9:20 this is actually wrong. The reason why the short face bear was so rare at the tar pits is because it lived in more open habitat areas the tar pits, mostly take place in the forest and areas. That’s why there are sabertooth cats and dire wolves at the tar pits more than short faced bears and American lions.

[@Dramn_]

Mostly take place in the forest and what areas?

[@SuperTah33]

The reason given by the authors of the paper is that all the three bear species recovered from the Tar Pits were likely not regularly competing for carcasses (at least not at the rate the hypercarnivores were competing for said carcasses), with lower population densities to boot. Arctodus simus was recorded at its baseline continental abundance, though from a shorter time window.

I think with the weight differences you would have a similar interaction to how that pair of lionesses encountered a honey badger. It might just end in the Carno deciding it isn't worth the trouble

[@albino-fish]

This is interesting regarding the size of Arctotherium. Copium Rex actually had a similar thing going on with its femur, the femur was actually shorter than Stan, Sue, and Scotty’s femur but Copium’s was girthier. While Arctotherium’s humerus was shorter than Arctodus by around 2cm it was also girthier by around 2cm as well. I’m not a scientist or anything but it’s something to think about.

[@denistyrant]

The size estimates based on femurs likely weren’t the same between T. rex and bears however, because something like Theropods iirc, you’ll go with the width of the femur not the length. Looking at the study and the post, using humerus length seems to best way to estimate the mass of the bear.

[@albino-fish]

@@denistyrant both the femurs and humerus are weigh bearing bones so I think while there will be some differences in equation I still think it would have similar effects. There’s also (Nicolás E Campione et al 2012-A universal scaling relationship between body mass and proximal limb bone dimensions in quadrupedal terrestrial tetrapods) this is what is said in the conclusion “The conserved nature of the relationship between stylopodial circumference and body mass suggests that the minimum diaphyseal circumference of the major weight-bearing bones is only weakly influenced by the varied forces exerted on the limbs (that is, compression or torsion) and most strongly related to the mass of the animal. Our results, therefore, provide a much-needed, robust, phylogenetically corrected framework for accurate and consistent estimation of body mass in extinct terrestrial quadrupeds.” I also couldn’t find anything on humerus length being a better indicator for mass estimates in general let alone for bears. I personally think only using one equation to estimate an animals mass would also yield a lower sample size. versus multiple equations to find the median/mean mass, which would lead to more accurate or reliable estimate imo.

[@mhdfrb9971]

The whole two ton size estimate for Arctotherium angustidens is far fetched for several reasons. The bone used for the size estimate had been broken and then healed, leading to a far greater diameter than it otherwise would have, thus giving false results when put into the equation. It also ignores that there are multiple known Arctodus bones of the same limb element no less, that are larger than the specimen used in the study, and come from animals that only weighed around 1000kg, meaning the individual bear used to get the 2 ton size estimate would actually be smaller than 1000kg. The equation was also developed using obese brown bears in captive settings, meaning it is effectively useless for calculating the mass of non-obese bears. So, from what material we have, Arctotherium angustidens likely only weighed around 800kg-bigger than any living bear save for the record sized polar bear, but smaller than Arctodus.

[@albino-fish]

@@mhdfrb9971 “The 2ton estimate being far fetched” so you do agree with the paper! Because the paper says itself “The highest predicted value is probably unrealistic” aka the 2ton estimate. Yes the specimen in question had heal damage but what you fail to mention is where on the specimen. The parts that were damaged were the caudal border and deltoid crest. Not the shaft of the humerus. As I pointed out to the individual before you. diaphyseal circumference of the major weight-bearing bones strongly related to the mass of the animal (Nicolás E Campione et al 2012).I have yet to see a Arctodus specimen that surpasses the Arctotherium’s humerus in circumference. But if they are as common as you say they are then it should be no problem to mention them. Which equation was based on an obese brown bear? There’s 6 different equations if you didn’t know, so one being unreliable probably wouldn’t change too much. Was it the 2ton estimate or the other three that put Arctotherium above 1,600kg. So many to choose from lol. So, from one equation from one measurement used (length) of the humerus you guesstimate that the animal weighed 800kg despite the fact that the lowest estimate provided was 983kg so even the lowest estimate of Arctotherium would still make it slightly than the average Arctodus.

