Thoraciliacus

Thoraciliacus rostriceps is an extinct species of frog from the Cretaceous period and the only species of the genus Thoraciliacus, which is classified in the unranked clade Pipimorpha.[2] Fossils of T. rostriceps were found in Makhtesh Ramon, Negev Desert, Israel and it is believed they lived during the Barremian.[3] Other fossils have been found near Marydale, South Africa in an Upper Cretaceous lake.[3][4]

Description

Thoraciliacus rostriceps was a small frog, 32 millimetres (1.3 in) in length, with a large head. It had short hind limbs but its hands and feet were relatively large.[5] Like its close relative Nevobatrachus gracilis, T. rostriceps was highly aquatic evidenced by its flat skull, short axial column and long metapodials.[6]
