How to Identify Shark Tooth Fossils

Identifying fossils of shark teeth is not an easy task because of variations in appearance due to factors such as species, size and location of the tooth in the shark. Shark tooth fossils can be found on beaches and in the ocean through scuba diving or snorkeling. The sizes of the teeth vary from a few centimeters to as large as the palm of your hand. Finding and collecting shark teeth fossils is a hobby that is enjoyed by many due to its challenging nature.

Instructions

- 1
  Identify the shark tooth by first examining it closely. Notice the features of the tooth to decide whether it is smooth or rough, look at the color and porousness, and examine whether it has serrated or smooth edges. These characteristics will help determine whether the tooth is in fact a fossil, as opposed to a more recent specimen, and can help determine the type of tooth.
- 2
  Use pictures of shark teeth fossils to identify the type of tooth that you found. This is the most accurate way to determine what type of shark the tooth came from. For example, sand tiger sharks have a long smooth blade and a bilobed root. Looking at a picture of this is a much easier task than trying to identify it based upon this information. Websites such as the Biology of Sharks and Rays have pictures of fossils to guide you in identifying yours correctly.

  Confirm that your shark tooth is a fossil by checking with a professional individual or organization. If you live near a university, check with one of the biology professors. If not, the Geological Society of America may be able to help you confirm that your shark tooth is a fossil and not a more recent tooth.
