We’ve all heard of this mysterious, monumental shark: Otodus megalodon. However having been extinct for thousands and thousands of years, how a lot do we actually learn about these large, historical sharks?
The reply, briefly, just isn’t rather a lot. However we do know a handful of issues, and whereas scientists work to uncover extra details about these mesmerizingly monstrous elasmobranchs, I’m right here to let you know about some fast (but jaw-dropping) info about our legendary buddy, the megalodon.

Megalodon was one of many largest fish the world has ever seen.
This large shark was not solely the most important shark to ever stay, but in addition ranked as one of many greatest fish till the species went extinct. Megalodon was estimated to have grown as much as 60 ft lengthy: that’s round thrice bigger than your common nice white shark! As we speak, the most important fish within the sea are whale sharks. These filter feeders usually common in size between 18 and 32.5 feet. For somewhat added distinction, the utmost size of your common faculty bus measures roughly 45 ft. Yep: that’s a very large shark.
Opposite to widespread media, it seemed a bit totally different than only a big nice white.
Most trendy depictions paint megalodon as trying very like a supersized nice white shark, and far of that is because of the truth that scientists thought for fairly a while that the good white and megalodon shared a standard ancestor. As we speak, it’s believed that megalodon was truly the final species of a separate lineage of shark. When it comes to its look, ways that it differs out of your basic nice white embody a extra compact jaw, longer pectoral fins, and a shorter nostril, referred to as a rostrum.
The phrase “megalodon” truly means “massive tooth”
The ‘massive’ half isn’t any joke both: these enamel grew as much as seven inches lengthy! Given the typical general measurement of those animals and the dimensions of the prey they consumed (massive megafauna like sharks, whales, and so forth.), the dimensions of their enamel is sensible. If you wish to see one thing actually mind-blowing, lookup a photograph of a fantastic white’s tooth (that are already hefty) subsequent to a megalodon’s. Discuss residing as much as its title, proper?
Their fossils have been discovered everywhere in the world.
The earliest of those fossils date again to about 20 million years in the past, and it’s thought to have gone extinct somewhat greater than three ½ million years in the past. That’s an insanely very long time as the most important shark within the sea, huh? You gained’t discover megalodon skeletons as fossils, as a result of like these of recent sharks, they’re fabricated from cartilage as a substitute of bone. However we do have fossilized megalodon enamel, as they’re fabricated from a tough calcified tissue referred to as dentin.
Megalodon enamel are surprisingly widespread: like most sharks. are continually misplaced enamel all through the course of their life. Since megalodon swam freely in tropical and subtropical waters everywhere in the globe, these fossils have been reported to have been discovered on every continent except Antarctica.
Their enamel and vertebrae aren’t all that’s been discovered, although… 💩
That’s proper; scientists have apparently discovered petrified parts of their feces, too! One report from a web site in South Carolina paperwork coprolites (the flamboyant science time period for fossilized poo) of a big shark, the most important of which totaled round 5.5 inches lengthy. I’m truthfully unsure what else to say about that apart from, properly, it’s a definitely attention-grabbing story to inform subsequent time you’re in South Carolina!
Put all these enamel collectively, and you’ve got what’s calculated to be one of the vital highly effective chunk forces on the planet.
With a jaw estimated to measure about 9 x 11 ft, scientists have calculated that megalodon’s chunk pressure can be about 40,000 kilos per sq. inch. Examine that to Tyrannosaurus rex, which had a chunk pressure of 12,000 kilos per sq. inch, and it’s clear you’ve obtained a mighty chunk in your fingers. Nonetheless not satisfied? Our chunk pressure as people averages only a bit greater than 160 kilos per sq. inch. Based on consultants, that 40,000-pound chunk pressure is essentially the most highly effective of any creature that has ever existed.
Although popular culture has definitely sparked rumors through the years, a lot of the consultants don’t assume megalodon continues to be alive right now.
For those who’ve ever seen the movie The Meg, you realize what I’m referring to. There are theories which were unfold by means of the grapevine that, hey, if 80% of our ocean nonetheless stays unexplored … how do we all know for certain that this creature has truly gone extinct? Couldn’t it, maybe, evade human detection within the deep sea? Whereas definitely an intriguing and mind-boggling thought, the overwhelming majority of scientists don’t consider this to be potential, primarily pointing to its measurement as the issue. A lot of the megalodon’s potential prey stay in shallower ocean zones the place there’s plenty of meals to eat reasonably than the deep sea. If these animals have been the truth is alive, scientists say, there’s no approach we wouldn’t have at the least some thought of it.
And there you go: seven wild info about one of many largest fish (and most legendary shark, for my part) to ever stay. Who is aware of … maybe a fossilized megalodon tooth may very well be present in your personal yard!
