Columbian mammoth
Apart from its larger size and more primitive molars, the Columbian mammoth also differed from the woolly mammoth by its more downturned mandibular symphysis; the dental alveoli (tooth sockets) of the tusks were directed more laterally away from the midline. Its tail was intermediate in length between that of modern elephants and the woolly mammoth. Since no Columbian mammoth soft tissue has been found, much less is known about its appearance than that of the woolly mammoth. It lived in warmer habitats than the woolly mammoth, and probably lacked many of the adaptations seen in that species. Hair thought to be that of the Columbian mammoth has been discovered in Bechan Cave in Utah, where mammoth dung has also been found. Some of this hair is coarse, and identical to that known to belong to woolly mammoths; however, since this location is so far south, it is unlikely to be woolly mammoth hair. The distribution and density of fur on the living animal is unknown, but it was probably less dense than that of the woolly mammoth due to the warmer habitat. An additional tuft of Columbian mammoth hair is known from near Castroville in California, the hair was noted to be red-orange and was described as being similar in colour to a Golden Retriever.
