There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

I have not seen such a piece mentioned in any 21st century paper yet and it seems to be important. Would anyone happen to know the source of the photograph of the mandible?

When searching the internet, I found these photographs. There was no additional information, but the photographs suggests the exacavation happened a long time ago. A zoologist or biologist must have written an article at some time. 

If I would be interested in details, I would read a number of articles about tiger evolution. I remember a recent Chinese article. In the references, I found a bit more about Japan tigers. Unfortunately, I lost the notes I made when the house was renovated.

I remember two things. One was they disappeared before the Toba eruption. Two was they were smaller than their neighbours in mainland Asia.


Is possible that they were the Amur tigers who suffered the insular dwarfism like the modern Sunda tigers?
Captive Amur tigers usually have big inner gap in bodysize, the most possible reason is because of the unstable ecosystem of North-East Asia that damaged the Amur tigers diversity in their lineages over the past history. Fortunately, some excellent lineages can be reserved by captivity, which can be growing larger than other. We cannot sure how huge the Amur tigers in prehistoric period, but we can image that some of them have  huge sizes  are closely related to their lineages.


I do believe that the Japanese tigers were derived as an offshoot of the Amur tiger lineage, albeit exposed to the insular dwarfism since the islandization of Japan.

The same instance happened to the Sumatran tigers, they used to be huge when the Sunda Shelf was connected to the Mainland Asia, but they became what they are now after the insular dwarfism.