[@mhdfrb9971]

@@albino-fish The 800-900 kg size estimate is for the largest known Arctotherium angustidens individual, it’s not the norm for that species. An average of 550-650 kg seems more reasonable for them which is around the same as male polar bears. They were certainly huge bears, we just don’t have the material indicating they matched or surpassed Arctodus simus.

The short faced bears actually 6 feet tall at the shoulder and 11 feet tall om to legs

[@fgialcgorge7392]

If they were close to equal in size I think it's a 50/50 shot as to who wins. Carnotaurus could land a bite on arctodus front limb and from there it might be game over depending on the bite or maybe land a bite on the neck. On the other hand bears regularly bite the ever loving shit out of each other and fight like Olympic Greco-Roman wrestlers. They're much more stable bipedally than given credit for here. If the arctodus came rushing on all fours and stood up quickly as bears often do, it could bite the carnos neck with it's arms wrapped around. Bears power is often severely underestimated in these types of videos and to this day we have no way of accurately measuring their strength, let alone an extinct bear. Just look at the Sloth Bear vs Bengal Tiger. Yes Bengals do kill them but Sloth Bears often return the favor or scare the Tigers off because it's not worth the risk but then they go drop a 2800lbs Guar. Like I said, if it's close in size 50/50 is probably the most likely outcome, or they just give each other a wide birth.

[@denistyrant]

Wrong, there’s multiple problems with this. While yes, they can stand up on their hind legs, the stability isn’t going to be as good as something like Carnotaurus, especially since they don’t have a large muscular tail to keep them stable. This would leave them vulnerable to being knocked over, especially since when intraspecific conflicts, bears tend to get rag dolled when they’re both standing on their hind legs. Something like Carnotaurus would have far better stability when it comes to bipedal stance, and it’s not even close. Now for the biting, even with that being said, bears aren’t adapted for landing quick and fatal bites like Felids, and to land such a well placed bite, Arctodus is going to have to keep Carnotaurus in a good place. One could say sure, the bears strength is underestimated but so are dinosaurs and in general macropredatory reptiles like crocodiles, especially when compared to bears. I should mention as well unlike canine teeth, ziphodont teeth isn’t dependent on going to softer areas such as the neck, they can go for any area, as along as they get a good bite in, it would cause serious bleeding for the animal.

[@br3hbmc79]

I wonder what Carno's resting heart rate would be? Reptiles generally tend to have lower metabolic rates than mammals, leaving them prone to exhaustion after quick bursts of energy. Caimans have been observed to have resting heart rate in the single digits that rise to the 30s and 40s of bpm when sighting prey. Conversely, polar bears have a resting heart rate in the 40s and 50s of bpm. This would likely increase during predation and combat, but I haven't found numbers on that. This would make a big difference in a prolonged fight, with the reptilian Carno tiring out after it's initial attack/struggle. Fights between similarly sized male Grizzly bears during the mating season can be prolonged encounters. I've seen footage of some lasting well over 10 minutes. Now I'm unsure if this means the short faced bear would have more stamina than the Carno, given the larger size of the Shortface compared to modern bears. But if the stark contrast between the metabolic rates of mammals and reptilians applied in this fight, I'd say that the Carno would have a smaller window of opportunity to win than the bear. Now if the Carno bore a similar metabolic rate to living terrestrial birds like Ostriches or Cassowary, which have resting bpm around the 40s and 50s and a range similar to that of mammals, there wouldn't be as much of a discrepency. Also for some reason, six flags new england says Carnos may have hunted in packs, although I can't find any other support for that claim. If that was true then the bear would lose as there would likely be more carnos.

[@denistyrant]

It’s very likely Carnotaurus had higher metabolic rates than other reptiles. It was at least an mesotherm, with some studies even suggests that suggests that many dinosaurs were endothermic, having a metabolic rate higher than mammals and closer to that of birds.

[@thegametroll6264]

The video literally mentions why they went with Arctodus simus and not Arctotherium angustidens

I feel like a good couple swipes from the bear would make the carno retreat since it would think the fight isn't worth being badly injured

[@TheOverseerDebates]

That is how a real situation would go. Predators would not risk their health over nothing, but in a battle to the end, I think the Carno would take it.

