Early Triassic and Anisian marine predators:[1] 7. Aphaneramma

Aphaneramma is an extinct genus of marine temnospondyl amphibian. It lived during the Early Triassic epoch, approximately 252–247 Ma ago, and had a global distribution.

Fossils have been found in the Mianwali Formation of Pakistan,[2] Madagascar,[3] the Zhitkov Formation of Russia,[4] and the Vikinghøgda Formation (Kongressfjellet Formation) of Svalbard (Norway).[5]

Aphaneramma had a skull about 40 centimetres (16 in) in length.[3] Its jaws were very long, similar to the extant gharial's, and lined with small teeth. This adaptation suggests that it may have preyed on fish. A marine lifestyle for this animal was proposed.[1]

Aphaneramma is closely related to Cosgriffius from North America.
