ok i have No idea what this is, is is as big as i think it is????

it's probelly fake or something i dunno but cool video,

http://www.youtube.com/watch?v=RTKzrVv7I_o&eurl=

It has been posted at least two times before. It is a pacific sleeper shark, not a Megalodon.

Ahh ok, are they really that big???

I placed a translation of this video here in this forum...search for "Possible Megalodon In Mariana Trench"

The shark looks bigger on this film because it is really close to the camera. Plus, the only reference point to the size is a rattail fish that bumps into the shark (rattails are usually shorter than 1m). Still, Pacific Sleepers can grow up to 7 meters, which is quite impressive.

Ah okies it just looks massive cause of the cage in the floor and it looks liek it lies on it lol

Kid, dem words dat ya said mek mi wanna tear dat roof down! One in dem back of da shark!

Stop speaking Dutch, please :D

I have actually heard that scientists found that the megladon may still be alive,though I find this hard to believe.By the way,there are some big sharks out there,ever seen a whale shark?They are huge,but completelt harmless.

Not true.
Megalodon existed 16-1.5 million years ago. No scientist has found that Megalodon may still be alive. Some have speculated that it might have survived to 11,000-24,000 years ago (based on inaccurately dated teeth).

The shark in the video, as I have said a million times before, is an extraordinarily large Pacific Sleeper Shark, a close relative of the Greenland shark/Sleeper shark. Eugene Clark estimated it to be about 7 meter (23 feet) long. Normally they rarely pass 4.5 meter (14 feet). Video was shot in 1990 if I recall correctly. There have been tales of Greenland sharks of about 7 meter as well, frequent mentions of a 7.3 meter (24 feet) specimen are common, but I have found no substantial information about this find, the largest one at least somewhat verifiable was 6.4 m (21 feet) long and weighed 2,250 lbs (1,021 kg). Another specimen weighed 1,400 kg (3,000 lbs) but was not measured.

I know that its not a megladon,im sure you are correct about the species,but I did hear that about the megladon possibly still surviving,but,as I said,I doubt it

Obligatory Godzilla comment.

the only way it can be still alive is if its really really really rare, if it is and scientists say no it cant be its extinct, well i doubt the scientists and ships across the pasific ocean are within every square mile to each other so they can know if its alive or not, so we really cant be 100% sure yet

I believe that in another topic someone said that there was an article in National Geographic about someone finding a megaladon tooth that was only 15-20 years old.

hmm... miniatur cage ?

i know,its not megaladon........
i have seen it s jaw in some site.it was very big.some 7 people were standing behind it....like it is swallowing all those 7 at the same time

Those jaws are not accurately scaled. The actual jaws of Meglodon were only 4 feet high (122 cm), not enough for a man to stand upright inside.



We're not talking a deep-water plankton-feeder here, but a giant shark feeding upon large marine mammals; it's very unlikely such a striking creature would be unnoticied. The Great White shark isn't exactly common.



What? Link? I think you are confusing it with something else.

That is still a very cool video, Megalodon or not. A Pacific Sleeper shark that large has got to be a record in my book. As for real Megalodons still surviving, well, you have to remember, the larger something is, the more it has to eat to survive, that, and sharks don't suffer from compression. What does this mean? It could be that a small number of them do still live, but live in very deep water, perhaps a mile down or more. There is plenty of food there for something that big. I am reminded of all the species that scientists and reserchers have claimed to be extinct are found not to be. Perhaps the Megadon is extinct, then agian, maybe it isn't. We don't know everything after all. Do we?

P.S. In case your wondering how big 23 feet is for a shark, the origonal "Jaws" movieshark was 25 feet long.



Good Journey.



Kyle Rajasthan.

Not only were it's jaws mis-sized, but the entire animal's scale. It's estimated it was probably only as big as a Whale Shark, not the 100 ft monstrousity it was previously thought to be. There is also speculation it was related to(and shaped like) the Tiger Shark instead of the Great White.

I could be wrong about this, but fossil evidence shows the animal was a shallow water predator; it would definitely be noticed if it were still alive today.

Just remember: during the making of Jaws, a dwarf was sent underwater in a small cage to make the average-sized Great White that they had attracted look bigger. And it worked.

