Cuvieronius hyodon (Fischer 1814)—Cuvier's GomphotherePleistocene distribution of Cuvieronius hyodon

Cuvieronius is described (Kurtén and Anderson 1980) as having a spiral enamel band on the tusks, molars with secondary trefoils, no cement, and without obliquity to the molar lophs.

Listed in earlier works as Cuvieronius tropicus (e.g., Morgan and Lucas 2005), specimens from the sites below are now considered to be C. hyodon (Morgan and Harris 2015).

In September 2010, Diana M. Alba of the Las Cruces Sun-News reported in the El Paso Times (19 September, p. 5B) the discovery of the skull of Cuvieronius in a "dirt mining pit near Mesquite", New Mexico. According to the account, the owner of the property, Eddie Binns, turned the specimen over to New Mexico State University. The skull apparently was damaged badly during removal. A photograph of the skull in situ accompanied the article. In view of the lack of further documentation, the occurrence is not given a site account nor listed below in the records of occurrence.
