Shell Specimen: Shark
“Shelling” is a fun for professional scientist and amateurs alike. Most sea shells are made by snails and clams, but sometimes beachcombing can find shark’s teeth washed ashore. Unlike humans, sharks have a stacked supply of replacement teeth ready to move forward when one is lost while feeding. This is why shark teeth are so abundant in the fossil record as well.
