(2008), Williams and Kirk (2008); to Tarsiiformes by Szalay (1976), Hooker (1986), Carroll (1988), Bown and Rose (1991), Gingerich (1993), Beard et al. (1994), Rasmussen (1996), Gunnell and Miller (2001), Muldoon and Gunnell (2002), Bajpai et al. (2005), Hooker (2007), Rose et al. (2009); to Euprimates by Silcox et al. (2010); to Omomyiformes by Burger (2010); to Primates by Rose et al. (2012), Morse et al. (2019), Korth et al. (2022); and to Omomyoidea by Atwater and Kirk (2018), Perry et al. (2023).
