.82" Colorful, Fossil Tiger Shark Tooth - Bone Valley, Florida

Here is a colorful example of a fossil tooth from Galeocerdo cuveri, a tiger shark. It was collected in the Bone Valley Region of Florida, an area known for colorful preservation of fossil teeth. Comes in an acrylic display case.

Galeocerdo, which means, "fox shark," is the genus of all Tiger sharks and Tiger-like sharks, both living and extinct. Tiger sharks are a genus of Requiem sharks (migratory, warm sea, live-bearing sharks) that have hunted the temperate and tropical seas since the Eocene epoch.

These fearsome predators are nomadic and often spend solitary lives, joining other sharks only for procreation. Tiger sharks are sometimes referred to as "garbage sharks." This moniker refers to their disposition towards eating anything in their path.

The earliest Galeocerdo species in the fossil record is G. latidens from the Eocene. The more common fossils that come out of the American southeast are of G. aduncus, from the Oligocene, and G. cuveri, which originated in the Pliocene and persists today as the only living species of Tiger shark.

The best way to identify Galeocerdo teeth by species is to look at the size of the tooth and the complexity of the serrations. Generally, larger teeth with more complex serrations point to a shark from a time closer to the present. For example, a tooth from G. cuveri is much bigger and more serrated than a tooth from G. aduncus or G. latidens.
