Even casual observers of poker can point out Greg “Fossilman” Raymer.

They might not know the name, but they know the specs.

Raymer wears a pair of trick glasses when he’s at the table, glasses with holographic images of eyeballs and dinosaurs that change depending on the viewing angle.

They must be working. Raymer won the 2004 World Series of Poker main event and its unprecedented $5-million jackpot.

Why “Fossilman”? Raymer collects fossils and uses them as card protectors, which also explains the dinosaur glasses.

He could probably buy his own dinosaur now that he’s $5 million richer. National exposure on ESPN has also given Raymer the chance to promote Internet poker sites, which is how Raymer got into the WSOP to begin with.

Raymer, a native of Lansing, Mich. now living in Stonington, Conn. with his wife and daughter, graduated law school at the University of Minnesota.

He started playing poker there, although not for much money. Instead, Raymer played blackjack on reservation casinos to help him through college, and then picked up poker again after getting his first job as a lawyer in Chicago.

Thanks to the Internet, Raymer was able to hone his game in short order.

“Fossilman” has yet to duplicate his success from 2004. Poker aficionados are quick to point out flaws in Raymer’s strategy, and ESPN’s detailed coverage of the WSOP has given Raymer’s detractors plenty of ammunition.

Raymer has a tendency to gamble with going all in, sometimes even doing so before the flop. But he has a knack for timing, and he’s disciplined enough to know when to fold ‘em.
