JoinAfter the Bell: Beachcombing for fossils
If you have ever taken a field trip to a natural history museum or an aquarium, you may have noticed in the gift shop a display of fossil shark teeth that can be as old as 65 million years for sale. Where did these teeth come from? How are the ages of these teeth known? Can I find such teeth on my own and, if so, where? These are questions that people of all ages often ask while marveling at these beautiful relics from eons past, and these are the questions we answer in this month's After the Bell column.
