<p>Lissamphibian assemblages of Early Cretaceous age are rare in Europe. Here, we comprehensively describe the most informative lissamphibian remains from the Lower Cretaceous (Barremian–Aptian) Balve locality in Germany. The assemblage from Balve includes the salamandroid salamanders <i>Balveherpeton hoennetalensis</i> and <i>Martintriton septatus</i> gen. et sp. nov., as well as the albanerpetontid <i>Wesserpeton</i> sp. and an indeterminate frog (Anura indet.). <i>Martintriton septatus</i> gen. et sp. nov. is characterised by the following combination of atlantal characters: anterior cotyles large and rounded with almost flat articular surfaces continuous across lateral and ventral surfaces of broad intercotylar tubercle; posterior cotyle oval and laterally compressed; prominent ventrolateral ridges; irregularly located depressions separated by bony septa and several foramina of different sizes on ventral surface of centrum; short lateral ridge on lateral surface of centrum; and large foramina between the lateral and ventrolateral ridges. <i>Martintriton septatus</i> gen. et sp. nov. shares similarities in atlas morphology with the Paleogene batrachosauroidid <i>Palaeoproteus miocenicus</i> and the Late Cretaceous scapherpetids likely indicating a close relationship. The composition of the lissamphibian assemblage from Balve (= faunal association “frogs-crown salamanders-albanerpetontids”) resembles other most diverse Early Cretaceous European lissamphibian assemblages at the family level. The transition from the Jurassic to Cretaceous lissamphibian fauna in Europe is characterised by the retention of the albanepetontid <i>Celtedens</i> and, possibly, by extinction of stem karaurid salamanders.</p>
