The Dwarf mammoth, Channel Islands mammoth or Mammuthus exilis is an extinct species of dwarf elephant descended from the Columbian mammoth (M. columbi) of mainland North America.
This species became extinct during the Quaternary extinction event in which many megafauna species became extinct due to changing conditions to which the species could not adapt. A case of island or insular dwarfism, from a recent analysis in 2010 it was determined that M. exilis was on average, 5.6 feet tall at the shoulders and 1,680 lbs. in weight.
Channel Islands of California Mammoth remains have been known on the northern Channel Islands of California since 1856. They were first reported in scientific literature in 1873. In 1994 the National Park Service called in scientists to inspect an uncovered, unidentified skeleton found on the northeast coast of Santa Rosa Island.
They found bones of the axial skeleton of a large land vertebrate and decided to excavate and dig up the skeleton. They recovered 90 percent of a mature male dwarf mammoth or Mammuthus exilis skeleton. The dwarf mammoth was about 50 years old when it died. The small bones were preserved in life position, which represented that it had died where it was found rather than being scattered around the island. The bones were returned to the Santa Barbara Museum of Natural History.
After the discovery of the Dwarf Mammoth or Mammuthus exilis skeleton, a pedestrian survey of the island was started, which resulted in the discovery of 160 new locations of dwarf mammoth remains, the vast majority being found on Santa Rosa Island.
This was the first discovery of a nearly complete specimen of the dwarf mammoth or Mammuthus exilis. Fortunately enough, the skeleton of the dwarf mammoth was only missing a foot, a tusk, and a couple of vertebrae. The remains were covered by a sand dune, which prevented the bones from scattering and kept them intact.
