In honor of International Museum Day, the KU Natural History Museum invites you to its Pop Up Science event all about fossil shark teeth! Thanks to our friends at the Aurora Fossil Museum in North Carolina, visitors can use a sieve to search through sediment and find fossilized shark teeth that are about 15 to 5 million years old, including teeth of the famous C. megalodon shark! Plus, learn about the differences between fossil shark teeth preserved in eastern Kansas vs. those of coastal North Carolina.
