The world's largest shark jaw — you can buy it
A shark the size of a semi truck swims through the ocean. Sensing prey ahead, the monster attacks, opening a mouth bigger than a subway car turned sideways, and lined with teeth the size of a man's hand.
Fiction? Hardly. Ancient history? Absolutely.
And next month, anyone with a spare half-million dollars or so can make a play for the most spectacular remains of these prehistoric creatures ever discovered.
The world's largest shark jaw , 9 feet tall and 11 feet across, goes up for sale on June 21, at Heritage Auctions in Dallas, Texas.
The jaws are constructed with 182 fossilized teeth of the world's largest shark, Carcharocles megalodon , which went extinct about 2 million years ago. They represent the life work of Vito Bertucci, a jeweler-turned-fossil hunter who spent nearly two decades searching for the massive teeth used in the jaw.
Minimum bid is $625,000, but the jaws are expected to fetch up to $700,000, according to David Herskowitz, director of Heritage's natural history department.
The jaw has four shark's teeth that are more than 7 inches long — an extreme rarity. "I think there are probably less than 10 known in existence," Herskowitz said.
Mysterious monster The sharks went extinct at a time when glaciers covered large swaths of the globe, "and some people think that may be related to the extinction of this species, but it hasn't been established," said Catalina Pimiento, a Megalodon researcher with the University of Florida and the Smithsonian Tropical Research Institute. Like sharks alive today, the prehistoric Megalodon's skeleton was made of cartilage, not bone, so the creatures left little behind for researchers to study. "The only remains you can find in the fossil record are the teeth, because they're hard enough to preserve through geologic time," Pimiento said. Although that may not seem like much to go on, scientists have been able to use equations based on their knowledge of great white shark physiology — the modern-day species that most closely resembles Megalodon — to extrapolate just how big the ancient sharks grew. The jaw up for sale in June would represent a truly monstrous shark. One that, according to Heritage Auctions, would have been 60 feet long — a large specimen, even for outsize Megalodons. Shark dreams Vito Bertucci set the fossilized teeth in their massive fiberglass frame more than 15 years ago. With the help of researchers, Bertucci based the dimensions and details of the jaw on great white sharks.

Great White Shark: The Reality Of Its Jaws
Great White Sharks are the stuff of nightmares. Tooth upon tooth of razor-sharp rows of teeth, each designed to rip huge chunks of flesh from its prey. One of the most terrifying sights is that of the silhouette of a White Shark’s tail fin piercing the water’s skin as it silently stalks one of us.
Fortunately for us, this terrifying image is mythical, the result of careful Hollywood manipulation. The real Great White poses little or no threat to humans. Attacks are very rare and fatalities even rarer.
Mass Tooth ProductionAlthough many animals can replace broken teeth, few do so in the manner of a shark. Shark’s teeth are grown in rows. Each row is at a different stage of growth. The row at the back are at the smallest and earliest stage of development while the row at the very front are the functional teeth.
Very slowly, like a conveyor belt, each row moves forward towards the front. So the front teeth are being constantly replaced with new rows of teeth.
Weak Bite
Shark bites are much weaker than many people imagine. In comparison to a crocodile’s bite, a great white shark’s is roughly five times weaker.
Great White sharks very rarely attack humans. When they do attack people, the vast majority survive. This is because a shark’s first bite is usually exploratory. It will taste the victim to see if it is suitable as food or not.
Generally, these exploratory bites are very weak 10 kilos (20 lbs). Its proper bite usually exerts 40 to 50 kilogrammes (100 lbs) of force.
Flying JawsDespite sharks having incredibly powerful muscles, their upper jaw is not attached to the skull. This accounts for their bites being relatively underpowered considering their huge size.
But, far from being disadvantageous, having an upper jaw that is not attached to the skull means the shark can fling its jaws forward. This allows the Great White to take a much larger bite out of its prey. All sharks can do this but the Goblin Shark has taken this ability to the extreme.
A Supreme Animal Unjustly Hunted
Great White Sharks are supreme animals. With their jaws and teeth incredibly advanced after millions of years of evolution, they still are the top predator in our oceans.
However, despite all we now know about the Great White Shark, myths still remain and they are still persecuted. Perhaps why we still choose to hunt this endangered animal has nothing to do with rationality and everything to do with fear. A fear that reveals that we are not as dominant as we would like to think we are.
