Talk:Amphipteryx

Monotypic family Amphipterygidae?
per GBIF Amphipterygidae is not monotypic. Per GBIF eg Pentaphlebia belongs also here. Some sources says that also exists monotypic Pentaphlebiidae. Maybe Pentaphlebiidae is synonym of Amphipterygidae?--Estopedist1 (talk) 22:48, 16 June 2021 (UTC)
