Rick Emmer, in his book "Megalodon: Grey wrote about what he called "one of the man-eating monsters of the South Pacific," which left him "more frightened than I remember for a long time. He described it as being "yellow and green The Sea of Cortez, also known as the Gulf of California, is home to many marine mammals, such as these dolphins. The marine mammals, in turn, tend to attract larger predators like sharks. Fishermen in the area have long reported seeing extremely large sharks.

Locals even refer to a creature known as "Black Demon," said to measure some 60 feet long. Fisherman Eric Mack, in July , reported a boat strike with what could have been the Black Demon, which had a tail that rose five feet out of the water. This unknown species could perhaps be Megalodon. It remains unclear how Carcharodon megalodon went extinct, if it did. The supposed extinction of the huge shark, whose jaw and teeth have been reconstructed at the North Carolina Museum of Natural Sciences, remains a mystery.

Did oceanic cooling and sea level drops do it in? This high bite force verifies megalodon could have easily crunched up large whales. For comparison T-Rex has been calculated to have a maximum bite force around 57, Newtons 13, lbs. To view either bite force article, scroll to the bottom of the page to the references section for links. These images show a closeup of the tooth rows of a reconstructed megalodon shark from the Calvert Marine Museum.

Like all sharks, the teeth are continually replaced by newer teeth waiting in rows behind the front teeth. The sheer size of the jaw and teeth indicate a massive bite force. The Megalodon shark is extinct. It is not living in the deep oceans, nor did it evolve into something else. Living Megalodon sharks lie in the realm of pseudo-documentaries and pseudo-science. There is absolutely no credible evidence that megalodon exists today.

For further information on why not to beleive the pseudo-science, go to the "Is Megalodon Alive Article" A 4. We know Megalodon sharks died out at the end of the Pliocene around 2. At the end of the Pliocene, there is a little known mass extinction event. This extinction event usually gets eclipsed by the more famous extincitons, but it was a mass extinction non-the-less. The end Pliocene mass extinction was marine in nature.

It also hit large marine mammals particularly hard. This includes the extinction of Dugongs in the Western Atlantic, and a sharp drop in whale diversity. Whale diversity today is but a shadow of what it once was. Lets look into the details of this mass extinction to see why Megalodon was amung one of the victims.

Many genera and species became extinct. Unfortunately, Megalodon sharks ate whales. If the Megalodons food source severely declined, it would be expected that the Megalodon populations would also dramatically decline. This is a mother and newborn calf at a breeding ground in Vava'u, Tonga. These Humpbacks will migrate to Antarctic waters during the summer months to feed.

The end of the Pliocene was a time of extreme environmental change. Two big changes were the closing of the Isthmus of Panama and the overall cooling of the Earth. The closing of the Isthmus of Panama effectively separated the Atlantic and Pacific Oceans along the equator. This disrupted and changed ocean currents and saltanity levels, which in turn disrupted nutrient flow in the oceans.

Coupled with this is the cooling of the Earth, leading to glaciation in the Northern hemisphere and a drop in sea levels. This again disrupted the nutrient flow in the oceans. These major disruptions of the oceans caused many behavior and evolutionary changes in the surviving whales. Around this time, baleen whales began to globally migrate in search of food plankton. They began migrating into arctic regions as they continue to do today.

Unfortunately, Megalodon sharks were warm water sharks and could not go into the cold arctic waters. As a result, their remaining food source, the large baleen whales, would be unavailable for long periods of time. Without this food, Megalodons would starve. The drastic climate and ocean current swings that would lead to the extinction of many animals also forced the evolution of new ones.

On land, we see the evolution of the Polar Bear, and in the oceans we see the rise of the Killer Whales. Orcas, or Killer Whales are large marine mammals that are intelligent and hunt in packs. They quickly became the top predator of the Oceans. Unfortunately, if there are two apex predators vying for the same food supply, one is going to lose, and we all know Killer Whales did not go extinct. Today, pods of Killer Whales are occasionally observed atacking and feeding on large Great Whites and other Whale species. In the past, it would be no different. Juvenile Megalodons would be no match for a pod of Killer Whales.

Paleontologists knew the megalodon became extinct near the end of the Pliocene Epoch, which was around 2. A research team has recently done a quantitative analysis of the fossils to verify this date.

In , Catalina Pimiento and Christopher Clements analyzed the ages of megalodon fossils from literature and scientific collections. They then used a mathematical technique called Optimal Linear Estimation to infer the extinction date.

    Yet in the late Pliocene around 2. It appears the Megalodon was simply too specialized and could not adapt fast enough to the chaotic environment of the late Pliocene. Millions of years of evolution had made the megatooth shark too large and too specialized to adapt to its changing environment. The fators listed above, and a few other factors, contributed to the extinction of this great beast. There was a day, 2.

If you are looking for a real megalodon documentary to watch, this is it. They come in a bunch of colors, styles, and sizes. There are enough designs for even the most discerning megalodon fanatic!

    Megalodons are made of cartilage. Cartilage is much softer than bone. Because of this, most of the megalodon will not fossilize. On rare occasions, vertebra and fragments of cartilage will fossilize. However, since shark teeth are made of dentin, a very hard substance, megalodon teeth readily fossilize, and are common as fossils in many fossil bearing Miocene and Pliocene formations worldwide. Below are some notable locations where megalodon teeth are found. Two famous global places for megalodon teeth are: They are found on land in the desert regions, with many other shark and whale fossils.

    The export of Chilean megalodon teeth has been banned since The worlds largest measured megalodon has come from the Pisco formation. Megalodon teeth have been dredged from the deep slopes of a fringing reef around New Caledonia. These teeth have eroded out of their Miocene formation and are heavily worn. These South Pacific Megalodon teeth can no longer be dredged.

    However, this location is mentioned here, because these New Caledonian teeth continue to stir up controversy from time to time. Manganese dioxide dating of the teeth in the late 50's indicated an age of 11, to 24, years. However, this type of manganese dioxide dating is now considered obsolete and invalid.

    The teeth from this area are clearly Miocene in age. These New Caledonian teeth are now highly sought after, and many have beautiful scrimshaw artworks on them. The Author Blackwater diving in the cooper river for megalodon shark teeth. South Carolina has a few formations that contain Megalodon teeth. The main formation is the Hawthorne Formation. A while back, one could surface hunt in areas being developed that exposed this formation. The big development boom is now over, and it is now difficult to find places to legally access.

    However, the famous Black water rivers in South Carolina, such as the Cooper River, continually wash out megalodon teeth from this formation. But they may not have known they were holding the teeth of the largest shark ever to call the ocean home. Scientists say the teeth, some of which are bigger than an adult hand, belonged to megalodon, a prehistoric shark species that grew to nearly 60 feet in length -- three times the size of a great white.

    Beachgoers in North Carolina are finding teeth belonging to a foot prehistoric shark https: Offshore storms churned coastal waters last week, and locals think the turbulence may have brought the teeth up from the ocean floor. Wherever they came from, it's been quite a journey. The teeth are at least 2. For 14 million years, megalodon continued to grow in size, becoming the most fearsome predator in the sea.
