No, there isn't just one megalodon; the species Otodus megalodon is extinct, dying out around 3.5 to 2.6 million years ago, despite modern rumors and fictional portrayals suggesting otherwise. Scientists are confident in its extinction due to the lack of recent fossils (especially teeth, which are common) and the absence of evidence like large bite marks on modern whales, concluding it couldn't survive in today's oceans.
All the evidence we have leads us to conclude that megalodon is, in fact, extinct. But just because they aren't swimming about in our oceans anymore, doesn't make them any less fascinating. Scientists are constantly striving to better understand prehistoric sharks and revaluate what we think we already know.
For Megalodon to have existed 2.6 million years since the last known fossil tooth, there would need to be a sustainable population. Based on its size (you can see how this is done on my Kaiju post) we would expect global numbers, if we assume the largest Megalodon females get is 65.5 tons, of near ~700,000-1.5 million.
We know that megalodon had become extinct by the end of the Pliocene, 2.6 million years ago, when the planet entered a phase of global cooling. Precisely when the last megalodon died is not known, but new evidence from the USA suggests that it was at least 3.6 million years ago.
It is possible that different populations of megalodon around the globe had different body sizes and behaviors due to different ecological pressures. Megalodon is thought to have been the largest macropredatory shark that ever lived.
Mature megalodons likely did not have any predators, but newly birthed and juvenile individuals may have been vulnerable to other large predatory sharks, such as great hammerhead sharks (Sphyrna mokarran), whose ranges and nurseries are thought to have overlapped with those of megalodon from the end of the Miocene and ...
At a length of more than 50 feet (15 metres) and a mass of nearly 50 tons (tonnes), Megalodon was both larger and heavier than Tyrannosaurus rex.
The Great White Shark is considered the deadliest shark due to having the most recorded unprovoked attacks and fatalities, followed closely by the Tiger Shark and Bull Shark, which are also responsible for numerous attacks in coastal areas. Great Whites are apex predators known for their powerful bites and curiosity, often mistaking humans for prey like seals.
The last megalodon likely died due to a combination of factors around 3.6 to 2.6 million years ago, primarily climate change, leading to a loss of its primary food source (baleen whales) and increased competition from emerging predators like great white sharks and orcas, forcing it out of its preferred warm waters. The cooling climate caused prey to shift to colder poles, while sea level drops reduced vital nursery areas, making survival unsustainable for the giant shark.
The megalodon went extinct 3.6 million years ago, and is thought to be the largest shark that ever swam the Earth.
No complete Megalodon has ever been discovered. This means that important details in reconstructions of Megalodon – body shape, length, size, and weight – can only be estimated and are subject to change with new investigation.
The answer to the megalodon question is a resounding NO. Megalodon went extinct around 3.5 million years ago.
Well, since Megalodon can only swim, in order for them to fight a TRex, the TRex would need to go out of it's element and go in the water. The Megalodon would easily win.
Looking at how science currently stands, we can confidently say no, this is highly unlikely. First of all, a huge amount of DNA is missing, which in addition deteriorate over time. Considering the Megalodon breathed its last millions of years ago, it seems unlikely that good DNA could ever be found again.
1. Whale Shark (Rhincodon typus) 55.7 feet / 17 m. The largest fish in the world, the whale shark, is an endangered species found in most of the world's tropical waters. Like the megamouth sharks and the basking shark, whale sharks are filter feeders and their diet consists almost exclusively of plankton.
Researchers are thrilled to announce the shocking discovery of a living Megalodon—a massive, elusive deep-sea shark once thought to be extinct. The species was found by fishermen local to Funaya Ine, a fishing village on the Japanese coast.
Myth: The giant prehistoric shark Megalodon is still alive today, hiding in the depths of the ocean. Fact: Megalodon went extinct around 3.6 million years ago. There is no scientific evidence that this massive shark still exists.
The fact modern orcas hadn't even evolved yet when megalodon went extinct and that ancestral orcas were bottlenose dolphin-sized small-prey specialist that were physically incapable of competing with even a newborn megalodon is something mammal/orca fanboys tend to ignore entirely.
Enter megalodon Otodus megalodon, the largest carnivorous shark to have ever existed. This scene is the stuff of nightmares, but the reality is that it will never happen. This gigantic shark with fearsome jaws certainly was real, but it went extinct long before humans walked the earth.
What are the most Friendliest Sharks in the Ocean
No, 25-foot great white sharks are likely impossible; the largest reliably measured great whites are around 20 feet (6 meters), with females generally growing larger than males, though reports and estimates sometimes suggest slightly larger sizes, but scientific consensus points to 20 feet as the realistic maximum for modern sharks, making the Jaws shark a fictional exaggeration. While some historical records mention larger, unverified sharks and whale carcasses suggest big ones exist, the growth of great whites generally plateaus, preventing them from reaching 25 feet, according to Savannah Morning News, The Daily Jaws, and Science.
#1 Most Scary Shark: Megalodon
Megalodon was the king of all sharks, a giant that could swallow a great white in one bite. At more than 50 feet long, it ruled the seas millions of years ago. It's extinct today, but the thought of a megalodon lurking in the deep is enough to give even the bravest diver nightmares.
Tyrannosaurus Rex, the King of Predators
Its imposing size, immense strength, and hunting prowess dominated the ecosystems of the Cretaceous Period like no other predator.
“The length of 24.3 meters is currently the largest possible reasonable estimate for O. megalodon that can be justified based on science and the present fossil record,” said Shimada, who belongs to DePaul University's Department of Environmental Science and Studies and Department of Biological Sciences.
