Altanulia is an extinct genus of prehistoric amphibian.[1]

Description

[edit]

The holotype of Altanulia - PIN 553/300 -, consisting of an isolated 20 mm long maxilla bearing 45-47 teeth, was found by the Soviet-Mongolian Paleontological Expedition in the southern Gobi Desert, Nemegt Formation, and dates from the Upper Cretaceous (Upper Campanian-Lower Maastrichtian). Altanulia was diagnosed on the basis in the "Posterior part of maxilla deep, with longitudinal wedge-shaped labial depression; pterygoid tubercle of maxilla well expressed; frontal process in anterior part of bone."[2]

Classification

[edit]

Altanulia belongs to the Discoglossidae, due to the shape and structure of the lingual surface of its maxilla.[2]
