Besides sharks teeth, fossils of other marine creatures are also found in this area. Because millions of years ago most of Florida was under water, many fossils are found inland as well as on the beaches. State law prohibits digging without a permit however.

Identification of sharks teeth, which come in many different shapes and sizes, is relatively easy. All of the teeth in the mouth of a single type of shark are the same shape. They vary only  in size. The shape of the teeth of each species is distinct. Local book stores offer many books on the subject.

For millions of years, sharks have lived and died in the Gulf of Mexico. Dead sharks sink to the ocean floor where they are covered by layers of sand and silt. Over time, the cartilage of their bodies disintegrates. Water and storm action eventually sweeps the sand away, exposing the teeth. Some are washed up on shore with the changing tides and waves.

There are over three hundred and seventy distinct species of sharks. They are all cartilage based fish without air bladders. Dermal denticles, which are rough scales with tooth-like structure, cover their skin. Digestively, they have a special adaptation called a spiral valve which increases surface area in a rather short intestinal tract. Any further statement about shark biology or behavior would truly depend upon the species. Sizes range from the dwarf shark which rarely attains much more that half a foot to the sixty foot 40 ton whale sharks. Fortunately, the two largest species, whale and basking sharks, make their living filter feeding one of the ocean's smallest animals. These gentle slow-moving giants have hundreds of rows of hair-like gill rakers that cull plankton and tiny fish from the water flowing through their mouth.

The danger sharks pose to man:

Of hundreds of species of sharks, a handful are filter feeders deriving their nutrition from creatures smaller than several millimeters. Another substantial fraction live at depths not visited by man except within enclosed submersibles. Many more species are too small to pose a threat to man. Others have specialized adaptations that dictates the food sources they utilize: the long whip-like tail of the thresher; the impaling teeth of the sand sharks; the flat crushing teeth of the nurses. Remaining are a few dozen species that have the physique if not the inclination to feed on Homo Sapiens. Of all of these only three species are known to participate in unprovoked attacks on people: bulls, tigers, and great whites. Yet, we have developed an irrational fear of all sharks.

LEMON	CARCHARODON	DUSKY	SAND SHARK	BULL SHARK
	The largest and most impressive  of extinct sharks			Bull, Dusty, and Black-tipped are abundant, however they are difficult to distinguish from each other and from Lemon Sharks

	Mako teeth range from 0.25"  to 2" long and are one of the  more plentiful finds		Tiger shark teeth are usually less than 1"
