McDonald’s Fossil Prep Lab at Chicago Field Museum

The Chicago Field Museum has the McDonald’s Fossil Prep Lab where you can see Museum staff working to chip away stone to reveal nature’s treasure for scientific research.This working lab is fully equipped with tables that hold 2,000-pound rocks, microscopes, mini-jackhammers, mini-circular saws, and mini-sandblasters that shoot baking soda (strong enough to whittle away rock, soft enough to not damage precious fossils). A special exhaust system removes the resulting dust from the air.

See Sue’s gastralia, a group fossil bones so rare and unusual that scientists aren’t sure how they fit onto Sue’s skeleton. Among the most fragile of T. rex bones, they are most often incomplete, badly damaged, or missing altogether from fossil finds.