[@jackdeering9301]

@@TheOverseerDebates Agreed, great video boss

[@srobeck77]

Generally yes, but under certain circumstances sometimes predators will risk fighting to the death. When starving and close to death or to protect their young for example.

Carno's big advantage would be gone after the initial charge, if the fight ever goes to the ground then the bear would have advantage. In short it would be decided in a moment, despite being a drawn out encounter.

Carnotaurus negs. 2.1t Theropod with bone crushing jaws and thick hide against a 1.1t Bear who has shorter face compared to an average bear.

[@loganshark667]

Realistically: bear slashes Carnos eyes whilst carno attempts to restrain bear. Carno is doomed to die. Even more realistic: carno decides this isn't worth it and runs off.

[@panagiotismagos3649]

@@loganshark667 yeah because bears are known to be precision strikers that go for the eyes (something that even humans that use their fingers every day cant do). Sure man

[@loganshark667]

@@panagiotismagos3649 I mean, think about it, a carnotorus is going to attempt to bite the bear, which requires putting its head in reach of the bear. by the placement of the eyes of the carnotorus, It's most likely going to either hit in the eye or rather close if our short faced bear decides to go for a slap or slash... if the bear fails to slash the eyes out of the carno, it's not gonna end well for the bear... But realistically, the bear should end up ripping the carnos' eyes out... unless the carno bites the bears arms, which would make everything a lot more complicated... Unless I'm forgetting something important...

[@spinosaurusstriker]

​@@loganshark667you are forgetting many things important, the size for example in the first place the bear is never going to precision strike a carno thats not just how they work what it will happen is that the bear is going to strike the dace of the carno were the damage will be superficial the size difference is too much. After the second punch the carno is going to grab one of the paws of bear and serilusly mangle it or drag the bear as a whole.

Who wins a Sabertooth Tiger or a Polar Bear?

[@TheOverseerDebates]

That’s a good match up. Off the top of my head, due to the size and stamina advantage, I’d give it to the polar bear

[@mcafreee4770]

Amazing video and I agree with the outcome but he did get a few things wrong about the carno. For starters the carno was not good at quick turns quite the opposite actually it’s tail was wide and thick but did not have a lot of maneuverability which is what most therapods rely on to turn. Second of all it was not an ambush hunter taking in the fact that it could not turn very quickly means it most likely hunted on open plains where it would pretty much race its prey and bite at it in quick succession until it dropped not one large bite to drop it in one go. And finally I pretty much just said it but it did not rely on its bite force but rather its bite speed to take down prey.

[@maxgremer7638]

The point is that I don’t see where and how the bear could get a kill strike actually at all

Who won?

[@samuelmaia5089]

I honestly believe that bears are nature forces and even smaller they would find a way to win

[@wontolla7403]

i think the carnosaurus would win 8-9 out of every 10 encounters. we got to remember that the momentum of the carnotarus would also be transferred to the bear, meaning that it most likely would be flung backwards if it got hit, opening up opportunities for the carnotaurus to attack

[@stanisawzokiewski3308]

I wonder how a carnotaur would react to a bear roar. Simce dinosaurs likely didnt roar like in movies it might just scare it of

[@srobeck77]

I kinda think bear roars are very underwhelming. Lions have a way more unintimidating roar.

[@abdulazizrex]

Isn’t it more agreed upon that while Carnotaurus was pretty fast it wasn’t good at turning, and that it had a weak but fast bite.

[@denistyrant]

Those were before the bite force estimates came out, for turning, not really, especially since stiffer tails were better for agility iirc

[@shaheedreid1849]

Barinasuchus vs carno? Who would win

[@TheOverseerDebates]

That’s an interesting match up. Haven’t looked too deeply into Barinasuchus, however, I think it fairs a lot better than Arctodus simus.

[@ammarihsanmohamadalfianmer3357]

how about carnotaurus vs bull

[@MaliciousMollusc]

I would say Carnotaurus would win because the jaws inflict much bigger wound in 1 bite. Arctodus is strong for sure, but has lower DPS. Its claws and bite couldn't inflict damage as efficiently as one big bite.

