Genera
  • See text

Proetidae is a family of proetid trilobites. The first species appeared in the Upper Ordovician, [1] and the last genera survived until the Middle Permian . However, if the closely related family Phillipsiidae is actually a subfamily of Proetidae, then the proetids of Proetidae survive until the end of the Permian, where the last perish during the Permian–Triassic extinction event. [2]

Genera

Proetidae ostensibly contains these following genera, though many may be placed in Phillipsiidae if the latter is, indeed, a distinct family. [3]
