The Columbian mammoth (Mammuthus columbi) is an extinct species of mammoth that inhabited North America from southern Canada to Costa Rica during the Pleistocene epoch. The Columbian mammoth descended from Eurasian steppe mammoths that colonised North America during the Early Pleistocene around 1.5–1.3 million years ago, and later experienced hybridisation with the woolly mammoth lineage.
The largest known species like Mammuthus meridionalis and Mammuthus trogontherii (the steppe mammoth) were considerably larger than modern elephants, with mature adult males having an average height of approximately 3.8–4.2 m (12.5–13.8 ft) at the shoulder and weights of 9.6–12.7 tonnes (21,000–28,000 lb), while exceptionally large ...

An amateur fossil hunter discovered a 20,000-year-old Columbian mammoth tusk, the first intact find in Mississippi, revealing new insights into the state's prehistoric era.
South Dakota is a bit further south than the woolly mammoth's range, which is why most of the site's mammoths are the Columbian species. For decades, researchers working on the site thought the ...
The massive Columbian mammoth, a proboscidean related to modern elephants that lived during the Pleistocene Epoch, could grow to be 15 feet at the shoulder and weigh over 10 tons. The discovery of ...
[4] [5] Invertebrate discoveries include several species of clams, snails, and slugs. [6] [7] The majority of the mammoth remains have been identified as those of Columbian Mammoths, although the remains of three Woolly mammoths have been found as well. [8] Mammoths that slipped into the sinkhole found it difficult to escape.
† Columbian mammoth [52] † Mammuthus columbi: At least 36 individuals. A large species of mammoth. The largest individual found at La Brea, nicknamed Zed, was unearthed in 2006 and had tusks 3.16 m (10.4 ft) long (measured along their outer curve). Zed is also the most complete mammoth found in the tar pits, preserving 80% of the bones. [53]
