Ancient shark relatives from the Pennsylvanian Period evolved some puzzling jaw structures that sometimes curved outward, giving the appearance of two saw blades curving away from each other. That’s why scientists describe them as “tooth whorls.”
Discovered by an excavation crew in 1926 on the bank of the Ohio River near Golconda in Pope County, this Wooly Mammoth (Mammuthus primigenius) specimen didn’t come quietly. Illinois State Museum Director Aljah R. Crook worked with the crew on scene to recover as much of the Mammoth skeleton as possible.
In what might have been the most successful college field trip of all time, Lincoln College freshman Judd McCullum discovered the tusk of a Wooly Mammoth (Mammuthus primigenius) during a biology lab at the college’s Creekside Field Station in 2005. McCullum discovered the 12-foot-long tusk while conducting a freshwater mussel survey. The mammoth may have been one of the last of its kind in the region. Carbon-14 dating determined the animal died about 11,500 years ago, well after the glaciers had retreated from Illinois.
This canary’s name is Nicodemus. He belonged to an Illinois woman in the 19th century. Nicodemus was free from his cage and sitting on a window sash one day when someone threw open the sash and smashed him. His owner was so distraught that she had him stuffed and mounted, and he sat on display in the family parlor for the next several decades.
