DescriptionColumbian mammoth discovered with Clovis points.jpg |
English: Mammuthus columbi (Falconer, 1857) - Columbian mammoth skeleton from the Pleistocene of Colorado, USA. (CM 12066, Carnegie Museum of Natural History, Pittsburgh, Pennsylvania, USA)
From museum signage: "Relatives of this mammoth migrated to North America from Asia during the Pleistocene Epoch. The Columbian Mammoth lived in warm grasslands in the southeastern part of the continent, ranging as far south as Central America. This individual was found along with many others in the gravel deposits of Colorado’s Platte River. Discovered with it were stone spear points - so-called Clovis Points - that were made by Paleoindians. This was the first definite evidence that mammoths were hunted by humans in America. " Classification: Animalia, Vertebrata, Mammalia, Proboscidea, Elephantidae Locality: Dent site (alluvial fan gravel deposit near the old Dent railroad station, next to the South Platte River), near the town of Milliken, southwestern Weld County, northern Colorado, USA See info. at: en.wikipedia.org/wiki/Columbian_mammoth and en.wikipedia.org/wiki/Dent_Site |
