Megalodon renowned for being the most massive, most powerful predator shark of vertebrate prehistory, the Megalodon Carcharodon had a profound impact on the marine Miocene environment. Evident in the extraordinary discoveries of modern times. From the Miocene to the Pliocene epoch's (the Neogene period) Megalodon's preyed on ancient, miniature whales named Piscobalaena nana as well as large seals.
The question of why such a proficient and mighty hunter should have become extinct was recently readdressed, and a new piece of the puzzle authorised through new finds in fossil bones. The miniature whale P. nana lived in warm coastal waters, they became extinct around the same time as Megalodon, in fact around 400,000 years after the whale's extinction Megalodon left the fossil record. At about that time, some three million years ago, a glacial freeze caused water temperatures and sea levels to drop, it's theorised these factors caused the miniature whale to become extinct.
In their place, more massive whales better adapted to colder waters came to dominate the marine scene, and Megalodon perhaps struggled to compete with the larger cetaceans and predate them due to their size. Also, the leviathans would migrate to the poles where Megalodon was ill-equipped to deal with much cooler temperatures and could not possibly follow. The research has been taken from the study of bones from the fossil remains of miniature whales and seals, displaying bite marks of the Megalodon teeth, suggesting these marine cetaceans were the shark's primary source of prey and not, as previously thought, the more massive whales.
Megalodon reaching a maximum length of 16 to 18 metres, approximately 52 to 59 ft, the closest living resemblance is the Great White shark, 'Carcharodon carcharias'. However, fossil Megalodon remains suggest that its build was much stockier than that of the modern-day Gt. White sharks.
The sharks greatest weapon were 250 teeth, set in rows in the large jaws which continually rolled forward and were lost as the animal bit into prey, so it's no surprise to see many of them discovered in the fossil deposits of North America. However, finding teeth of rare size and desirable quality proves more problematic. Fossil hunter-divers are having to search further and longer, which brings more challenges, longer dives with specialist equipment, fraught with many other professional and health and safety issues and more expense. It is no surprise that the price of good teeth keeps ahead of inflation. Our selection is of high quality, with outstanding enamel preservation have been discovered mainly in the Beaufort county of South Carolina, USA and other locations, dating back to the Miocene epoch.
An Important 'blue' Beaufort County, Megalodon shark tooth measuring just under six inches (the size is delineated from the greatest archetypical lineal length measurement from the root to the crown tip), discovered in South Carolina's. The tooth displays delicate serrations; these provide an insight into the age of this particular tooth, fine serrations, the more advanced the era from which the Megalodon evolved. This Megalodon tooth demonstrates a standard of preservation and condition which is in the top fifteen per cent of the best-preserved fossil Megalodon's in the world today.
