Full Version: Does Megalodon Still exist?

There are lots of reports of Megalodon being alive. What do you think could it still be out there?

I've been reading about sharks and collecting fossil teeth since I was a kid and i'd love to discuss the subject.
N-droe
Well, I think it sure is possible that it still exists.

But I got a question. A couple of months ago I read an article about Japanese research. They dropped a container into a ocean trench. This container was filled with food and rigged with a motion activated camera.
In one of the shots made by the camera, they saw a huge shadow of some kind of fish (or whale). As far a I recall the sharks eating the bait in the container al swiftly left the container as soon as the shadow came into the picture.
This shadow was estimated to belong to a 60m long animal.

Can anyone point me to this article again? And to other articles about follow-ups on this research? I like to know what's going on.

These kind of things surely make one believe megalodon is still out there. It's a big ocean and we're very small.
Invisigoth
I think it was a Pacfic Sleeper shark that bumped into the camera

It simply can't exist, or one would have been caught or spotted. A creature of such size could only be hiding from science in the depths of the sea, but there is a problem with this: The Megalodon belongs to the genus Charcharodon, so its closest relative is the Great White, but the Mako and the Porbeagle are also close to it, and none of these are deep-sea species. It is highly improbable, that such a difference could occur in a family of animals(deep-sea living obviously requires different morphology, and that would place the Megalodon in a different family.) Furthermore a large, deep-sea carnivore could not find sufficient amounts of food, because as one goes lower, the animals tend to get smaller in order to be able to bear the pressure and a 16 meter shark could not wait for the occasional appearances of Sperm Whales and such animals, because they do not spend that much time in the great depths.

I tend to agree with what you said though I support the idea that Megalodon should be listed in the genus Carcharocles instead of Charchaodon. I think the line of sharks that evolved into Meg broke off much Earlier . I also think that the White shark evolved from a line of prehistoric Mako sharks and not Megalodon.

Interesting topic. But I sure wouldn't want to swim and see one at the same time! tongue.gif I chose the

i vote yes. ocean is to big to declare it 'extinct' just cuz no one seen it around for so long

as i understand it the genus Carcharocles is the ancestor of the mako.
the evidence is suggesting that the megalodon is the ancestor of the modern day mako,
the great whites ancestor is at the moment undiscovered and was most likely a regular sized shark.

Well, a perfect taxonomical categorisation is quite an impossible task, because the only things that has ever been found in context with the Megalodon are its teeth...

How lucky for us that we commonly identify shark species by the shape of their teeth then

I voted yes. I think that the ocean is too big for us to assume that we've found all living species of sharks.

I agree, the ocean is vast and we know very little about what's all out there. My 8 year old son really love the idea of huge sharks. Megalodon is a big hit in our house. Other than that, I'm lost on the whole shark evolutionary tree, but I am interested to read what you all have posted.

True, but without having a complete jaw, or some sense of the body shape, the Charcharodon/Charcharocles debate can't be settled. Different lamnoid teeth can be really similar...

There have been vertebrae from Megalodon found as well. And as far as the teeth go other than being triangular the teeth are pretty different from each other.

Between the great white and Meg that is.

Of course there is a difference between the two's teeth, because they are different species(the teeth of a grey wolf and a bulldog are quite different although they are in the same genus, namely Canis). And from a single vertebrae(they re extremely rare, because cartilage is not usually fossilized) not much can be found out.

Awesome! Anybody who is intriqued by Megalodon Sharks should email me. We could be good friends! lol! I love Megalodon Sharks. I dream of going to South Carolina and finding some Megalodon Teeth in the sand. Of course I'm sure that will never happen, but damn I'd love to do that. I've bought some off ebay. They are Just AWESOME!!!! I'd die for a white tooth. The bigger, the sharper, the whiter, the more INCREDIBLE they are.

As for my theory if they are still alive. Well I honestly believe they never went extint. I think they lost their teeth as the ice age came along. Mass extinctions took place as new species arrived and become smaller. Sharks are like cockroaches. They are very resiliant to their environment. I think the Megaldons food source become slimmer, therefore they lost their teeth and began becoming more advanced as filter feeders (Whale Sharks) Hey! It's crazy, but not a real bad theory.

And say some science wiz comes along and says" The whale shark has absolutely no ties with Great white/mako shark ancestry." Ok! I'm cool with that.

But some of the Megaldon teeth have been dated 10,000 years old. If that is ture and carbon dating is not wrong on those teeth, then we have an idea that these huge monsters survived the harshest conditions of a 100.000 year ice age. Perhaps they didn't quite make it to the modern age. But then again, what if Carbon Dating isn't accurate at all?

