In honor of The Discovery Channel’s Shark Week, here are some common questions asked about shark teeth, and some meaty facts to sink your teeth into.
Q. Why are some shark teeth black and others are tan?
A. The color of a fossil shark tooth is dependent upon the sediment in which it settled. As minerals slowly replace the calcium in the tooth, it changes to the color of the minerals. Color does not necessarily indicate age in a shark tooth fossil. It usually indicates the region from which the tooth was collected. Our fossilized shark teeth are collected from Morocco.
