Protostrigidae is a prehistoric family of owls which occurred in North America, Europe,[1] and Asia[2] during the Eocene and early Oligocene periods.[1] Genera include Eostrix , Minerva , Oligostrix ,[1] and Primoptynx. [3] In 1983, Cécile Mourer-Chauviré demonstrated that Protostrix is a junior synonym of Minerva .[1]
Protostrigidae characteristics include strong first and second toes as well as a widened medial condyle of the tibiotarsus.[1]
