Hunting for shark teeth in Central Florida

I got a tip a few weeks back from someone who told me to look for shark teeth in the creeks around Gainesville.

The teeth are there, they said. You just have to know where to look.

So, I set out to find them. And find them I did.

Hogtown Creek in Loblolly Woods Nature Park

I went to Loblolly Woods Nature Park, which is one of many parks that protects Hogtown Creek, the small, swift brook that cuts across the city.

Loblolly Woods has a few miles of hiking, biking and jogging trails and, likely because of how convenient the it is, the park gets a lot of use.

But the star of the show is the creek. The ages-old creek plays a vital role in Gainesville’s ecology, and it ultimately flows into the aquifer from which Gainesvillians draw their drinking water.

The creek has a mostly sandy bottom, but pebbles gather in the bends and where the elevation of the creek bottom changes. Grab a handful of pebbles and you’ll be surprised what you find.

In 15 mintues of looking, I found about 10 sharks’ teeth. Most were small (1/4 inch, maybe), but some were of a decent size. All of them were very, very old.

Like, 10 million years old, according to the experts.  The creeks in Gainesville cut into a phosphate layer under the soil, which formed when central Florida was first rising out of the ocean.  That layer holds the fossilized remains of aquatic animals and land animals – saber teeth have also been found in the area, for example.

In fact, Gainesville is one of the best places in the state to look for fossils, especially shark teeth.  Hogtown Creek, Rattlesnake Creek, and many of their tributaries are littered with shark teeth.

The best time to go for a hunt is after a heavy rain, when the high water levels recede and leave less-dense fossils on top of the more-dense rocks.  The best places to look are in the bends of the creek, where small pebbles tend to accumulate.

Take care to leave the creek in a better condition than you found it.  Don’t step on plants, don’t dig and take out any garbage you come across.
