Fossilis, spalea and Atrox? Was the American lion a "lion"? The cave lions (P. spelaea/fossilis) and the American lion (P. atrox) were not modern lions (P. leo). However, they are most closely related to the modern lion (P. leo). On the other hand, these species are most distant from the tiger (P. tigris) and a bit less distant, but still distant, from the jaguar (P. onca).

Fossilis, spalea and Atrox? Was the American lion a "lion"? Interesting, thanks. So in this case probably the name of this thread is better to be changed otherwise many non-profesional readers could be confused that the word is about lions, while these were different animals. Same as once upon a time smilodon was called "saber-tooth tiger" but actually has nothing to do with the tigers. Probably: "Pleystocene Pantherinae cats" or something like this. So in genus Panthera are 2 clades: 1. tiger and irbis 2. lion, jaguar, leop, Panthera spelaea and Panthera atrox. But if jaguar is bit more distant to those cats than modern lion, than inside clade 2 probably should be created sub-clade of "lion-like" Pantherinae cats: leo, spelaea and atrox. If lion is really bit closer to those cats than the jaguar than this create some headache, this a bit contradict the theory that spelaea and atrox were not lions. I'm not sure does the science allow to create termin: "lion-like" Pantherianae cats, "lion-like" mean they were a lions....in same time they didn't belong to specie Panthera leo…. 
For the service of the average enthusiast it's better IMO to keep referring to them as lions (because that's what they're most related to), as simply calling them "cats" doesn't exactly help to clarify what exactly they were.

It is of course ok to speculate and observe, but there is still science community with professionals, who change classifications when they see, that there is enough information and justification to do so. I don´t think, that people here have enough competence to create new classifications even though there can be reasons to make good estimations about future. I would find it quite interesting if amateurs would start to make own realities ignoring what professionals are saying. Changing some classification for sure happens if and when there is enough information, which is agreed broadly in science community.

Probably you don't know that lion, jaguar and leopard are very closely related and create one group inside genus Panthera, while tiger and snow leopard are also closely related and create another group inside genus Panthera:  *This image is copyright of its original author Panthera fossilis/spelaea and Panthera Atrox are officially included in the firsts group. Before you insult somebody else first read some literature. Even wiki will be Ok for you if you want to make your first steps in this topic (see the Philogeny tree): https://en.wikipedia.org/wiki/Panthera About change of what "official" names you talk about? The only official name in biology is this in Latin letters, others are only nick names. For example in Canada Puma concolor is called "cougar", in USA - "mountain lion", in Europe - "puma", in Florida - "panther". That is not important, important is what is written in Latin letters. In same way somebody could call Panthera fossilis "cave lion", somebody in Argentina could call it "cave ostrich" or "cave elephant". The "official" name of the animal is in Latin. But the nick names of the animals should not confuse the readers. "Lions" are only the animals who belong to specie Panthera leo. Pahthera fossilis and P. Atrox didn't belong to P. leo so they were not "lions". Its easy like 2+2=4.

I know quite good situation with these animals and that those are studied all the time. For instance what comes to panthera atrox, there is research information (quite new one) saying, that it is closer to lion and tiger than jaguar, then again same time another one saying, that basically it is closer to lion and jaguar, than tiger. That is why I said, that it is better to wait and see (my opinion). It is interesting to see, what can be found out about this animal in future, but at least most research seem have one common feature, that it looks like to have had same origins as lion at some point and most research looks like to indicate, that lion is closest species or "sister species". For me it looked like a little bit jumping ahead of research at this point to start to think new names for well known american lion :) Who knows what next reports tell us. Maybe we have had after all some lion species there and only panthera leo survived to modern days... interesting subject of course.

 New article out on the new cub Spartak. https://siberiantimes.com/science/casestudy/news/ancient-cave-lions-had-spots-believe-scientists-after-analysing-starving-cub-spartak-preserved-in-permafrost/  *This image is copyright of its original author He appears to have faint spotting on his back, but it does not seem to be very extensive. Boris (who is identified as a bona fide cave lion by the author despite previous doubts that he may be a lynx) seems to be rather plain, and Uyan as we previously know had faint spots atop the head, not in a dissimilar place to Spartak I guess. The spotting on the cubs doesn't seem to be as prominent or extensive as in extant lion cubs, which in my mind raises the likelihood that the adults had very plain coats indeed, moreso than the faintly-spotted coats of today's lions. Just gorgeous.

These are completelly diferent species of animals, closelly related with lions just like the Longdang "tiger" Panthera zdanskyi is related with the true modern tiger Panthera tigris, but are not the same species or even subspecies. Panthera spelaea is not a hybrid, but a diferent crono-species related with Panthera fossilis, that evolved in Eurasia. The similarities between cave lion "spelaea" and the modern tiger are just primitivism inhered from Panthera fossilis. Even Panthera atrox still have some of thos characteristics, but that doesn't mean that these are "tigers" at all. (10-28-2018, 06:26 PM)Smilodon-Rex Wrote: That is a fan-made chart.
