Why do People Collect Shark Teeth?

The megalodon may be extinct, but the mega-obsessed will continue to search out anything related to this mysterious sea creature, and some collectors will pay top dollar for a rare megalodon tooth. In 2009, a group of paleontologists from the University of Florida in Gainesville discovered the fossilized remains of a megalodon nursery in Panama that was made up almost entirely of juvenile megalodon tooth fossils. Another suggests that that large predators like orcas and great whites could have preyed on juvenile megalodons, decreasing their chance for survival to adulthood. Great tips i always like to know new tech news from your blog.. I like this software. I never use this software, but have the other software that have a similar function. Megalodon expert Gordon Hubbell theorizes that the megalodon's diminishing food sources could have also been responsible for its demise -- as whale populations disappeared from tropical waters, the megalodon began to disappear, too. Proponents of the theory of megalodon's continued existence often point to eyewitness accounts to debate the possibility of the species' survival. Occasionally, a report will surface about a large, unidentified shark in the ocean, but those accounts have been mostly discounted as tall tales.

Most scientists, paleontologists and other experts believe from the fossil evidence that megalodon became extinct over 2 million years ago during the Plio-Pleistocene period, but some cryptozoologists and researchers think that this giant shark may still exist in the undiscovered depths of the ocean. Carcharodon megalodon, the megatooth shark, isn't just a favorite topic among science fiction fans and cryptozoologists (who study evidence of the existence of unverified species) -- it was a real, living shark that roamed the oceans around 1.5 to 20 million years ago. So what happened to the megatooth shark that knocked it from the top of the food chain to complete extinction? Experts estimate that the average adult female weighed between 50 to 100 tons (45 to 90 metric tons -- about the size of half of a blue whale) and could eat up to 2,500 pounds (1,136 kilograms) of food per day. Farah, Hodan. "U.S. Food Consumption Up 16 Percent Since 1970." Amber Waves. Since the skeleton of a shark is primarily made up of cartilage, which disintegrates over time, the only megalodon remains we've discovered are serrated teeth and vertebraelike centra.

Megalodon fossils have been discovered far and wide, from Japan to the United States, so researchers conclude that megalodon was an intercontinental species, living all over the world's ancient oceans. That's over 500 pounds (227 kilograms) more than the average American eats in an entire year. Because sharks are cold-blooded, each year they get growth rings on their vertebrae with the changing of the seasons, just as a living tree does. The color and width of the rings also help determine growth rate; wide, light rings indicate a faster growth than narrow, video shorts dark rings. Some have even fueled myths that perpetuate the belief that this giant shark lived during the same time as dinosaurs (though they went extinct some 45 million years before megalodon existed) or humans (though we've only been around for about 100,000 years). Based on this reconstruction and additional research, experts believe that this ancient shark had a broad, domed head with a short snout and massive jaws. If the latest reconstruction is accurate, paleontologists believe megalodon was wider than the great white with larger pectoral fins, and could have grown up to 45 to 60 feet (13.7 to 18.2 meters) in length -- about the size of a Greyhound bus.

By comparison, great white sharks' teeth average around 2 inches (5 centimeters) long. Some researchers say that the discovery of new, unfossilized teeth proves that megalodon lives, but zoologist and cryptozoology expert Ben Speers-Roesch explains that these reports are erroneous and ignore the fact that no truly unfossilized teeth have ever belonged to megalodon.

First megalodon: 20 million years ago. First dinosaurs: 225 million years ago. Age of earth: 4.6 billion years. Many theories float around about the megalodon's habitat and prey. For those who accept megalodon's extinction, one theory puts changes in climate and shifts in the continents as the cause. So I’m cettianly going to check this one out.
