Phillipsiidae is a family of proetid trilobites, the various genera of which comprise some of the last of the trilobites, with a range that extended from the Kinderhookian epoch of the Lower Mississippian, to the end of Changhsingian age at Permian-Triassic extinction event in the latest Permian period.
Phillipsiidae is sometimes defined as a subfamily, "Phillipsiinae," and usually placed within the family Proetidae. Jell & Adrain (2003) went so far as to lump Phillipsiidae into the family Proetidae, however other workers since like Lerosey-Aubril and Feist (2005) have continued to recognize Phillipsiidae as a distinct and separate family within Proetida.
Subfamilies The following genera are included, divided among six subfamilies:
No subfamily Phillipsia (type genus) Breviphillipsia Comptonaspis Griffithidella Hesslerides Kollarcephalus Nunnaspis Phillibole Piltonia Subfamily Archegoninae Archegonus Hildaphillipsia Subfamily Bollandiinae Bollandia Kathwaia Neoproetus Subfamily Cummingellinae Bedicella Cummingella Paraphillipsia Persiax Subfamily Cyrtosymbolinae Carbonocoryphe Cyrtosymbole Subfamily Ditomopyginae Acanthophillipsia Acropyge Ameropiltonia Ameura Ampulliglabella Australokaskia Anisopyge Delaria Ditomopyge Hentigia Iranaspidion Jimbokranion Malchi Microphillipsia Novoameura Planokaskia Permoproetus Pseudophillipsia Simulopaladin Timoraspis Triproetus Vidria Subfamily Thaiaspidinae Thaiaspis Thigriffides Subfamily Weaniinae Doublatia Endops Nipponaspis Weania
