Also known as Pygmy Mammoth, Channel Islands Pygmy Mammoth, Santa Rosae Mammoth
Pygmy mammoths evolved through insular dwarfism on the prehistoric super-island of Santa Rosae off the coast of Southern California, shrinking to a fraction of the size of their ancestral mainland stock. Their reduced stature, shortened limbs, and agile build allowed them to traverse steep coastal bluffs, rocky ravines, and dense scrub with remarkable ease. They vanished at the end of the Pleistocene, roughly 13,000 years ago, coinciding with rising sea levels, changing vegetation, and the arrival of the earliest human hunters.
