Extract

The genus Tapirus of all the recent Ungulata, is the most discontinuous in its distribution over the Earth's surface. Wallace, in his great work on the “Geographical distribution of Animals,” in referring to extinct Tapirs, remarks: “the singular distribution of the living species is thus explained, since we sea that they are an old world group, which only entered the American continent at a comparatively recent epoch.” He reaches this conclusion by the fact that at the time his work was written (1876) the only known remains of the Tapiridse in America were from the Post-Pliocene deposits.
