Yelaphomte

Yelaphomte (Allentiac, "beast of the air") is an extinct genus of non-pterodactyloid pterosaur from the late Norian–early Rhaetian-aged Quebrada del Barro Formation of Argentina. It lived in the Late Triassic period (somewhere between 217-201 million years ago), and is one of the only known definitive Triassic pterosaurs from the southern hemisphere (along with the contemporaneous and related Pachagnathus). It was a small and crested pterosaur, although its small size may be due to immaturity. It is also one of the few known continental Triassic pterosaurs, indicating that the absence of early pterosaurs in both the southern hemisphere and terrestrial environments is likely a sampling bias, and not a true absence.

== Discovery and naming == The type and only known specimen of Yelaphomte, PVSJ 914, was collected during fieldwork by the Museo de Ciencias Naturales of the Universidad Nacional de San Juan from 2012 to 2014. It consists of only a fragment of the rostrum preserving the anterior part of both maxillae and palatines from the anterior border of the naris, as well as a posterior portion of both premaxillae, all preserved in three dimensions and undistorted. It was first reported on in 2015 by Martínez et al., although at the time the specimen was not fully prepared and could not be identified as anything more diagnostic than an indeterminate pterosaur. PVSJ 914 was later fully described and named by Martínez et al. (2022) as a new genus and species, Yelaphomte praderioi, along with other pterosaur remains from the Quebrada del Barro Formation (including the related Pachagnathus).
