On the trail of the giant prehistoric sharks:

A chat with fossil hunter William “Bill” Eberlein: William “Bill” Eberlein has been diving since 1986, and he's all about teeth. Not his own, but the teeth of large creatures long extinct. You see, Bill is an underwater fossil hunter who dives into the coastal waters of Georgia to salvage fossilised teeth from the bottom. Recently, he discovered a mastodon jaw, causing a stir in academia and the media.

I was doing my normal dive when I felt what I thought was a fossilised log but when I felt the molars, I knew I had found something very rare,” said Bill. The jaw had been hidden under the mud, so it had to be dug out. Bill described the jaw as being really heavy to bring up 15 metres to the surface, as it weighed about 60 pounds.
 
Mastodons have been extinct for more than 12,000 years. They were mammoths which stood up to three metres high and weighed more than 6,000 kilogram’s. Enormous but cuddly in appearance, these aggressive creatures roamed the Earth in search of food. The mastodon jaw that Bill salvaged had two fist-sized teeth complete with the roots. The teeth were loosely seated in the jaw, but could be removed. It was an impressive find.

Today, Bill mostly focuses on the teeth of the prehistoric giant shark called the megalodon. Measuring more than twenty metres long, they were as large as the sperm whales of today. Not to be messed with, these predators were so huge that a adult human could easily fit in the jaw, amid the hundreds of razor-sharp serrated teeth.

Bill has already recovered hundreds of megalodon teeth from the muddy and brackish waters of Georgia’s coast. His biggest discovery to date measures more than 17 centimetres high and 12 metres wide, weighing in at over a kilogramme. It had small serrated teeth along its flanks that made it the perfect megalodon tooth.

Every tooth is unique

Having taken up sport diving as a hobby, Bill went on to become a member of a search & rescue team, and then a NAUI instructor. After moving to Georgia in south-eastern United States, he accompanied a fossil diver into the murky coastal waters of Savannah one day, where the freshwater river met the saltwater of the ocean. “From the onset, I was intrigued. After I found my first megalodon tooth, I got hooked. I drove every chance I got,” said Bill, of his early days in the field. By early 2001, he had collected so many megalodon teeth that he decided to sell some of them. Seven years later, he resigned from his job as an IT teacher at a technical school and devoted himself fully to the search for underwater fossilised teeth.

He set up his website (www.megateeth.com), together with an online shop where those interested can browse his range of megalodon teeth and buy one for about US$150 onwards. The finer pieces are sent to museums worldwide, and these can cost more than US$1,000 each. Every tooth is unique and is individually certified by Bill. Most of the teeth have been salvaged by Bill and have not been repaired or modified, unlike most of the other megalodon teeth being sold online or at eBay.

Bill dives at depths of 10 to 20 metres, mostly amid zero visibility. The 50-watt lamp he carries can barely allow him to read his instruments. Imagine being in that situation for nearly one and a half hours, which is the duration he sometimes remains underwater.

"This is not for beginners. While you’re looking for the remains of the dead, you’re also bumping into what’s alive. Accidentally grabbing a stingray is pretty normal, and I fear them more than I do sharks. They come flying out of the mud with their barbed tail thrashing around. When you blindly grab something and it moves, you jump back as far and as fast as you can. […] What I really hate is when I grab what I think is the smooth enamel surface of a megalodon tooth, and it turns out to be the shell of a blue crab offering a painful pinch,” said Bill, with a laugh.

Bill has seen it all and so knows how to react in all circumstances. He has even encountered sharks that bump into him in the darkness as they search for prey in the coastal waters. In a relaxed tone, he continued, “Tiger, hammerhead and bull sharks visit these waters, even alligators. Thankfully, these carnivores seem to have no interest in me.

In addition, the currents make the dive an unpredictable experience, as they may transport Bill to another part of the river.  Boats and ships also pose a danger, as he explains: “Underwater, you can hear them above you, but it is impossible to tell how close they are. The sound is distorted, and, for this reason, I must use extreme caution when I surface.” And if one loses sight of the boat in a strong current and additionally it is necessary to add a safety decompression stop; the whole operation isn't all that relaxed.

To date, for almost ten years, Bill has been indulging in a hobby that has become his profession. People often ask him how he remembers when it is time to ascend to the surface when he cannot read his instruments. “I surface when it gets hard to breathe,” is his casual response. However, you never know exactly what William “Bill” Eberlein is thinking when he says this with a broad smile on his face.
