32. 200,000-Year-Old Woolly Mammoth Bones
These contractors were lucky not to have to deal with human bones – instead, they discovered dozens of fossils from the Ice Age. Cornerstone Communities, a San Diego area contracting company, was developing a 636 unit subdivision in Carlsbad, California when they stumbled upon these ice age fossils. They’ve discovered skulls and partial skeletons from a bison, a woolly mammoth, an antique horse, and an antique turtle. California law does require a paleontologist be on-site when large amounts of dirt are being moved in case they find a fossil, so they quickly addressed the process in this situation.
