Great Porn Dragon: Still, though, if you want to get a rough idea of what kitty might have looked like in real life, here's at least one reconstruction of its kissing-cousin Megantereon:


Cool...  Here's one with perspective:

And interestingly (reading the paper) they had actually originally considered Rhizosmilodon to be a fossil of Megantereon (another more obscure sabertoothed cat)--and this isn't quite an ancestor but more of a rather primitive dirk-toothed cat (one of the two major groupings of true sabertoothed cats, the others being scimitar cats like Homotherium).

(Innit cute? :D)

Rhizosmilodon's other kissing cousin, Smilodon fatalis (aka the North American dirk-toothed cat):

(Yes, you may notice a bit of a trend--no stripes. :D  It's now felt that sabertoothed cats were probably spotty, not unlike snow leopards or young lions or pumas.)

And just for comparison's sake, my favourite sabertoothed cat (the American scimitar cat, Homotherium serum):

(Yes, yes, I know, its fangs are...understated compared to Smilodon, but still.  I like this deadcat)

"Homo-therium serum" name looks like it translates to "radioactive man juice."


Or a great name for a emo punk band.

Actually, yes, it is really cute!  Look at that tummy!  Who wants tummy rubs?!

Cool, a new (old) machairodont :D

In all truth--despite the debate on kitteh predating young-earther claims re the planet's age (ALIEN KITTIES! :D)--this is actually a pretty significant discovery--shows that the true sabertooth cats probably evolved here in North America.

Plus we may have caught a glimpse of sabertooths when they were starting to get "sabery"--the teeth are a bit more sabered than clouded leopards (which may evolve into the next clade of sabertooth cats if they can manage to not go extinct in the meantime) and it's only about puma-sized (yes, pumas are Big Kitties, but still little compared to, say, Smilodon which had species that are among the biggest kitties to have existed--yes, bigger than tigers, big enough that you could practically ride on them a la He-Man if kitty wouldn't chew your face off first).

/yes, damnit, I like machairodont kitties, even if they are deadcats.  Also tend to like the more obscure ones like Homotherium
//if we can get to the point of turning critters that died out in the Great Pleistocene Extinction into lazarotaxa, I say we work on bringing machairodonts back.  And then the Nashville Predators can "adopt" and sponsor the Nashville Zoo's own Smilodon pride :3
