Megafauna Today

Most specifically, Pleistocene megafauna

>>2407122
most of the animals you know of today are megafauna.

you are megafauna.

>>2407124

Sure, by definition so is any animal weighting 44 kl and up. I mean things like mammoths, great flying birds, gigantopithecus, and such.

What about large ass reptiles?

>>2407125
realistically atmosphere and climate had almost nothing to do with their extinction.

>>2407125
then say that instead of making it seem like you're using words without knowing what they mean

>>2407129

irresponsible use of words, I admit

>>2407128

do oxygen leves have nothing to do with the possible size of fauna? I thought modern atmosphere had less oxygen in it, which would explain smaller flora, or so I read.

Yes. Most of the megafauna died off because of human hunting and habitat disturbance, not because of climate. They co-existed with all modern species and most of them could still survive today if we brought them back. Not all of them lived on cold steppe, plenty of them lived in warm climates and would do fine.

Oxygen levels only affect the size of insects and other arthropods, not verterbrates like mammals. Many of the biggest dinosaurs lived in periods when there was less oxygen in the air than today.

The loss of huge animals damaged most of the ecosystems on land severely. They would be more resilient and productive if we could bring them back.

Yes.

>the Wrangel Island mammoth herd

The woolly mammoth has a fossil history on earth of about 2.5 million years, and has survived hotter periods than today.
The time when mammals in general were larger than any other time before or since have been the hottest periods of mammal history.

It's so sad that it sounds like a stereotype now, but the biggest threat to animals of any size is man. Of course not just one of any man, but man itself.

No, nothing can live here.

it'd be exceedingly difficult.
large animals require large territories to sustain their feeding.
Human settlements have isolated potential habitats for megafauna from one another.

>>2407128
desertification certainly reduces their access to food

so modern elephants, rhinos, lions, horses, and camels all originally came from north america?

can you post extinct animals like in the OP instead of modern animals?

The size of animals is on a downward trend and will continue on this trend as long as humans continue to appropriate more biomass for itself. It's possible, but much less-likely after our species' advent.

>>2407472
Point is, they still exist in our modern climate.

>desertification certainly reduces their access to food
yep but so does the temperate zoned being under hundreds of feet of ice. They would've had to move north is all.

Well your mum's alive innit

>>2407128
Obviously but that doesn't change the fact that at the time they were alive those factors were much different

Wild/feral mustangs do fine in the wilderness of North America, without the need of human interventions.

Although, their greatest predator is seemingly Pres. Donald Trump

>Obviously but that doesn't change the fact that at the time they were alive those factors were much different
climate was much colder because there was less CO2 in the air, but other than that there was no major difference.

I think OP is referring to the mistaken idea that there was more oxygen then. That's not true.

Yes, ur mom is living proof lmao.
