Taxonomy

''Nexuotapirus'' was erected in 1998. The type species, ''N. marslandensis'', was originally classified under '' Miotapirus''. The second species, ''N. robustus'', was originally placed in '' Protapirus'' but was also moved to ''Nexuotapirus'' based on comparable lower dentition.


Description

''Nexuotapirus'' shows both plesiomorphic and derived features compared to other early tapirs, making its exact relationship with them difficult to place. Primitive traits of the genus include less molar-like premolars and incisive foramina that extend posteriorly through the postcanine diastema, as well as a braincase that tapers towards the back. More advanced features include deep retraction of the nasal incision, nasal shortening, frontal shortening, and reduction of the supraorbital process, features comparable to the modern ''
