8. A Mammoth’s Tusk
Construction sites usually require several types of specialists on-call. They rarely, however, need a paleontologist. This site was an exception to that rule. In February 2014, paleontologists were called to a place where construction workers found a fossilized mammoth tusk measuring around 8.5 feet long.
The tusk is estimated to be approximately 60,000 years old and is on display at the Burke Museum of Natural History and Culture in Seattle, Washington. One of the Vice Presidents of the construction project has also confirmed that the planned building schedule will be pushed back, as the significance of the discovery is more important than the building project.
