Rafael Acuña-Mesén, Elmer García-Díaz
A lower mastodont molar was found in Nacaome river, Nicoya, Guanacaste, Costa Rica. It is a Pleistocene specimen of Cuvieronius hyodon. C. hyodon and Haplomastodon waringi, mountain and savanna mastodonts respectively, have been found in the same place. This evidence and the dental morphology suggest that they were seasonaly simpatric species with different alimentary niches. Probably H. haringi fed on savanna or prairie plants (very ligneous with high silica concentration, e.g. Cyperaceae ) whereas C. hyodon consumed softer plants (the enamel is less damaged).
