Pleistocene Megafauna

Pleistocene Megafauna

During the Pleistocene Epoch large animals lived that are called Pleistocene megafaunas. Most of these animals were extinct during the last glacial retreat around 10,000 years ago. Here are a few animals that lived during that time period, and some even lived in Indiana!

Dire Wolf


The Dire wolf is the largest canid to have ever existed (Canis Dirus P.1). It was about 5 feet long, and it weighted 125 or more pounds. The Dire wolf is somewhat bigger than the modern day Gray wolf, but the Dire wolf has larger and more massive teeth. Another difference is the Dire wolf had much shorter legs than the modern day wolves. The wolf was extinct around 16,000 years ago because of the extinction of its prey.


Woolly Mammoth
 
Woolly Mammoth is a specious of mammoth that has a common name “Mammothus”. The closest relative to this huge monster is the Asian Mammoth. The mammoth is the same size as the modern day elephant. The mammoth could live during the ice age, because its whole body was covered with thick fur. It lived in the Mammoth Steppe in Eurasia and North America. The animal was extinct about 4,000 years ago due to climate change, and human hunting. (Woolly Mammoth P.1)

Wild Horses
 
The wild horse is not the modern day wild horse. This ancient animal originated around 1 to 2 million years ago in North America. The wild horse lived in Asia, Europe, and Africa. The animal died off around 13,000 years ago, and I believe it was due to the climate change. (Kirkpatrick P.1)
The Bison Antiquus is sometimes called the “ancient bison”. It was a large herbivore. It’s the direct ancestor of the American Bison. The animal is 15 to 25 percent larger than the modern day bison. The bison was about 7.5 feet tall, 15 feet long, and weighed at 3,500 pounds. The animal died off around 10,000 years ago. I don’t believe these animals became extinct; I believe they went to evolution to become the modern day American Bison. (Bison Antiquus P.1)
The giant beaver was the largest rodent in North America. It lived in Illinois and Indiana. The rodent was as big as a small bear. The front teeth were about 6 inches long. As you might think these beavers might have built huge dams, but believe it or not they had nothing to do with dams. These creatures lived around 12,000 years ago, and it is said that the climatic change made the animal go extinct. (Hauser P.1)
The Stag-Moose was a weird looking animal; it looked like it was a cross between an elk and moose. The animal was larger than the modern day moose. Their antlers were more complex than the modern day moose. It was extinct around 11,500 years ago, due to the climate change and human hunting. Also if you wish to see how this animal really looked you can visit the Illinois State Museum. (Stag-moose P.1)
