Pygmy mammoths! 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.

Given the location and level of deposition, the Columbian mammoth (M. columbi) or pygmy mammoth (M. exilis) would seem the most likely candidates—particularly the latter, since pygmy mammoths were native to the Channel Islands.

According to a new statistical study, mankind—not climate change—was the driving force behind the extinction of prehistoric behemoths like the wooly mammoth and the saber-toothed tiger. Evolving into a New Species Once on the island, the population of mammoths increased and, eventually, the food supply became scarce as the island decreased in size due to climatic changes – glaciers and ice sheets melting, and sea levels rising. Learn about the role of islands in the evolution of species. A cast of the pygmy mammoth skeleton is displayed in the Visitor Center.