Damn. If that's true, it's disappointing.

All I had to say was holy sh**, but still give me the creeps.

Nena is right. No Megs here.



Orca was too much competition for them same as we were too much competition for Neandertal. Too large for their ecological niche, they died out a very long time ago.

From time to time the fishermans tale from Australia sighting one pops up as "evidence". Nope. No megs here and now. Sleeper sharks are protected.

This thread should be extinct, IMO. Sheeeeeeeeesh, how many more times can "they don't exist anymore" be repeated?

grand.

I'm preatty shure that a megladon skellitan skelitian or at least part of one has been found that dated back to only 200-100 years ago.

^'nother wan dat me wanna tear 'nother roof down! Yai!


That part that you meant perhaps was the fossilized tooth, which was actually a mistake in carbon dating. It has been thoroughly discussed in this forum before...

Its a 26 feet pacific sleeper shark i saw it on a tv program.

Actually, yes they have. They found a Megaladon tooth that wasn't that old. Then there have also been some sightings, but not very many. I'd say there are probably a couple still hanging around near the bottom of the ocean.

NO They have not.
This was the dating on the Manganese deposits ON TOP of the fossils. Read back a wee bit.
There has been one "Story" not a single sighting.
No, they are all dead. Plenty of proof has been displayed over and again in this forum. For some reason, people want to believe in these things.
The great white took over the ecological niche these creatures used to dominate.
Closest thing to a sighting around is the rubbish spouted by Steve Alten to attempt to improve his sales.

Oh...so carbon dating is not accurate. Didn't think so. So how do you know dinosaurs are really that old?

Please re-read what psyche101 is saying, where does it say carbon dating is not accurate? I believe he's trying to point out that they dated the wrong material, manganese deposits on top of the tooth to be exact.

Plus, even if the carbon dating was accurate, as close as it could come was within the past 10,000 years. It didn't say the thing died last week, or even last century. However long ago that tooth found its way into the fossil record, the animal that produced it has been dead a very long time.

Besides, based on what we already know from the fossil record, Megalodon were shallow water predators. If they were still around, we'd certainly have plenty of sightings. And no, they could not have shifted habitat to deeper trenches, as there would not be large enough prey to sustain them.

^^We shall overcome...one sensible person at a time

Good lord man, do you read??
Of course Dinosaurs are that old. Have a look at any fossil. For Pete's sake, the things have turned to rock, do you think that happens overnight? The only tools you need here are eyes and a functioning brain.
Here is a page on synthetic diamonds. It might give you a little info on how difficult it is to reproduce what is formed naturally and what processes one must apply.
Now imagine the time scale nature needs to apply such a process to turn bone to rock. Now remember that all these species (527 dinosaur genera have been identified with certainty so far, and 1,844 genera are believed to have existed) are supposed to have lived, died and turned to stone.
You may also find this link relevant - How Fossils are formed. Carbon dating aside. I ask you only look at a natural process and use common sense.

Now to top that off, all fossils have been found in different rock strata, relating to the time period that substance existed. Surely, you can see that rock has needed time periods to form into the layers we see today, I do not see how you could argue that all rock was formed at the same time. There is no evidence at all to back that theory. Not to mention it makes not sense, Heck, get out a picture of Chewbacca if you are going to argue that as a possibility.
And in this thread, we are only talking about the saurian time frame i.e Mesozoic era comprised of the Triassic, Jurrasic and Cretaceous!!!! Consider the Hadean eon If you have a read on that it will blow your creationist socks right off!!
Point is, we have copied nature and know what forces are needed to make rock form, fossils etc. To apply these in your backyard is gonna take an awful lot longer than 6K years, let alone host a plethora of species that have all lived, died and turned to stone. The carbon dating process at least has a documented process. You only need to look at what is around you to confirm this. Use you head man.

In any case, as Moredhel84 said, I was refering to the manganese deposits on top of the fossil teeth. All that has ever been found of the animal are some teeth and a couple vertabrea which have fossilised. Why on earth would you suspect this ocean going behemoth still exists with no evidence? Are you a Steve Alten fan or something?

Hehe, Onyxdk, I do enjoy your style of wit
