Fossilized Mako shark teeth span a large range of time, primarily found in deposits from the Oligocene through the Pliocene epochs.

• Age Range: The most commonly found extinct Mako shark teeth, particularly from species like Isurus hastalis (often called the Broad-toothed Mako, and now sometimes classified as Cosmopolitodus hastalis), are typically dated between 30 million and 1 million years ago. This covers the Oligocene, Miocene, and Pliocene periods.

Because sharks constantly shed their teeth, and their cartilage skeletons rarely fossilize, these durable teeth are the most common record of the Mako shark's long evolutionary history.
