I hate to be predictable, but for me there’s no way it isn’t Smilodon.

Gotta respect those chompers...

My personal choice. I prefer Skull size and Bite force over special gimmicks. Nothing special, just the good ol Pantherine skull cranks to 11!

Considering the sheer robusticity of the skull, i would not be surprised in the least if the American lion also specialised in skull biting like that of modern Jaguar

I seem to recall reading that the American lion convergently evolved a skull to resemble that of a jaguar.

AFAIR, Atrox bones found at sites in the Central/Southern Americas, were initially seen as 'giant jaguar' specimens.

It's not really just their skull but the way their bodies were built are also quite similar to that of Jaguars. American lions are actually much more robust than similar-sized Lions or Tigers. Yes, they're not as robust as Saber tooth cats but they're still more robust than your average Lions or Tigers. They're more like giant Jaguars (in build only, not necessarily in patterns) than giant Lions. Many of the modern artistic reconstructions of these animals did not do them any justices. American lions are always reconstructed to be too thin and lanky and too much like giant Lions.

Like these very popular reconstructions for example:

[Image: Panthera-atrox3-738x591.jpg]
^ Limbs are way too thin and lanky for an animal supposedly more robust and muscular than modern Tigers and Lions.

Here is a more accurate reconstruction

^ As you can see, limbs are shorter and more robust in build. Again, an animal that is more like a giant Jaguar than a giant Lion

Actually Verdugo, P.atrox was longer-legged, fittingly so per its standing as a lion, & as demonstrated in a recent (2017) study by Chimento & Agnolin of large patherine remains found in the Americas:

'The fossil American lion Panthera atrox in South America: Paleobiological implications.'

It duly notes that P.atrox shares its
"...highly cursorial morphology..." with the extant lion, "...in contrast with living P.onca."

"In sum, the proportions & general features (of the specimens examined) are similar to P.atrox & P.leo,
& differ from those of the smaller P.onca."

Panthera leo atrox were indeed lions in form & function, but as exceptionally big cats, took commensurately large prey.

Oh ok, thanks for letting me know. But i have read from many papers describing P.atrox as being proportionately more robust than modern Lions and Tigers. I don't think i need to post the papers here, you're probably aware of the papers i'm talking about. Do you still think that many of the popular artistic reconstructions (in my post above) depicted the animal as being a bit on the skinny side and not 'buff' enough or do you think those reconstructions are fair? What do you think is the most accurate artistic reconstruction of P.atrox? (Post the image of that reconstruction here)

I mean maybe P. atrox were marginally more robust than lions and tigers. Jaguars just way differ from the larger cats in terms of proportions. I don’t see whats scrawny about those reconstructions, they look perfectly lion-like to me.

Somewhere on this site is a photo showing the really big cat limb bones side-by-side with extant panthera types.

P. leo atrox proportions are a scaled-up lion, & as we know, some lions are 'scrawny' & some are massively muscular.

The largest Atrox skeleton found was calculated to be "457kg" when alive, & so he must've been huge to look at, then.

Didn’t that one get downsized? Could’ve sworn it did.

Why did Leo atrox go extinct in the first place?  There were still bison and mooses around to serve as megafauna prey, and lions are fairly generalist as far as prey goes.  
My favorite skull is the clouded leopard skull due to its mix of smilodon and pantherine characteristics.

^Clouded leopard for me too. Nice pictures!
A pine needle fell. The eagle saw it. The deer heard it. The bear smelled it