It seems a lot of animals around today are just smaller versions of their ancestors. What if the Megaldon just become a great white and the great white shark didn't really exist prior to the megalodon?

I have no idea, but I'm just saying that the possiblity is there. The sea is HUGE! There are things we don't even know about living in our oceans. I once found a surf board with massive bite marks in it. I was thinking it brushed against some rocks and I'm sure that is all it was, but some times it makes me think. Damn what if that was some surfer who was eaten by a megalodon?


I wish more than anything I could see a megalodon. The size and fear it could instill would be something just truely amazing to see.

i like the way you think thumbsup.gif i cant wait till the movie 'Meg' Comes out next year
XANITHAR
Theres another Megalodon Movie coming out next year?

I'm am so crossing my finger hoping it's decent. I've seen a bunch of Megaldon movies and they....>SUCK!

Poor story lines, poor actors, Well B movies just to say the least! Bad animation.

The teen party boat where everyone gets eaten except for the blonde bimbo and super dumbo macho man retard always survive. Or its the dumb blonde bimbo and super lame scientist who discover the Megaldon and kill it with a bottle of hairspray or a 2 liter of Pepsi Blue. lol!

Oh yeah or the Shark surviving from the Thermal Oceanic vents behind a massive cave of rocks. LOL!

Damn! I'm crossing my fingers hoping this new movie is at least somewhat respectable!

Now you got me curious. I gotta go research this!

Oh yippee, another shark bashing movie. 'But it's OK, these are extinct sharks'. Oh yeah? Think the average Joe is going to know the difference between a megalodon and a Great White?
Undefined_innocence
As i have posted many many times, and i will yet again, The ocean is a VERY BIG PLACE. And things evolve. The Megladon may not be what it once was, but i believe it to be out there somewhere.
Clobhair-cean
There is a wee problem with this "megalodon evolved" theory: If the Megalodon changed, then its not a Megalodon anymore so it is extinct. The Australipithecus is also extinct no matter it evolved into Homo Sapiens.

And if there are living megs, why didn't anyone in the past decades found a single, recent tooth? Sharks tend to loose enormous amounts of teeth during their lifetime, it can be measured in thousand or even hundred thousands...

indeed. If creatures spend all their lives in the deep ocean, any remains of them are likely to sink to the sea bed, where we've only begun to scratch the surface of exploring. So i think it's quite plausible that no remains have been discovered.

But the evolution question is a sticky one; if there are creatures still living that were there in prehistoric times, that does raise a few questions doesn't it? disgust.gif

The ocean is indeed enormous, but that does not prove anything. As far as we know, the Megalodon lived in the upper regions of the sea, like the great white or the tiger sharks, and without serious morphological and other changes, it couldn't have moved a few hundred/thousand meters deep just because it had the mood for it. Also, the Megalodon was supposedly a warm-sea shark, and it is really cold down there.

Take a look at this site, it should explain some basic stuff: Link
Undefined_innocence
Over thousands of years a species can become acoustomed to different types of weather and changes. If not, then we would all be extinct.
In the deep waters of the oceans there are plenty to eat. Plenty enough to satisify the enormous cravings of one as large as the megladon.
And yes, as someone said before, if it has evolved then it is different. BUT ....... BUTTTTTTTTTTTT... It still proves that it didnt die out when scientist seem to think it did.
It proves that a varity of the Megladon still exist. Even if that turns out to be the Great White, then that in itself would be a discovery worth discussion.

There hasn't been a single animal that changed its habitat to a place where there is less food available to eat. Also, evolutionary changes usually leave a trace, for example the remains of the hind limbs are still present at some whale species, and the swimming movement of marine mammals also shows their ancestors, whereas no such clue can be found in modern sharks that points to the Megalodon(and 11.000 years is a bit short for such a huge specialization to take place, furthermore sharks are much less flexible when it comes to enviromental changes, than humans). Plus, not a single piece of evidence is available that would suggest that the Meg is alive: no teeth, no suspicious scars on whales, no eyewitness accounts, absolutely nothing!

theres eye witness accounts, like the time the father and son saw a shark larger then thier boat, and the time the fishermen were out fishing and saw a giant 50-70 foot shark pure white in colour and never went back out to the ocean ever since then

Theres no maybe choice. I voted no but I'm 100% sure, if it was found out tomarrow they exist that would be great.
GoddessWhispers
Well, they have discovered various species of giant squid, that may support the theory architeuthis dux still exists, so I won't say it's impossible for Megaladon to be hiding out there somewhere.user posted image

However, if it did I believe the Oceanic science teams would have noticed something awry. Like whale populations and large kindred shark populations, declining in drastic numbers due to the outbreak of a large appetite and teeth!user posted image
