[@dmdizzy]

Consider this: wolves don't use their claws for attacking prey. Their claws are primarily for traction while running. I think hooves would serve the same purpose, and so wouldn't be a disadvantage - in fact, they might even prove to create an even better cursorial hunter, assuming an animal with a bodyplan facilitating that were to develop.

[@bkjeong4302]

This may actually be the case with entelodonts, which had very cursorial leg proportions plus other limb adaptations associated with cursoriality.

[@jackalhead7433]

That's not a 100% good comparison Wolves and Andrewsarchus may have a similar body structure but Wolves are pack hunters and quite intelligent too which means that they can hunt and wear down and a prey together It is unknown whether Andrewsarchus was a pack hunter given the animals large size though probably it wasn't and I doubt that it possessed the same intelligence as wolves Most likely it was kleptoparasite

[@LeChristEstRoi]

@@jackalhead7433 Not necessarily a kleptoparasite. You don't need to be a pack a hunter to successfully catch a prey, nor you need to be super intelligent (snakes, crocs, gators...aren't the smartest animals around, but they are successful hunters.) Cats, tigers, leopards, bears...hunt their prey alone. Even a lone wolf is capable to hunt down a prey as long as it is not too big to handle.

[@jackalhead7433]

@@LeChristEstRoi"Snakes" crocks, gators," Do not have the same body structure with the andrewsarchus and also they occupy a certain ecological niche that's why they are so successful A lone wolf is still smaller and more agile than an Andrewsarchus thus makes it easier to catch prey and doesn't need that much food to preserve itself plus wolves are also scavengers especially when they are alone and can't successfully hunt bigger prey

[@LeChristEstRoi]

@@jackalhead7433 I wasn't saying that snakes, crocs, gators have the same body structure that Andrewsarchus, the point is that an animal doesn't need to be super brainy to be a successful predator, nor it has to hunt in pack to be able to catch and kill something. The brown bear is less agile than the wolf; is stll capable to hunt down preys, the same with polar bears...the anaconda is dumb, bulky and slow as hell, but it can catch deers, pigs...! because as you said those predators may occupy different niches, and/or they may preferentially target different species more adapted to their body structure and capabilities, and/or they have different hunting behaviors and strategies. We can deduce exactly the same about Andrewsarchus. It wasn't intelliygent? Lots of predators aren't that smart and are nonetheless capable to catch preys...it was bulky and somewhat slow? Lots of predators are bulky and slow but they can overcome this by specifically attacking preys which are also slow...or by using ambush tactics. Tigers a slower and have far less stamina than most of their preys...It was a solitary animals? Lots of predators are also solitary...it's exactly the same with this Andrew dude! It could have occupied a niche, adopted specific hunting tactics, preferentially targeted some specific preys species...to overcome its supposed relative slowness, dumbness...or maybe as you wrote it was a lazy kleptoparasite or scavenger.

[@macnutz4206]

I used to take care of and occasionally worked a horse, a Clydesdale, that intentionally ate frogs in the field. She did it often enough that I and others saw her doing it on several occasions. She didn't hunt them but if they popped up while grazing, she altered what she was doing and snapped up the frog. Then she would shake her head and make odd grunts before returning to the grazing. Another farmer told me that he had seen a mule that did the same thing. I found it quite disgusting the first time I saw old Cranky eat a frog. Crank had a well deserved name so I said nothing to her.

The problem with most entelodont depictions is that based on its skull Andrewsarchus was more basal, ie had not the derived pig-like body structure of an entelodont

[@chifuyuko]

With such a large skull one could deduce it would have had an incredible jaw strength. This would fall in line with scavengers like the hyena, being able to consume bone marrow...

[@rxg9er]

Hyenas don't scavenge more than any other predator. They eat marrow because there's so many mouths to feed in each clan. Early naturalists called them scavengers because they appeared to be scavenging off of lion kills. More research revealed lions were stealing hyena kills and forcing hyenas to scavenge off of their own kills. Though if the opportunity arises hyenas would gladly steal a kill from lions. Scavenging is a terrible way to find food. Vultures fly hundreds of miles a day looking for carcasses. A true scavenger is an animal that can cover long distances and survive off of very little food.

A lot of the more hippo-y ones were shown too, which is the kind of integument you see on many reconstructions of entelodonts. If it was more of an active carnivore it may have had more carnivore-esque coloration for the same kind of camouflage, and if it was a sort of basal, somewhat smaller relative of them in a group where fur is basal and lost in the more derived relatives that are either more aquatic or bigger, then one of the contributing factors to a superficially wolflike appearance is probably still justified.

I think it's more likely that ancestral artiodactyls were a grade of hooved carnivores or perhaps omnivores- giving rise to mesonychids, andrewsarchus, whippomorpha, etc...some lineages of which evolved omnivory and then herbivory. Herbivory is a more specialized trait than carnivory so it makes sense the ancestral animals would be carnivores- it's harder to reverse specialization. This is supported by the fact that ungulate relatives, Ferae, are also carnivores, and different herbivorous artiodactyls like tylopoda, ruminantia, etc have different mechanisms of fermentation. In general the obsession with monophyletic groups and synapomorphies leaves out the information carried by evolutionary grades...it's a mistake

Claws may not be necessary if you have a super nasty, over-sized head, that can just smunch the hell out of anything, without gripping. Note that pigs can become quite carnivorous. They will definitely eat your chickens, no claws needed. If you threw a rabbit or a deep into the pig pen, they would eat those as well -- again, no claws required. Because big, very strong, crunching head. Andrewsarchus strikes me as sort of a pig analogue -- a big, athletic, relatively high-endurance pig.

Well cats are everywhere because they won...then they evolved a branch to become symbiotes with humans called house cats lol. Andrewsarchus was a beast though.

I'm OK with giant carnivorous pigs not being a thing anymore.

[@rarrireps2957]

This evolved into a pig, a pig has hooves that it can't use so it becomes a scavenger.

[@Dr.IanPlect]

No, this did not evolve into a pig.

[@deddasna]

it has no living descendants.

Andrewsarchus the largest carnivorous mammal? Let me introduce you to Balaenoptera musculus, another Artiodactyl, and in this case somewhat closely related to Andrewsarchus. It's from the Quaternary not the Eocone, and it can reach 30 meters in length.

8k subs in how many days! Love the content glad the algorithm showed me you’r channel

[@skyem5250]

The largest mammalian predator is Balaenoptera musculus. I'm pretty sure Osborne would have known this because they're extant.

[@Atari11000]

Thank you for putting the names in the video and when you didn’t you said something else like hell pigs. Please make more of your videos like this

[@Raylen_Fa-ield]

Maybe the vooved predator used then to stun pray before biting. Imagine a leaping diving hoove smack

[@noammkw3770]

i wonder if one of these one day was like "man, i hope my grand-grand-grand-grand-grand-grand(...) kid is gonna be 30 meters long"

[@untro7287]

5m does seem pretty wild for a predatory land mammal

[@HorrendousCaliber]

Thats an extremely dangerous apex predator if so

[@chrisrus1965]

How could you pass up an opportunity to use the word "whippo"?
