Abstract

The trematosauroid family Lonchorhynchidae includes the subfamily Cosgriffiinae with the genera Cosgriffius Welles and Morovius gen. nov. The remaining valid taxa of the group are either placed in the subfamily Lonchorhynchinae proper or are considered as forms with less clear relationships. A new genus and species of Cosgriffiinae Morovius juliaromanorum gen. et sp. nov. is described based on fragments of the skull and lower jaw from the Zaplavnian Horizon of the Lower Triassic (Upper Induan substage) of Obshchii Syrt Highland. Possible relationships of lonchorhynchids with other long-headed Temnospondyli are briefly discussed.
