For American "lion" Panthera atrox, the last one was the one from Christiansen & Harris (2009) with a weight of up to 351 kg, but there is one specimen that probably weighed more. No other new estimations appart from this.

For Machairodus and Amphimachairodus, the figures of over 400 kg seems to be very exagerated. The large skull of 415 is in fact less massive than that of a moder lions, so probably the real weight of this cats was less than those of the largest Pleistocene tigers and lions. Its bones are big, but not as massive as those of Smilodons.

For Smilodon populator, the last estimation came from Christiansen & Harris (2005) with weights of up to 400 kg for the largest ones. This is a short but very heavy and muscular cat.

The largest cat, with fossils available, is for the the Eurasian cave "lion" Panthera spealea fossilis. That skull of over 480 mm in length suggest a cat of about 400 kg. Certainly there are many fossils of the other lion-like cats and even none in the sample of giant  Panthera atrox in America is larger than it. However, the sample of Ngandong tigers is so small, that I do believe that the single femur found that already represent an especimen of c.370 kg is suggesting us that bigger specimens do existed.

What do you think about this new formula of 2016 which gave an output of 486 kg for the 480 mm femur?

BTW, @tigerluver has already possessed a piece of fossil which is larger than the largest Ngandong tiger. And it is believed to be a much younger close relative of the Wanhsien tiger, also its skull could reach over 480 mm as well.

This is like a bullshit.But American Lion is 600 kg

This article is 2017's article.I think this is accurate.

Could you tell me if you are trying to say, that in that study (link you shared) would be said, that American lions were 600 kg? 

Quote from that study: "These methods were chosen rather than using bone circumferences as it has been noted that P. atrox has relatively robust bones for their length (Sorkin 2008), and using the felid-specific equations from Anyonge (1993) lead to estimates of maximal P. atrox masses potentially exceeding 600 kg"

There isn´t said in this study, that result would be 600 kg, but that they ruled out method giving estimations that high as far as I understood. But maybe I misunderstood what you try to tell or something?

That didn´t answer to my question about American lion. Now you shared a different link about some finding in Russia. As far as I know, American lion (Panthera atrox) was living in different continent. So I guess, that you made just a mistake there earlier then?

This is for Cave Lion.For American Lionhttps://markozen.com/2018/04/11/the-north-american-cave-lion/

Well, good that it is clear, that American lions aren´t said to be 600 kg, so you made just a mistake, it happens to all of us time to time :)

Yes.Sometimes.And I think large American Lions can up to 600 kg(Or more) Reply
