Luzocephalus is an extinct genus of temnospondyl from the Early Triassic of Russia (Vetluga Series, Kasnyye Baki horizon) and Greenland (Wordie Creek Formation). It is usually regarded as a member of the family Lydekkerinidae, although it has also been placed in the family Trematosauridae.{{cite journal |last=Damiani |first=R.J. |author2=Yates, A.M. |year=2003 |title=The Triassic amphibian Thoosuchus yakovlevi and the relationships of the Trematosauroidea (Temnospondyli: Stereospondyli) |journal=Records of the Australian Museum |volume=55 |issue=3 |pages=331–342 |url=http://web1.australianmuseum.net.au/Uploads/Journals/17964/1388_complete.pdf |doi=10.3853/j.0067-1975.55.2003.1388}}{{Cite journal | last1 = Dias-Da-Silva | first1 = S.
