The jaw set is composed of 182 fossil teeth, some over seven inches long and is expected to sell for $700,000 (£436,000) at a sale by Heritage Auctions in Dallas, Texas, on 12 June. Megalodon ruled the temperate and warm waters of all the oceans between 25million and 1.5million years ago.
I've found them in every state along the East coast of the US from NJ to Florida. In NJ, creeks are the most productive areas. In Maryland, the Calvert Cliffs area has some great fossils to find beachcombing. In Virginia and North Carolina, rivers, creeks and phosphate mines produce Megalodon teeth.
Shimada's study, which focused on clarifying the size of the megalodon, says the “tallest known tooth†is 6.4 inches and it's on display in the Evolving Planet exhibition at Chicago's Field Museum of Natural History.

megalodon dentition consists of a whopping 276 teeth! This is calculated as 46 front row teeth (24 upper and 22 lower) and the file comprising 6 files (rows behind the front row).
High quality teeth of this size run between $250 and $500 or more. For large teeth (6 inch) expect to pay over $300 if they are beat up looking and $800 to many thousands and more for a high quality 6 inch tooth.
This data suggests that mature adult megalodons had a mean length of 10.2 metres (about 33.5 feet), the largest specimens measuring 17.9 metres (58.7 feet) long. Some scientists, however, contend that the largest forms may have measured up to 25 metres (82 feet) long.
They assume that all teeth are the same, and as such, they are all worth the same amount of money. The fact is that shark teeth come in a wide variety of types and vary in value from less than $1 to well over $1,000.

When it comes to size, the blue whale dwarfs even the largest megalodon estimates. That's more than twice the size of even the largest megalodon size estimates. Blue whales and other gigantic whale species have evolved to be so largely because there's no apex predator the size of megalodon in today's ocean.
Scientists from Zurich University have proposed the largest shark that ever lived became extinct due to a lack of prey and increased competition from predators. Carcharocles megalodon lived between 2.6m and 28m years ago and could grow to up to 18 metres in length.
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.
According to research, even the newborn baby megalodons were fairly large, measuring 6 – 11 ft. long at birth. In terms of longevity, the estimated lifespan of the megalodon is around 20 – 40 years. However, a healthy and fit megalodon may live even longer.
According to website Exemplore: “While it may be true that Megalodon lives in the upper part of the water column over the Mariana Trench, it probably has no reason to hide in its depths. However, scientists have dismissed this idea and state that it is extremely unlikely that the megalodon still lives.
