Great find @Pckts one day I had briefly seen that first photo on top but just by scrolling down with no details and by the size I could've sworn it was a male haha, she is massive, very impressive shoulders I can only imagine how big a male Mountain Lion in this same environment can look. north america is definitely the land of big Puma concolor.

North America doesn't have all the big cougars. It's like this, the size of the puma tends to increase away from the equator (which crosses northern South America) and towards the poles, so the biggest cougars would be found in Canada, the U.S.A., and South America south of the Amazon River, like the Patagonian region region shared by Argentina and Chile: https://www.msn.com/en-ae/news/middleeast/travel-ban-after-two-coronavirus-deaths-in-middle-east/ar-BB10dW0I?ocid=spartanntp, https://books.google.com/books?id=sSr8AAAAQBAJ&pg=PA12&dq=biggest+cougar&hl=en&sa=X&ved=0ahUKEwjRhcmGtZbbAhUDShQKHbu-BjwQ6AEIKjAB#v=onepage&q=biggest%20cougar&f=false

Over the years, I saw a number of documentaries on pumas in Canada, Chili, the USA (Florida, Texas and Oregon) and Patagonia. The largest pumas I saw were from Patagonia. In one documentary, researchers measured a female and three nearly full-grown cubs in an elevated region. The adult female was the longest I saw by a margin. 

A few weeks ago, I saw 'Wild Patagonia' (BBC). It has 3 parts. In the last episode, a biologist (or ranger) was briefly interviewed. When the BBC-crew asked him about problems, he said they had recently seen a 'huge' male puma. The advice was to stay away from him. Based on what I saw, I'd say he, regarding his size, hadn't exaggerated. The male was different from pumas in other regions. Apart from the colour (quite pale), he was much more robust than all other male pumas I had seen. The skull also seemed different (relatively larger).

In 'The puma - Mysterious American cat' (S.P. Young and E.A. Goldman, 1946), one can find reliable information about the size of pumas in different regions. Three females shot near Santa Cruz (Argentina) well over a century ago were 6.10 (208,28 cm.), 7.6 (228,60 cm.) and 7.8 (233,698 cm.) in total length, whereas a male shot near lake Argentina was 8.1 (246,38 cm.). My guess is they were measured 'over curves', but Goldman (pp. 191-192) offers no specifics on the method used.      

Skull measurements are more reliable. The tables in the book mentioned above (pp. 269-276), although based on a limited number of specimens (referring to skulls from the southern part of Argentina in particular), suggest there's little to choose between Patagonian pumas (Felis concolor pearsoni) and Colorado pumas (Felis concolor hippolestes). In length and width, skulls of pumas shot in British Columbia, Oregon and Colorado roughly compared to those of pumas shot near Rio Coy (Argentina), but the dentition in the skulls of pearsoni was heavier. The longest skull (237 mm. in greatest total length) was from a male shot near Meeker, Colorado. He was 227 pounds (102,96 kg.). Two other males also shot in the vicinity of Meeker were 164 (74,39 kg.) and 160 (72,57 kg.) pounds. 

Skulls of adult females only very seldom reach 200 mm. in greatest total length. The only 2 slightly exceeding that mark were from Meeker, Colorado and Coy Inlet, Argentina (pp. 273-276). The dentition in the skulls of pearsoni, again, is heavier. 

Skulls of pumas shot in the northern part of the USA and Canada are more rounded and a few mm. wider than skulls of pumas shot in the southern part of Argentina, whereas the rostrum often is a bit longer and wider in Patagonian skulls. In Patagonian skulls, the zygomata gradually converge towards the rostrum. In skulls from pumas shot in the northern part of the USA, in contrast, the angle between the rostrum and the zygomata is more acute. For this reason, skulls from pumas shot in the southern part of Argentina seem closer to skulls of lions and tigers, whereas skulls from pumas shot in the northern part of the USA seem closer to those of small cats (more rounded).

Wait a minute, does this mean that pumas can bite through each others' skulls, therefore that the jaguar isn't the only cat that can kill by biting through the skull?
