A pack hunter that not even Argentinosaurus could handle...

[@ezradanger]

The fact that so many people are so reluctant to consider pack hunting in dinosaurs is weird to me. I'm with you on this one.

[@_coffeebee_]

I figure because most big predators don't hunt in packs in today's time -- except for lions. Also they try and locate bones close together and usually they are more spread out. But I really want dinos to be pack hunters as well, it would be so cool.

[@dunit911]

Mob hunting is more likely in predators of this size from what i understand. Which is just as badass. But I’m sure small family groups hunted in packs. Like two mating rexes taking down a bull trike. Seems likely enough

The other problem with flesh-grazing is that open wounds render the prey highly vulnerable to infection.

[@napalmholocaust9093]

Things like lamprey secrete antibiotics. Even your saliva does.

[@nikitab.6600]

Why would that be a problem? The prey would die and be scavenged.

[@Gabriel-bt7ix]

Eating gradually a living Sauropod cause he is too big to be killed is such a interesting and brutal hypothesis But I think it's more like komodo dragons when they group up only for hunting a large prey like a buffalo

[@dunit911]

Yeah this. I feel like active pack hunting in large animals like mapu is rare even now. What? Lions are the only thing i can think of…tigers and bears are big but territorial. You see bears fighting each other even when food is plentiful because they don’t like to be near each other. Komodo sharks and crocs mob hunt. They kinda just attack large prey items because they happened to be in the same place. Not a tactical pack hunt

[@CreatureLove-A189]

To me it would make sense that the Mapusaurus specialized in taking down Argentinasaurus and other large sauropods. There are prides of lions in the arid parts of Africa that specialize in taking down Elephants and Rhinos. So it honestly makes sense for these gigantosaurids to have a similar specialization to survive in an arid enviranment in Argentina.

Thank you so much, really glad you're enjoying them :) I must say, I'm playing around with a few new series ideas and that sounds like a good one :D

[@AncientWildTV]

the outcome would depend on many factors, including mobility, weaponry, and strategy... but Mapusaurus was a formidable predator and would be capable of taking down large prey!

[@KnightlyNerd]

I quite like Duane Nash’s theory that big carcharodontosaurids were essentially “bonesaw woodpeckers” - that is to say, using back and neck muscles to piston the head backwards and forwards and functionally saw through meat and bone, allowing them to process large carcasses. It’s basically like a shark, which moves side to side when biting, only instead its back and forth.

Really nice video, don't know why you don't have more support haha

[@lifdohop]

Very good video again. I have also thought about the subject of how did the South-American giant theropods hunt the colossal sauropods. Also the idea of huge predators hunting in packs seems so weird and crazy to me but that just might be my tiny mammalian way of thinking. Our modern day land animals have a bit different size scale after all 😅. Btw your way of pronouncing Giganotosaurus was very surprising but in a good way. It seems everybody pronounces it differently 😁. I personally like to say giga like in gigabit, cus as a Finn it's more natural to pronounce it that way.

[@AnthonyMorris-pg9xj]

I think theropods were mob hunters more than pack hunters. Less organized, more individualized. Komodo dragons do that and so do some birds.

[@tigrecito48]

maybe it was Mapusaurus hunting in packs that triggered the arms race to make Argentinosaurus grow to such immense sizes?

[@dino-gen]

Maybe, it's certainly a cool correlation!

[@discobolos4227]

"Arms race"? To grow their ARMS even smaller than the one beforehand? :D

[@IcepickedWalrus]

I find the idea of large theropod dinosaurs practicing pack hunting to be very fitting. Especially when there were such massive sauropods roaming the lands. Hopefully, some more finds support an even greater range for such practices amongst other species 🤞🏼

[@lynnmitzy1643]

[@firegator6853]

