The type species Icticephalus polycynodon was named from the Tapinocephalus Assemblage Zone by South African paleontologist Robert Broom in 1915.[1] Specimens of Icticephalus have also been described from the Cistecephalus Assemblage Zone. Broom originally placed Icticephalus in the Scaloposauridae, a group of very small therocephalians. Most scaloposaurids are now thought to be juvenile forms of other therocephalians, and Scaloposauridae is no longer recognized as a valid grouping. Icticephalus and other former scaloposaurids are now classified as basal members of Baurioidea.[2] References1. ^{{cite journal |last=Benton |first=M.J. |year=1983 |title=Dinosaur success in the Triassic: a noncompetitive ecological model |journal=The Quarterly Review of Biology |volume=58 |issue=1 |pages=29–55 |doi=10.1086/413056}} {{Therocephalia}}{{Taxonbar|from=Q5986786}}{{paleo-therapsid-stub}}2. ^{{cite journal |last=Huttenlocker |first=A. |year=2009 |title=An investigation into the cladistic relationships and monophyly of therocephalian therapsids (Amniota: Synapsida) |journal=Zoological Journal of the Linnean Society |volume=157 |issue=4 |pages=865–891 |doi=10.1111/j.1096-3642.2009.00538.x}} 9 : Lopingian synapsids of Africa|Guadalupian synapsids of Africa|Baurioids|Therocephalia genera|Guadalupian synapsids|Guadalupian genus first appearances|Capitanian genera|Wuchiapingian genera|Lopingian genus extinctions |
