It also clearly demonstrates lack of knowledge about feathers. Feathers don't trap heat in the manner of mammalian hair, so they're useful both for warming up the animal and cooling it down.
Even if it worked like mammalian hair, shouldn't we be portraying Megatherium with naked skin if this was true ? ;)

Besides, even in current mammals there are ways to get rid of warmth using hairs, elephants do this with their hairs. :)
And people misunderstand why elephants and rhinos are hairless.

it is not because they're "big" its because their ancestors were semi aquatic creatures, plus they often start regrowing fur whenever things get a little colder.

and talking about sloths, which are similar sized, we have many ground sloth skin material and they're by average WOOLIER THAN MAMMOTHS even tough the species we have fur of lived at places such as...

the northeastern Brazilian caatinga:

or the Mojave desert:

see, theres many reasons animals lose integument and size isn't one of them

I guess that also may have something to do with the fact that sloths usually had a pretty slow metabolysm (maybe not so much on ground dwelling spcies, but still...) so I guess that they're biggest problem thermoregulation problem wasn't to stay cool...

they were still large scale warm blooded creatures, slow metabolism or not, and while true they probably wouldn't care too much about thermoregulation as your average elephant, still, its the freaking nevadan desert, you'd expect atleast some loss of hair if size and integument loss were related to thermoregulation.

I thought all the ground sloth fur we had was from species in temperate climates? I've pictured the tropical giant sloths as hairless or with reduced coats, and the colder climate species with thicker ones.

nope, infact most fur comes from tropical south america, namely Brazil and northern argentina, which were as hot then as they are today.

and theres of course fur from species such as the northern Nothrotherium species from the mojave desert.

the only species we have fur samples for temperate enviroments is mylodon, and yet, that same species also inhabited fairly warm climates up north.

Long haired species in hot climates doesn't surprise me.

Hell, bison habitats get pretty hot for much of the year, and they're really hairy. Not as hairy as say, Musk Ox, but bison are still huge animals from sun exposed plains that aren't leathery beasts.

I'm kinda annoyed by how people often use marine animals in environment different from those they were found. Just because they could swim it doesn't mean they were necessarily spread worldwide.

Indeed, infact many things decide if an animal is gonna loose integument or not, size in particular is not one of them

I could infact bring forth even more examples such as brown bears of the gobi desert and black bears on arizona and Mexico.
