Several Native American cultures were known for the large mound platforms they constructed. These mounds served primarily as foundations for erecting important community buildings. The Kincaid Mounds of Illinois date from 1050 to 1400 and featured some of the largest mounds of the Mississippian Culture.

Ambystoma tigrinum - The markings of an eastern tiger salamander varies in coloration from one region to another; the more common color being brown and bright yellow markings resembling a tiger. They are the largest terrestrial salamander in the world, growing to maximum lengths of 35 centimeters. The tiger salamander is born in an aquatic environment and returns to the water only for breeding purposes. Adult tiger salamanders are rarely seen since they only venture out of their burrows at night to forage for food.