I do think these animals might have had some kind of social behavior but i dont know if it would really be constant packs...i personally would just speculate that they mated for life and travelled together as pairs, with the only other pack members being their young which would leave at some point in subadult stage I agree that argentinosaurus would require a big group but that formation doesnt just have argentinosaurus, like you mentioned it has a lot of smaller sauropods, limaysaurus and choconsaurus are around same size if not smaller than one mapusaurus but they also still are beefy animals they would provide sufficient amount of food and judging from how ecosystems work they would also be more common than argentinosaurus as smaller animals tend to be more common overall, also another key important thing is the way sauropods reproduced, sauropods laid eggs and abandoned them but they laid LOTS of them, the biomass of sauropods in ecosystem would definitely have a lot if not more young than adult sauropods and for a big part of their life these sauropod as young would only rely in hiding, maybe outrunning (if they were more slender built than adult ones) from their predators and most importantly morality rate in population, the more individuals exist the less chance there is for you to become prey and huincul has a lot of sauropod species too Judging from all of this if mapusaurus wasnt solitary it lived in my opinion in small groups consisting of the 2 parents and their growing young and if they formed at some point bigger groups it would just be random congregation in one area of individuals that aim to take down the same argentinosaurus individual....or if they truly were more than one mated pair maybe jt could also be harem, but not a big one, for example one male and two female mapusaurus adults Or they could be territorial too and not hunt together and simply one individual was out for food while the other was back at the territory or hunted separately at the same time and met again together after hunting in the territory like many birds do which simply go hunt alone and come back to the nesting site Or it could be all of those and just depend on situation, if they were nesting they might have done this solitary hunt but still social thing but when not or when their babies were big enough to help they all hunted together or even maybe sometimes males did have 2 instead of 1 females and no doubt there would be many cases where adult mapusaurus would live alone as they either havent found mate yet or their mate died or they are not fully grown and cant mate yet but still are big to live alone like being subadults for example These are just some possibilities i wanted to suggest

[@paulwallis7586]

The predator/prey ratio is another factor. The competition would be intense. An occasional bite wouldn't manage the need for protein. This looks like a very complex mix of opportunism and environmental stresses. Also rules out scavenging as an option if the predator/prey ration is the main pressure on predators.

[@restionSerpentine]

It sounds like at the begining he is calling them sauropods

[@dragonfox2.058]

I think most theropods were pack hunters, even T Rex. JMO

[@davidperry511]

I do too

[@LudosErgoSum]

While possible, you need evidence for such a statement. If you look at our current ecosystems, there are a mix of pack hunters and solitaire hunters with anything inbetween. So in our prehistoric past it is also likely that we have the same mix of biology and hunting strategy.

[@davidperry511]

@@LudosErgoSum except most stick to said nature, canines being social, bears being solitary, yet we find fossils for tyranosaur relatives living in packs, same with carcharodontosauridae. Even Sue was found with 2 juvenile tyranosaurus rex and a sub adult, and their killers were other tyrannosaurus rex, which would imply pack behavior

[@dagoodboy6424]

I wouldnt say most. Most predators hunt alone. Either being restricted by low intelect or not enough resources to go around. But id say some tyrannosaurs and charcarodontosaurs wouldve formed groups of some kind. Although i think mated pairs would hunt together.

[@SamuRhino2023]

Tyrannosaurs have the most evidence for it, although a decent bit of the large carnosaurs would probably be pack hunting as well. Highly unlikely for Spinosaurs. As well as the Abelisaurids, There’s a lot of evidence for cannibalism with the bulldog theropods.

[@tymekzagorski9689]

Question, what are the anatomical differences btwn T. rex and T.mcraensis that allowed for the differentiation of species

[@LouisFryer-q5r]

I agree

[@rsknol]

Crocs cooperate to mob animals today but are not really a pack. The predatory bird model is two adults with juvies. What you describe sounds more like a mammal behavior.

[@shughes108]

I’d agree they hunted in pack there are so many animals that do today I hate when they say well dinosaurs brain’s where small they can’t have the intelligence to pack hunt bird are very smart for the most part and so are crocodile and alligator and all of them display mating for life no different then humans use to so I’m sure dinosaurs did something similar
