Meet Dunkleosteus, perhaps the fiercest fish that ever existed. It lived 360 million years ago and was twice as long and three times as heavy as a great white shark. From the Show: Top Ten Deadliest Beasts bit.ly/2q92EHb
DUNKY! That specimen has always been a highlight of my visits to the Cleveland museum of natural history. The whole area of the Midwestern states was once covered in a sea, that these creatures lived in , so the fossils were found in that region.
It sounds like a fitting heavy armor themed name. The heavy emphasis of "dunk" and the meaning of "osteos" fused together to make a really cool sounding name. Otherwise this isn't an animal to be fed with.
That mouth is not designed for suction. It looks more like a snapping turtle or pirahna skull. The mouth of a fish that uses suction is completely different. It has the ability to expand and retract creating pressure. If I had to take a guess, I would guess that those huge teeth were meant for huge crustaceans.
Agreed - the upper jawbones of modern fish are capable of detaching and rotating, allowing the mouth to expand outwards and forwards. Dunkleosteus jaws we're only capable of a basic scissor-like open-and-shut motion (as with all other Devonian fishes).
They’re not actually teeth. It’s just the way it’s jaw is shaped :D idk if it actually had teeth, but the ones we see are actually just the jaws being pointy which make them look like teeth like a snapping turtle :D
The big part of the suction, it seems, was simply because it had a large mouth that moved very fast (their anatomy made it so their mouths could fully open and close in about the time it takes you to blink if I remember correctly, and while maintaining substantial bite force). As for the plates, modern studies seem to point that, given how the plates developed, younger members would hunt primarily soft bodied prey they could slice up with their guillotine-like jaws, such as sharks, while larger adults made full use of the frontal spike like protrusions to hunt large armored prey, such as large mollusks and juvenile dunkles, canibalism apparently being something that wasn't uncommon.
Dunkleosteus was pretty badass. 400M years ago, Mother Nature did not even have time to invent jaws yet. Jaws are needed if you want to chew and eat properly. This thing just sliced and diced its way through life.
It's probably also so that they can easily include scavenged carcasses in one phrase. Scavening is common even among animals which are called "predators'.
Maybe because predators usually have many different kinds of available foods. So its like how an item at the supermarket wouldn't have you as an item since that is a one way description from the predator's perspective.
The tactic of drawing the bait towards the cage to get those shots of the shark really is wrong. The shark is trying to feed then gets drawn into accidentally biting a steel cage.. that's going to potentially hurt the shark. Horrible to do to the animal just to get a shot that appears to be attacking the cage.. stupid and crule!
It's why humans get what they get. Fuck with the Eco system the Eco system rips humans to shreds. U get what u give. We ain't see nothing yet. And government can't, won't help. They'll save selves 1st. See videos how many cops, pigs ran from ground zero.....
It doesnt hurt the shark at all...sharks have no nerves inside their mouth or on their gum in order to eat turtles without being badly hurt by sharp pieces of shell,they also change teeth as much as needed so even if a shark breaks all his teeth on a cage,they will be replaced within 48hrs
very educational and entertaining as well....For me DUNKLEOSTEUS is one of the most fearsome extinct marine creature ever ... thats why i made a custom of it for my CHANNEL... ( its a lego like figure only) .... i want to make more more extinct fish/marine soon... i want them to be featured in my channel ... they deserve an equal footing ... btw cool video keep on coming
They did the math, ran a simulation and speculate the placement of muscle tissue then apply it on a specimen. While it is not the most accurate they certainly know better than you
Theropod Hunter Because there are actually people who genuinely believe that it could kill a shark twice its size. It’s hate for the dunkleosteus fanboys, mot the dunkleosteus.
Joel Mcdonnell As far as I know they look at the bone structure and estimate how much muscle was in certain places like the jaw for example. Also dont forget we are all relatives of even this fish and the fish itself still has close relatives nowadays so they use that as help too. For instance crocodiles are often used to help recreate the muscle structure and bite force of Tyrannosaurs.
Ah, thus the attack of the almost cult-based fandom of the Megalodon and Its perpetrators against another aquatic pre-historic creature and Its newly-found admirers has ensued ! How marvelous !
Absolutely no chance, unfortunately. Devonian mass extinctions were among the nastiest (that wiped it and most likely every armored fish out) then would've had to live & thrive for hundreds of millions of years & survive 3 more very nasty mass extinctions, including the worst one (end Permian). Unheard of for a top predator to survive hundreds of millions of years... Although it doesn't feel like it, we're many magnitudes more likely to find a living breathing plesiosaur than this, odds of which are also extremely slim to next to none of course
Not really teeth, bony mouth plate like things that self sharpen. As to why marine predators after this mostly evolved & had teeth, who knows, (just speculation maybe more resilient creatures in lower tropic levels could survive past mass extinctions better if they had constantly replacing teeth, as majority of marine predators do (& maybe not enough time/ space in the food chain for something like this to emerge again?)) Tho it is somewhat crazy to thing these lived closer to when jaws first evolved in any animal than to the first dinosaurs (or even the first trees maybe, haven't looked it up). Nature was experimenting for sure
Some predatory fish nowadays do it all the time, the suction is very effective to catch smaller things just out of reach Plus they only have to do it once unlike blinking eyes, think of it like a reverse canon that needs time to load but they only need the one shot.
Because Marine Biologists and Paleontologists actually took CT scans of the jaws to make 3D models on their computers, which can be analyzed. Not everything is pure speculation.
They scanned the mechanical energy transfer system of the skull with computer scans via 4-bar linkage mechanism. It's possible to analyze literally every animal with a jaw this way, even if they are extinct.
@@BaronessAishi055 Haha, right. Because these scientists know precisely how everything works, especially things that are several thousand years old! Were they there? Did they conduct studies on a live Dunkle? Speculation!
Pyrozeus The average Great White is only about 13.5 feet long. They’re saying that Dunkleosteus averaged around 25 feet long. So no, Great Whites are definitely not bigger than Dunkleosteus. Although it is true that maybe some of the biggest Great White specimens ever could grow close to 25 feet long. But generally speaking, the species Dunkleosteus was in a whole different league than Great Whites in terms of size.
