Skulls, Skeletons, Canines & Claws

[Panthera]

@GrizzlyClaws agree, thanks 
@tigerluver According to this map, it should in red circle, so it is 11500-10000 years old

-----------------------------------
This is another sharing about a P4 fossil of Felidae from a outcrop in the Northern of Yunnan province, south China. Actually geological layers and era is unknown, but other large mammalian fossils from the same site include panda and Gigantopithecus, so this tooth fossil from the Pleistocene.

I have two personal thoughts:


A. It is Tiger.
@tigerluver mention that the largest Amur skull be measured by him had a P4 of 34 mm and length of 380 mm. 
If this Yunnan P4 fossil of 36.5 mm is tiger, the skull probably exceed 380 mm (although different subspecies maybe has different transformation coefficient), right? Therefore, what I want to say is the Pleistocene tiger in south China is big, it body bigger(it is "randomly" discovered individual) than modern Amur tiger, the almost largest individual of the largest tiger subspecies.

By the way, some information :
<i>After the Toba eruption in Sumatra, about 78,000 years ago, the last population of Wanhsien tigers that survived in the north of Indochina-South of China, was the one that originated all the modern Mainland tiger populations. The location of this P4 fossil just near/in the north of Indochina-South of China.
<ii>There (Northern Yunnan) are 600 kilometres away from Wanhsien, Sichuan Province, site of Panthera tigris acutidens (Wanhsien tiger).   
------------------------

B. It is not tiger
I have also suspected that it may be Megantereon. The Genus had existed until early Pleistocene in southern China. For example, a new Megantereon species---Megantereon microta was found in Guangxi province, China (Wang et al., 2015; Guangxi province also in south China, adjacent to Yunnan province). The Megantereon microta P4 appearance is almost same with Yunnan P4 fossil in my personal feeling, but the length obviously smaller (29.2 mm; paper's measurement data) than Yunnan specimen(35.5 mm); width also obviously smaller(14.8 mm; paper's measurement data) than Yunnan specimen(17.9 mm).

Megantereon microta (Wang et al., 2015), length is 29.2 mm, width is 14.8 mm.

Finally, I always feel that the yellow frame area of this Yunnan specimen is shorter/different than general tiger.....
