Icy Illinois Hero

Icy Illinois

Burrrrr! It was COLD in Illinois!

Grab a hat and coat because this trip back in time is to the Rockford Ice Age! From Mammoths, to Giant Sloths, to Giant Beavers, and the humans that hunted them we will journey to a time that looked quite different than today. We will look at Ice Age survivors we can find in our area today, such as wolves and beavers, and compare them to other animals of the Ice Age that didn't survive, such as the saber toothed cats and dire wolves. Compare their skulls, and learn what made this time so unique! Students will touch teeth, examine fur, and learn how glaciers shaped the land we see today.

Key Concepts:

Ice Age, survival traits, early human hunting, glaciers, Illinois landscape, Illinois history


Asking questions, making observations, analyzing and interpreting data

Discover Card
Ice Age
Castoroides ohioensis

Giant Beaver

A huge beaver found throughout most of North America. It was much larger than today’s beaver and approached the size of today's black bear. Some studies estimate that the largest giant beaver could reach almost 300 pounds! (1.4 million–11,000 years ago)

Ice Age
Smilodon fatalis

Saber Tooth Cat

Notice the large forearms on the Smilodon skeleton. They are massively built and were used to subdue their prey. Their long canines, or “sabres”, helped to deliver a fatal blow to the neck of the animal.

Megalonyx jeffersonii

Jefferson’s Ground Sloth

Sloths in Illinois! This mammal stood as tall as 10 feet, had a large, blunt snout, long claws, and teeth with an outer layer of dentine rather than enamel. In life, this sloth was likely covered in thick hair and lived in woodlands and forests.
