Taxonomy
Microsyopidae was named by Osborn and Wortman (1892). It is not extant. Its type is Microsyops.
It was corrected as Microsyopsidae by Hay (1930).
It was assigned to Cheiromyoidea by Wortman (1903) and Wortman (1903); to Proglires by Hay (1930); to Plesiadapiformes by Rose and Bown (1982); to Paromomyoidea by McKenna and Bell (1997); to Microsyopoidea by Gunnell (1989) and Hooker et al. (1999); and to Primates by Bloch et al. (2007), Silcox et al. (2010) and Rose et al. (2012).
