Teilhardina americana and
T. crassidens were originally named as species of
Teilhardina, usually considered a member of Omomyidae. However,
phylogenetic analysis by Ni et al. (2004) recovered
Teilhardina as
polyphyletic, with
Teilhardina belgica and
T. asiatica nested as the basalmost
haplorrhines, and
T. americana and
T. crassidens being recovered as
anaptomorphine omomyids (and thus more closely related to the
tarsiers than to
simians).
Teilhardina crassidens was later referred to the genus
Baataromomys by Ni et al. (2007). A paper by Morse et al. built upon the cladistic results of Ni et al. (2004) by recognizing
T. americana and
T. crassidens as belonging to a new genus, which they named
Bownomomys. ==References==
