“…Thus, the Gran Chaco specimen is the first record of Notiomastodon platensis from Bolivia and, although N. platensis records are abundant in South America, from lowlands to highlands (see Ficcarelli et al, 1995;Ferretti, 2008;, the two South American proboscidean species were never recorded in the same locality. The Gran Chaco N. platensis record is 180 km from the Tarija valley, the locality with the most significant C. hyodon records in South America.…”

-Proboscideans are common constituents of the Quaternary megafauna in South America and their remains have been recovered over the entire continent; however, the records of Notiomastodon platensis are unknown in Bolivia, Guyana, French Guyana and Suriname. In this study, we describe the first record of Notiomastodon platensis from Bolivia. A N. platensis upper tusk was found in the Gran Chaco province, Tarija, a region widely known by its Quaternary megafauna, especially of the proboscidean Cuvieronius hyodon. The geographic distribution of both proboscideans suggests that they did not occur in sympatry, probably due to competitive exclusion (similar mixed-feeding diet) during the middle-late Pleistocene.

“…La población de Bolivia es considerada por algunos investigadores como una especie de Cuvieronius diferente a C. hyodon (e.g. Ficcarelli et al, 1995), y más aún, la morfología de la ulna (ver Ficcarelli et al, 1995) en Haplomastodon (Stegomastodon sensu lato) es la misma que la de la pieza de Tarija, lo que sugiere, apoyado en que la morfología debe ser conservativa, la mezcla de materiales de distintos géneros en esas localidades sudamericanas. Otros autores consideran que no hay claras diferencias entre estas formas y que todo es parte de la variabilidad poblacional que se da en los gonfoterios (Alberdi, com.pers.…”

Se describen los restos de Cuvieronius hyodon, recuperados en el estado de Colima, enfatizando las características que permiten diferenciar los restos postcraneales de este gonfoterio de los de otros proboscidios mexicanos. El estudio del esqueleto permitió identificar cuatro individuos adultos, dos hembras y dos machos, e interpretar las diferencias en talla como consecuencia del dimorfismo sexual secundario. El análisis bivariante comparativo de los terceros molares inferiores ubicó la talla de la población de Colima como intermedia entre las poblaciones mexicanas (167-215 mm de longitud del molar), aunque es pequeña comparada con las poblaciones sudamericanas (197-243 mm). La distribución de las localidades de Cuvieronius en el país sugiere que la dispersión del grupo se efectuó a través de las tierras bajas de ambas vertientes, de manera similar a lo que se observa en especies actuales de afinidad tropical.

“…However, the name Mastotherium hyodon had priority over the name M. andium proposed by Cuvier (1824). Nevertheless, the isolated teeth described by Cuvier (1806Cuvier ( , 1824 and Fischer (1814) are not diagnostic to any bunodont proboscidean at the specific level, based on recent diagnoses, and they could represent either of the South American taxa, including the same taxon (Mastotherium hyodon and/or Mastodon humboldtii; Ficcarelli et al, 1995;Ferretti, 2008;Lucas, 2008). Lund (1839) mentioned some proboscidean remains from Lagoa Santa, Minas Gerais State in Brazil, but he gave no classification, description or illustration of the specimens (a nomen nudum), and Lesson (1842) listed only the name "Mastodon brasiliensis Lund".…”

American Biotic Interchange. They are not sister-taxa e Cuvieronius hyodon is sister-taxon of Rhynchotherium, and this clade is closer to Notiomastodon platensis than to the other proboscideans, supporting the hypothesis of independent origins. Notiomastodon platensis has a continuous record from the Early Pleistocene to Early Holocene, when it became extinct, probably due to synergy of human impact and climatic changes during the Pleistocene/Holocene transition. In contrast, extinction of Cuvieronius hyodon happened much earlier, and it was not related to the terminal Pleistocene event that lead the extinction of selected megafauna in South America, including Notiomastodon.
