You told: " The second pic is a four set canines of an adult male African lion, albeit a large male. And its weight formula for each individual canine should be 0.3 + 0.3 + 0.2 + 0.2. So the upper canine of a large male modern lion should weigh about 80g, a little more than half of a large male cave lion. "

Yes, I have retained the extant felids' fangs weights, but I would have never expected that the difference between an actual lion and an extinct one was so great... I would have imagined that the difference would have been proportionnal with the body weight, thus that the fang weight would have been 25% greater (100-110 grams), but 140 grams...

Perhaps this big difference is a consequence of a harder life, the predation would be harder during the Pleistocene era than in the extant day. Perhaps too, the cave lion was used to hunting some more powerful preys, more able to fight and resist. Hence the necessity to have some noticeably heavier fangs.

Do the claws follow the same tendancy ?

Those 15 cm upper fangs were most likely belonged to those alpha territorial overlords.

You can also see a lot of beta male cave lions with 11-12 cm upper fangs.

For the modern lion, a supersized overlord should have 13 cm upper fangs that weigh 100-110g each. Reply

@GrizzlyClaws :

About #2191: you told " For the modern lion, a supersized overlord should have 13 cm upper fangs that weigh 100-110g each. "

OK, that puts into perspective the difference between alpha male cave lion and alpha male extant lion. I didn't know that modern lion's upper fang could reach and even exceed 100 grams. With the 110 grams weight, we recognize the "traditionnal" 25% difference we are agreeing between extant and cave lions.

So in your four fangs set of 266 grams (see #2185) with the 3 - 2 - 2 - 3 formula, we deduce the upper fangs weigh 80 grams and the lower fangs 63 grams.

As concerns the cave male lion's upper fangs of 140 grams, we deduce the lower fangs weighing around 93 grams each, thus the four fangs set would be approximately 466-468 grams.

And as concerns the extant super male alpha lion with the upper fang weighing 100-110 grams, the four fangs set would reach 332-368 grams.

Very interesting. An alpha male extant lion is an apex predator, no contest. But what about an alpha male cave lion sharing its environment with large pride of grey wolves and hyenas, cave bears (and perhaps tigers too) ? Perhaps not the only one apex predator. Thus a harder life to suffer...

I will look at among your posts some other fangs and claws of extinct lions (cave and atrox). Just to notice the extreme weights. Same things as concerns extinct and extant tigers. Reply

Here is an old fang of South China tiger, and this one is perhaps one of the densest big cat fangs that I've ever seen.
