oh that's pretty big

Fake

>>5118738
but can it beat megalodon

>>5118741
they're both about the same length at their biggest predicted sizes, so that depends if you think a 20m octopus can beat a 20m shark, considering that more than half the length is tentacles

>>5118742
Tentacles become less efficient at applying force the bigger they are. Giant squids which measure 12 m according to these graph >>5118738 eat normal sized fish like orange roughy and smaller squids. Giant squids are also preyed on by greenland sharks which are 6-7m long.
People overestimate how cool/scary cephalopods are. They are just blobs of water tentacles that feed on way smaller prey than them.

in the paper they actually say that the pattern of wear on the beaks is consistent with crushing bones of large prey, rather than crushing shellfish or eating small fish like modern cephalopods. The authors' hypothesis is that they were top predators

That's pretty sick.

>>5118770
yeah the size is incredible
A and B are from cretaceous octopuses, C is from a giant squid

>>5118766
Damn, would it be possible for them to be scavengers? Squids and Octopus nowadays are mostly ambush predators. I can't see how such a big squid can ambush big bony fish/reptiles.

>>5118702
>another made up animal found by le science
You guys do realize we still don't what dinos really looked like right? These are all just theories based on no real facts or evidence

>>5118776
Maybe, but the curse of the soft bodied cephalopods is we won't ever know what they looked like, maybe they were more streamlined

>>5118766
How do you differentiate between bite wear caused by bones vs thick shelled molluscs.

I'm fully prepared for some other discovery in the future to downsize the shit outta the new IRL lusca. See what happened to pic related.
Haggarti's gonna be downsized to Jeletzkyi's proportions by next week, just you watch.

>>5118815
Probably not that much. Haggarti's fossil is much larger than Jeletzkyi's fossil.>>5118770

I read the thing, I find that they're drawing altogether too many paleo-ecological conclusions from a few fragmented tooth fossils.

>>5118815
Why is he directly under its anus and genitals?

Squids and octopuses can't really fossilize.

The mere suggestion that there could have been giant squids and giant octopuses in the primeval past really pissed academics off for no real reason, for some reason.

"There may have been krakens"
"Um non retard show me your evidence"
"I can't; that's precisely the point; they leave very little evidence"

Christ.

it's some interesting stuff
>Frequent durophagous predation on hard-shelled prey causes wear of their jaw tips and jaw edges, which is absent in nondurophagous cephalopods such as squids
>This wear provides reliable evidence of durophagy, in a broader sense carnivory, in fossil cephalopods. The wear was found on adult jaws of Late Cretaceous Cirrata, but not on their juvenile jaws. It is also absent in co-occurring fossil squid jaws, including both juveniles and adults
>In the largest specimens of N. jeletzkyi and N. haggarti, the loss of jaw material caused by the accumulated wear reaches ~10% of the total jaw length, which is more severe than in modern durophagous cephalopods
>These wear patterns suggest that Late Cretaceous giant Cirrata were active carnivores that frequently crushed hard shells and bones. The long scratches distributed on wide areas of their jaw reflect the dynamic use of the entire jaw for dismantling prey. Asymmetric loss of the jaw edges suggests lateralized behavior, which has been linked to a highly developed brain and cognition
>This, in turn, suggests that the earliest octopuses already possessed advanced intelligence. Laterality is known in modern octopuses, whose high intelligence matches that of vertebrates
so essentially the heavy wear on cephalopod beaks imply eating shellfish rather than fish. But in this case, there's extreme wear, up to 10% of the beak which is significantly more wear than modern shellfish eating cephalopods have. The fact that there are long scratches on the wide areas of the beak indicate the use of the beak to rip apart large animals, rather than just crushing shells. And the fact that bones are much thicker and tougher than shellfish shells explains why the beaks are proportionally worn down much more than modern shellfish eating cephalopods.

....Wasn't this already known? We found graveyards of bones in enormous artistic arrangements, typical of the prey that octopuses leave behind...

The idea isn't far fetched. Academics are just not imaginative enough to entertain something very plausible.

>>5118888
Retarded nerds need hard evidence even for the most obvious of shit.

>>5118888
quad 8s confirm

>>5118884
>>5118888
Yeah it's pretty pathetic how people will act like there weren't truly enormous jellyfish zapping the shit out of whales in ancient times
Shit was far bigger back then and we know just how huge some squishy boneless things can get even today still

>>5118888

Those are from the Triassic, not the Cretaceous

>>5118888
There is no confirmation that cephalopods arrange their prey's remains.
They create trash dumps called middens and make sure the remains(usually shells, beaks, and other things without bones typically have, which is what they typically eat) go into them and stay there. But no artwork or anything.

Pretty extreme range of estimates there. I’ll go with around 11m max.

I think the tuna comparisons are more humiliating for dunked-on-osteus

this is the same made up bullshit like megalodon because le jaw big. We KNOW just based on giant squids cephalopods that size can't move too fast without giving themselves strokes. Really expect us to believe a giant octopus was hunting much faster predators?

>>5119004
maybe it was an ambush predator
