This one is actually over a year old.

Until proven otherwise, the lower lip pockets model (last and "huge chinned" ones) are the most plausible given the precendent (modern Neofelis) and the fact that most extnct saberteeth like thylacosmilids, barbourofelids, nimravids, gorgonopsids and some machairodontines all have lower jaw flanges.

I think it is deffinitivelly the most likely model for Machairodontids with large jaw flanges like Homotherium, Megantereon, Machairodus and even Amphimachairodus.

But Smilodon... is different, it has larger canines proportionally than even Megantereon and much smaller bony lower jaws flanges... Which is weird considering that it is generally assumed that Megantereon is very close to the ancestry of Smilodon. I think the model showed in the second pic might not be far from the mark for the particular genus, that or Smilodon was the only member of the group with partially exposed canines which would kept moist by dripping salivation.

Wasn't it hypothesized that sabretooths (like modern big cats) would bite off meat from carcasses 'sideways', using their carnassials? If so, wouldn't enormous droopy cheeks get in the way?

That is actually a pretty good point, in theory the cheeks are capable to retract quite a lot but how the musculature would allow that is hard to tell...

That said there was a reason why Machairodonts had portruding incissors, maybe they didn't depend on their carnasials as much as modern felids while eating?

No, the protruding incisors were there so that each tooth type could do their standard jobs without the canines getting in the way or getting damaged.

They'd have likely fed in more or less a similar manner to any other big cat as a result. With probably a bit more caution.

In any case, I can't imagine the first image could be correct. The others seem a bit more plausible.

There's a sad dearth of good Fasolasuchus pics, so this will have to do:

Was Fasolasuchus really that gracile?

I believe there is only know evidence of the snout so really it's the artist's mind in play here

Still though it is a good piece of art!

I think the angle is to blame here.

Fasolasuchus seems to be a fairly robust animal from everything I have read.

I don't think Fasolasuchus is supposed to look like a rectangle filled with the words "posted image".
