Smilodon populator drawing 2 by Jagroar Smilodon populator drawing 2 by Jagroar
This is a draft sketcing of "The Nature's Ultimate Grappler"(completed as a drawing).

Smilodon populator (1 million-10,000 years ago); occurred in the eastern parts of South America and was the largest species of all smilodontines.

:Size:
It was more than 1.2m (48 in) high at the shoulder, 2.6 m (100 in) long on average and had a 30 cm (12 in) tail. With an estimated weight of 220 to 470 kg, and exceptionally large individuals estimated to have exceeded 500 kg(Carbone et.al, 2007), it was among the heaviest known felids. Its upper canines reached 28 cm (12 in) and protruded up to 17 cm (6.7 in) out of the upper jaw.

:Morphology:
Smilodon possessed a short tail, long muscular neck and hypertrophied upper canines. The lumbar region of the back was proportionally short, and the lower limbs were shortened relative to the upper limbs in comparison with modern pantherine cats, suggesting that Smilodon was not a very fast runner. Smilodon also had a relatively longer calcaneum or ankle bones.

Based on analysis of plant fossils from the last ice age, many paleontologists now believe that most Smilodon species had the dappled coat of a cheetah or bobcat. This coloring would have helped the cat blend in with the vegetation that was common at the time.

The South American S. populator had higher shoulders than hips and a back that sloped downwards, superficially recalling the shape of a hyaena, in contrast to the level-backed appearance of other two Smilodon species and Megantereon, which was more like that of modern cats. However, while its front limbs were relatively long, their proportions were extremely robust and the forearm was shorter relative to the upper arm bone than in modern big cats(the robust male jaguar is the closest in forelimb propotions to smilodontines), and proportionally even shorter than in S. fatalis. This indicates that these front limbs were designed for power rather than fast running, and S. populator would have had immense grappling strength in its forequarters.

:Hunting and Extinction:
Smilodon’s hypertrophied upper canines were probably built more for slashing than stabbing. Despite being more powerfully built than other large cats, Smilodon actually had a weaker bite. Modern big cats have more pronounced zygomatic arches, while Smilodon had narrower head bone and zygomatic arches which restricted the thickness and therefore power of the jaw muscles, and thus reduced Smilodon’s bite force.

Smilodon more probably used its incredible upper-body strength to wrestle prey to the ground, where its long canines could deliver a fatal slashing bite to the throat which would generally cut through the jugular vein and / or the trachea and thus kill the prey very quickly. This killing technique may have made Smilodon a more efficient killer of large prey than modern lions or tigers, but also made it more dependent on the supply of large animals. This highly-specialized hunting style may have contributed to its extinction, as Smilodon’s cumbersome build and over-sized canines would have made it less efficient at killing smaller, faster prey if the ecosystem changed for any reason.

Ultimate grappler would be Thylacoleo (opposable thumbs, much larger and deadlier claws), sorry.

Nah the ultimate grappler would be xenosmilus, much larger and stronger, opposable thumbs, more dexterous digits and longer claws as well as more mobile hips and semi-plantigrade stance.

Does it have a specially reinforced tail that acts as a third rear leg to balance the animal while it grapples? The marsupial lion had that.

Also, I doubt Xenosmilus had claws bigger than those of Thylacoleo.

Yes it's claws were much larger, it was also a much larger animal. And no it doesn't have that, but what it does have is much thicker humeri, much more dexterous paws, a much lower brachial index (this indicates overall mechanical advantage of the arms), sharper claws that provided a better grip on whatever it happens to be grappling, a more robust tibia, a sloping back (something that thylacoleo lacks completely) which provides greater advantages in pushing and pulling, as demonstrated by the bears and hyenas of today, a thicker trunk which provides for more strength and stability, more flexible hind legs which lets all of it's limbs contribute to grappling, and finally a more advanced brain that lets it gives it better coordination reflexes.

The brain thing is nonsense; as it turns out, brain size or structure (both absolute and relative) tells nothing about its owner or how advanced said brain is. As a rule, top-level predators are all highly intelligent animals, and both mammals fall in this category. 

Why on earth would Xenosmilus have sharper claws? You do realize Thylacoleo also has retractable claws and sheaths to protect them?

Much more dexterous paws? Against something that has an HUMAN-LIKE OPPOSABLE THUMB?

The other points are correct though.

First off, holy hell you're fast. Second off, xenosmilus also has opposable pseudo thumbs...although I was referring to it's hind paws in that statement but I did a little more research on thylacoleo and it seems to also have thumbs on it's hind paws like Xenosmilus so I'll retract that statement. Anywho, I said it has sharper claws because while thylacoleo had retractible claws like felids they had much less curvature and hooking ability, aside from the thumb claw of course. I included the brain bit because carnivorans adapted larger brains than creodonts and marsupial predators that gave them better coordination and reflexes in exchange for generally smaller jaws and jaw muscles, with thylacoleo being a marsupial and xenosmilus being a carnivoran I assume that they are no exception. I'm of course not saying that thylacoleo is dumb because you're right, as a mammalian apex predator it likely isn't, but it's likely that it wasn't as coordinated or reflexive as xenosmilus. I can give you the link to this study if you'd like.

Fair enough on the claw sharpness. The curvature does seem to be a lot less.

So the brain thing is not about intelligence (thank god that it isn't) but coordination? Link pls because animals much less closely related to carnivorans often do have a high degree of reflexes.

Nice Smilodon picture Jagroar. There's one serious dilemma that's haunting me altogether... You think Ice Age men made cave art with these big cats?

Hey, so glad to talk to ya again DC;] is it from library?
I want to think it as being completed as a drawing for now, but certainly will paint it when I'm ready(I'm not in harry lol). I'm kind of satisfied with its morphology, hopefully u too.

I have question:
Do you think that Smilodon Populator could Beat Machairodus Kabir?

Jagroar Featured By Owner Jul 3, 2010   Traditional Artist
Thaaaanks lol, I'm very glad that a saber-toothed cat fan come to like this piece.^^
Well I think S.populator would take that fight more often than not, due to its superior grappling strength and killing power(just my opinion).

I totally agree~ Smilodon with a highly muscular body would take on machairodus kabir (no matter what size it is) any day:)

Thanks, it's great to hear that you like this piece, especially if S.populator is your favorite among prehistoric beasts.=)
I kind of intentionally omit the pupil so as to make it look more "fierce and deadly" lol, but may put them back when I color him. :)
