Fries, C. Jr., Hibbard, C. W. & Dunkle, D. H. Early Cenozoic vertebrates in the Red Conglomerate at Guanajuato, Mexico. Smithsonian Miscellaneous Collections , 1– Introduction. Alfred Dugès () began the formal study of wild mammals in the state of Guanajuato, Mexico. After his death the subject remained virtually forgotten for almost a hundred years. The rodent family Geomyidae is native to America. It comprises six extant genera with 40 species distributed from Saskatchewan, Canada to northern Colombia. Two subfamilies are included in the family, the extinct Entoptychinae, with a fossil record ranging from the late Oligocene (Arikareean) to the middle Miocene (Barstovian) and the Geomyinae, with a chronological range from middle Miocene. This species was first identified in and was fully described by John L. Lecont in Another new peccary was described in and given the name Platygonus leptorhinus, but this animal was later determined to be synonymous with P. compressus. The genus name, Platygonus, is derived from the Greek language, literally meaning "flat head".The species name, compressus, is a Latin word.
