibhabha phezu kweedayinaso, kodwa zazingabazala bazo, hayi iidayinaso ngokwazo.

izinto ezimnandi

Iinyani ezimnandi

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

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

Igama lenzululwazi: Pachagnathus
Inikwe igama ngu:: Martínez et al. 20223
Iqela: Izirhubuluzi ezibhabhayo
Usapho / iclade: Raeticodactylidae3
Ukuhlelwa: Pterosauria3
Ubudala bamatye: 227 ukuya ku-206 izigidi zeminyaka (Norian)3
Izakhiwo zamatye: Quebrada del Barro3
Amazwe: i-Argentina3
Iirekhodi zeefosili: 1 kwi-Paleobiology Database3
Ukufunyanwa: 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
Kusaxoxwa ngayo: Scientists are not sure how big Pachagnathus was, because only a small piece of its jaw has been found.1
