1. The MegalodonÂ is consideredÂ to beÂ the most highly effective predator in vertebrate historical past and a better hunter than the great white shark. The most important predators recognized to solely dwell in the deep sea surroundings without touring to shallower waters are species comparable to big and colossal squid, which are in a position to endure the constant extreme pressures of the deep sea because they’re invertebrates.
So as enjoyable as it is to speculate that Megalodon Sharks still exist, they have been extinct for a protracted, very long time. As you all know by now, Discovery Channel ruined Shark Week endlessly by airing a pretend documentary about fake Megalodon sightings by pretend people.
Till proof of an animal, like the coelacanth (which was known only from the fossil record), actually appears, science is justified in concluding from the fossil file that a species is extinct. “A great white is in regards to the measurement of the clasper, or penis, of a male megalodon,” Peter Klimley , a shark expert at the University of California at Davis, stated in a 2008 interview.
Conservationist, shark professional, and Shark Week critic David Shiffman wrote in 2014 that if megalodon have been alive right this moment, it might in all probability be hunted to extinction for its fins. Reconstructions using jaws and different fossilized remains counsel that megalodons most likely reached maximum lengths of up to fifty four feet (16.5 meters), round three occasions bigger than nice whites (C. carcharias).
THIS TIME, I decided to make a joke rebuke of an animal dimension theory that’s actually GOOD, and able to face up to fundamental replication without embarrassingly collapsing in on itself (like virtually each different size-scaling idea on Megalodon).
Within the 1600s, Nicholas Steno, a physician, published a e-book stating that the mysterious “tongue stones,” so-called due to their shape, which had been discovered within the crumbling cliffs of the island of Malta for a lot of centuries, were really analogous to the enamel of contemporary-day sharks.
The Authorities calls in a gaggle of, you guessed it, eccentric scientists who’ve developed a system of speaking to dolphins and orcas, with the thought that they might discover out what is going on on (at this stage the authorities don’t consider it is a big shark, but of course the eccentric scientist already has it labored out).
Although it nearly certainly went extinct virtually 2 million years ago â€” no matter what the Discovery Channel says â€” we proceed to be taught extra about megalodon on a regular basis. There have been also the sharks in the genus Otodus, believed to have been 30 to 40 ft (9.1 to 12.2 meters) lengthy.
Though they appear to be bigger variations of Nice White Shark tooth, paleontologists level to slight variations in the Megalodon tooth and its ancestors as proof that the Megalodon shark will not be closely related to the Nice White.

In some artists’ impressions, the gigantic fish has taken on the appearance of an oversized nice white, with jet plane like pectoral fins, but some palaeontologists consider this to be an incorrect representation, and liken the creature to that of a sand tiger shark.
At more than 60 feet long, megalodon â€” (actually “massive tooth”) â€” was the highest predator within the ocean up till they went extinct two million years in the past. Although we think of the Megalodon as a giant Great White Shark, many researchers believe it might not have resembled one in any respect.
Oh, we cant even find more than a tooth and a saucer sized vertebrae however swiftly scientists are specialists on the Megalodons hunting methods? Not like its cousin the good white, megalodon may have been unable to evolve endothermy, or the power to maintain an elevated body temperature, scientists say.
Many macro-predatory sharks also averted areas inhabited by Megalodon. Elsewhere: Megalodon fossils have been found on every continent besides Antarctica, making them what known as a cosmopolitan species. 5. Snap the artificial Megalodon jaw at 4 occasions the acceleration of a contemporary nice white shark.
Talking of: The museum has a life-dimension reconstruction of the massive jaws of Megalodon, displaying its spectacular 6-foot gape and featuring real fossil teeth. Measure a sequence of arms-on Megalodon enamel to predict the scale of each shark. Marvin the megalodon was a large prehistoric shark.
On land, we see the evolution of the Polar Bear, and within the oceans we see the rise of the Killer Whales. Displaying the change in Otodontid tooth sizes all through time. The MegalodonÂ was greater than a school bus,Â growing as much as 50 toes lengthy and weighing 30 instances greater than an ideal white shark.
As a result of sharks are continuously shedding their toothâ€”thousands and thousands of discarded choppers over the course of a lifetimeâ€”and since Megalodon had a global distribution (see next slide), Megalodon enamel have been found everywhere in the world, from antiquity to fashionable times.
