Markings on the bones shows these animals were butchered by recent human ancestors. This helps place a landmark with a date for the evolution and migration of Homo sapians living in North America during the Pleistocene.

This was done by first determining that 34.75% of the original C14(Parent Isotope) had changed to N14 through beta decay.

Then using (Figure 2) it was determined that 2.53 half lives had elapsed since the mammoth died.

If Our School Was Here Over 10,000 Years Ago, What Would Our Mascot Be?

In 1936, work crews channelizing the outflow creek from Mud Lake encountered roughly 20 leg and foot bones of a Woolly Mammoth.

Illinois is not the typical habitat of large elephant-like animals, so why do we find mammoth bones in Illinois and what are these strange lacerations on them?

Since thehalf-life of C14 is 5,730 years, a little multiplication yields the age of the mammoth 2.53 x 5,730 = 14,470 years old (Tarbuck& Lutgens, 2005).

Figure 5 –The mammoth fossils were determined to be from the Late Pliestocene Epoch of the Quaternary Period (orange outline)Figure 1.Putting an actual date on these bones found places this environment roughly 14,000 years ago.Knowing the average decay rate of C14 helped geologists place a numerical date on these mammoth bones.The cross section of the Mud Lake site displays what once was a swampy environment that came after a site that was near the terminus of a retreating glacier.This shows climate in the area was once much different than what we are used to today.Had Maine East been located in the area nearly 10,000 years ago, we may have changed from Demon Pride to Mammoth Pride. Parent Daughter isotope curves plotted over several half lives.
