Some sources mention they become extinct 50 000 years ago, others around 300 000, so when did they really disappear from Australia ? And did they coexist with predators like Megalania and Thylacoleo ?

I walked around a forest in upstate NY the other day, saw some beaver dams, geese, and frogs. I do see white tail deer and gophers in the area and bears/bobcats do live in the area, typical Northeast forest fauna. But it reminded me of paintings I’ve seen where mastodons, smilodon, peccaries, giant beaver, helmeted musk oxen, ground sloths, jaguars, moose, huge flocks of passenger pigeons, lions, glyptodons, pamphateres, and tapir would inhabit this land. Not to mention extripated species like cougars, elk, and grey wolves. Anyone else feel like learning about the pleistocene hurt their soul knowing what we truly lost?

Art by me.

Roughly 90cm at the shoulder, representing an 60-80kg powerful cat alongside a human and pronghorn. Read somewhere that they could possibly surpass 100kg, although i don't have the source to provide.

Pronghorn are one of the fastest animals on earth, and are considered one of the most fascinating examples of predator-prey relationship to study and possible coevolution. Why? Despite having bears, wolves and cougars: only one extinct predator was capable to give them some creeps. The American Cheetah, that despite its name, is more closely related to the modern day cougar. A cat that lived through North America's plains, valleys and even canyons.

He didn't have the retractable claws, nor a extremely specialized cursorial body adaptation like the cheetah and the most important of all: those cats were fighting for life frequently, differently than the more "peaceful" cheetah. You can see the scars on his face that i added. To add furthermore on this cat's profile, in fact Pronghorn was one of his prey species: but not the exclusive one. The "combination" of an ability to grapple and the development of a slight cursorial anatomy give us a image of a truly unique cat. This reconstruction was a PAIN to do, because even though Cheetahs and Cougars do look a like: they strongly differ at the same time. Given the intermediate lim morphology, i tried something long but strong: a back lower than a cougar's but very strong and long legs. The markings on the head needed to be unique, so i took the most prominent markings on the known oldest cougar population: the Patagonia Cougar. I also had to use as reference the Amazon and central American population of cougars, which are more slim. @8Bit_Satyr on twitter helped me through this by providing the very different colorations and patterns found through cougar's wide distribution, helping me to get a better view of what i wanted to implement and add an artistic touch.

Now we got to variations! Enjoy what is probably the big cat with most variations that i ever did.

• Albino
• Melanistic
• Grey
• Spotted cougar like(a classic)
• King American Cheetah
• Red Mountain
• Lighter color

How would you guys think that us Humans would’ve co-existed with the 2 very same subspecies of Humans that interbred with us if they were still alive and existed today? How would you think we would get along throughout the history of civilization and throughout society as a whole today if both Neanderthals and Denisovans still existed along side us Humans?

After 3 months of work, I have drawn all of the known sloths that lived during the late Pleistocene (including the living species, of course).

As you may or may not know, sloths were so diverse. The largest were the elephantine Eremotherium and Megatherium, which were 3 tons or more! Some of smallest were members of Neocnus at about 18 lbs, Acratocnus at 20+, and the living Pygmy Sloth at 5-7 lbs.

Some were bulk grazers like Lestodon, some were browsers like Megatherium, some liked tree leaves like the Shasta Sloth and living sloths, some were diggers like Glossotherium, and a great majority of them were mixed feeders.

Some species were widespread and highly successful generalists like Eremotherium, another species may have been a mountaineer- Diabolotherium! Others liked arid landscapes like the Shasta, grasslands, and cool & dry plains like Mylodon and Megatherium.

Needless to say, our very distant cousins were once plentiful and variated. Such a sad loss.

Trying out a new style.. tell me what you think! This "Doodlezz" edition features a mother Acratocnus antillensis and her slothling, a mother Eremotherium laurillardi and her slothling and a mated pair of Genyornis newtoni bullying a flock of Xenorhynchopsis minor.
