HABITAT LOSS AND HUMANS: CAUSE OF MASS EXTINCTIONS
IN THE FAUNA OF NORTH AMERICA
Approximately 11,000 years ago 73.3% of the megafauna, or animals that weigh over 100 kg., that roamed across North America went extinct, this equaled about 35 different kinds of animals. What sets this extinction apart from past extinctions is that the animals that died were mainly large terrestrial animals with very few marine or plant extinctions. Another strange thing is that many of the animals that did go extinct had survived previous interglacial periods with little disturbance.
Some examples of the megafauna who lived and died in North America at the end of the last ice age:
Giant Sloth American Camel
Giant Bison Bush Oxen