[@KompressorV6]

I think a lot of texts overestimate the size/weights of a lot of these smaller therapods. Bears are extremely powerful. Like how would it attack the bear. Just charging it? It has literally no arms. Imagine going after a bear with your face. Lets not act like Carnotaurus had some huge jaws either. There's like one almost complete skeleton of Carnotaurus and even then it's not complete. If they actually were 4k lbs then maybe yeah, but A 1500lb plus bear would not be an easy meal. Movies have made people believe these things were huge.

[@ANotSoPopularMan]

The carnotaurus from Dinosaur and Terra Nova are fucking MASSIVE. Iguanadons are compared to Allosauruses in terms of size and weight. A carnotaurus dwarfing that and standing up to a sauropod is insane. The carnotaurus in Terra Nova is completely faster than a jeep going full speed as it was able to catch up with it in under at least a few seconds. Fiction and movies do carnotaurus clean.

[@wesselvanderlinden3832]

A 1.3 ton bear could probably wrestle an even heavier carnotaurus with ease. And once the carnotaurus is on the ground it's over. The bear is too intelligent and knows how to fight.

Unless it’s proven using humerus shaft is better than using humerus length for bears, A. angustidens is going to lose even worse than A. simus

[@lewisbean4250]

Except as said in the video, thr giant 1.5+ tonne estimate is erroneous as the individual’s bone was injured and reheated, making the radius thicker than it should be, and was scaled from overweight captive bears, which isn’t very reliable.

Assuming the bear doesn't get immediately chomped, one could climb a dino like a tree. Dino just better be good with the chomp and shake

[@srobeck77]

I dont think the Short faced bear would have the agility to do that. Keep in mind, its way heavier than your average bear. Also has longer legs too relative to its body size, which would further decrease its climbing ability in favor of faster top run speeds.

[@websdaspider8811]

Carno was designed for speed and eating smaller creatures. If the fight is tipped in the bears favor the carno can just... run away

[@philipmurphy2]

Dinosaur time

[@tomcross3000]

I think short faced. longevity, power, density, agility, brains. The bear has denser fur and more fat- harder to land effective hits. The bear has long, swinging, heavy limbs tipped with foot long claws- the carno has no claws or arms The teeth and jaw of carnotaurus were weird- curved in an odd angle and the jaw pointed upwards, not much is known about bite power, but the bear has maximum power in its bite with the shorter, more compact jaw- nothing by itself, but it has foot long claws to mess around with!

[@wontolla7403]

he litterally mentioned that studies suggest the bear had a harder time turning while running, also other studies suggest the carnotaurus was exceptionally agile while running. there are studies about carnotaurus having osteoderms, kinda like crocodillians for defense, meaning it would be a lot harder to pierce the skin and damage with ex. claws. also some studies suggest that the reason carnotaurus jaw was angled was because it would allow its long straighter teeth to do like dagger and stab into its victim, cutting away flesh as it tore out chunks of flesh, making its victim bleed massively.

[@tomcross3000]

@@wontolla7403 short faced bear studies? from 1993 or 2003, which weren't really studies at all? the guy not even having proper quals in osteology, myology, kinesiology to make that determination? All this basic biologist/ecologist did was draw vague comparisons to modern animals and say it was too big to be good at running or eating big things.. In other words, a jack horner. Carnotaurus had some osteoderm bumps, that's different to being covered in scuts like a croc. Its not going to make you safe from an arm as thick as a log and as long as a person, tipped with foot long claws, slashing away at you. Look at real protection- layers of dense fur and then layers of fat which small carnotaurus teeth aren't going to get through with one bite, and the bear is not ging to be staying still, it will counterattack with wild swings, causing its own blood loss.

[@honeybadgerbomb4469]

I'd put money on Carnotaurus, simply so far larger, as well as having taken down prey like Amargasaurus adults, which would have been very tough to hunt. Its teeth and jaws make up for its potentially mediocre bite force, allowing it to easily grab and rip apart any area of the bear it goes for.

[@tomcross3000]

@@honeybadgerbomb4469 No proof that it hunted those prey items at all and it stands 2 feet shorter than the bear.. its teeth are small and cannot penetrate layer upon layer of winter fur coat, undercoat, fat and muscle.
