Mesophryne
Extinct genus of amphibians / From Wikipedia, the free encyclopedia
Mesophryne beipiaoensis is an extinct species of frog, from the Cretaceous Yixian Formation of Liaoning (China), and the only species in the genus Mesophryne. It is known from a single specimen collected near Heitizigou, 25 kilometres (16 mi) south of Beipiao, from which the specific epithet derives. The specimen has a snout–vent length of 69 millimetres (2.7 in).[1] While some authors have suggested Mesophryne is a synonym of Liaobatrachus, this has been rejected by other authors. In a phylogenetic analysis it was found to be a crown group frog, which was more derived than Ascaphus and Leiopelma, but less so than alytids and other more advanced frogs.[2]
