Purussaurus brasiliensis (float of 4)  upload.wikimedia.org/wikipedia/commons/7/76/Purussaurus_BW.jpg Order: Crocodyliformes Family: Alligatoridae Length: 10.3 meters Mass: 6.2 tonnes Age and Location: Miocene epoch, 13.8 to 11.8 million years ago, Colombia Killing apparatus: Crushing jaws Was one of the largest species of crocodilian. Had a very strong bite proportionately.

Its fossilized teeth are very popular among collectors. sharkboy101 , here you go! |

Thanks, Dinosauria101
This is an interesting match up, judging by the size of the caimans, the shark takes this in deep water.

sharkboy101That was a typo - I meant 10.3 meters and 6.2 tonnes. It is now fixed. Do you still favor the megalodon?

Dinosauria101, yes
The shark still has the weight advantage.

While I do agree the Megalodon wins, the caimans actually have a combined weight advantage - 24.8 vs 23 tons.
Nonetheless, still about parity, and Megalodon has the power to oneshot each caiman quickly

Are caimans good at coorporating in groups? If not the megalodon wins easily.

Megalodon would win this one, even if the combined weight of the Purussaurus is slightly more, it's not gonna be enough when the giant shark is likely a more maneuverable animal in the water compared to a float of giant caimans. Plus having a stronger bite force.

Not helpless, but not as good. @6f5efd, I kinda agree. I'd favor the megalodon here about 60/40; large opponents often, but not always beat a similar sized group of small ones more often than not |

Just a quick thought. Even with animals that don't coordinate or engage in teamwork, numerical advantage cannot be underestimated. You cannot just look at weight and think, the single animal is heavier so it still wins. It's one animal's durability and ability to inflict damage against 4 animals, all of which can maneuver in different directions and attack at different angles. Just as importantly, it's one animal's struggle to not get exhausted against 4 animals, who - knowingly or unknowingly - can piggyback off the endurance of their partners. This is one reason why orcas are so dangerous, not only are they incredible at teamwork, they take turns and stay fresh while their prey (granted their prey is usually not dangerous other than sometimes its size) flounders, loses blood and just generally becomes completely fatigued.
4 Purussaurus, if they could attack in some type of coordination might be able to tire and hurt the shark (it's a male Meg, so huge but not of monstrous size like some females), even if they also had a great chance of getting hurt. I'm not saying the shark would lose, but it would be a very risky encounter for both sides.

Well, you do have a point elosha. Unless the number advantage is significant, and they're of similar formidability, I tend to slightly favor one large opponent over multiple small ones due to it being durable enough to survive relatively more damage and to quickly kill a smaller foe.
Having said that, that's on land. In the water, where all dimensions are possible, the numbers have more chance.
Crocodilians are also dencently good at coordination. Leaning a bit more towards the caimans now but by no means a mismatch.

At around 23 tonnes mark, the Megalodon (male) is far larger than the individual Purussaurus. The shark will one-shot a member of the float and spook remaining members - to give up.
Crocodilians have sufficient intelligence to employ cooperative hunting techniques but they are not known to take on animals far larger than themselves and prevail.
Crocodilian jaw structure is suitable for grabbing, and the animal is able tear chunks of flesh via death rolls - this will not do in this contest.
A crocodile bit the trunk of an adult elephant but had to give up because this was more than the crocodile could chew through. The elephant put its size and strength to good use to dissuade the crocodile and free itself.

LifeIt's kinda a myth that crocs are not good at taking on larger animals than themselves. They most certainly can, however they are better at bone crushing as opposed to tissue damage due to duller teeth and high bite force, which is what makes a deathroll needed on large and fleshy animals. Having said that, Purussaurus appears to have serrations and very sharp points on its teeth; in addition to a very high bite force - Tyrannosaurus tier. Not to mention they can attack from all directions. The serrations was mentioned in a study; I'll see if I can find it.

Can you show me an account of a crocodile successfully taking on something substantially bigger than itself?

This crocodile was able to take on a buffalo around 4x its weight: www.dailystar.co.uk/news/world-news/780628/Crocodile-attack-buffalo-without-leg-graphic-videoAnd this croc seems to have been successfully able to kill a buffalo 2-3 times bigger: www.youtube.com/watch?v=y_8SGsI2r6gLooks to me as though crocodiles are plenty capable of macrophagy. Probably doesn't happen often, however because of 2 reasons: -Like every predator, they prefer smaller prey -Crocs only need to eat 30-40 times per year - not many of those will be large prey. Add to that the fact that Purussaurus appears to have serrated teeth which is better at macrophagy than crushing jaws. By the way, who do you back here? |

Also, this one: www.academia.edu/35584021/Crocodile_human_conflict_in_National_Chambal_Sanctuary_IndiaPage 107. The crocs seem to have been able to kill several buffaloes ~4 times their weight. Not to mention this (the buffalo would probably have been 2-2.5 times the mass of the croc):  And if that wasn't enough, there's also that 4.2 meter croc killing the giraffe bull (which would be about 3.5x its weight) Crocs seem very capable of macropredation. But they don't seem to do it all that much. |
