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.

Since the formation of the modern tiger subspecies was occurred after the Toba eruption which was dated 75 kya.
I now start to believe that those antiquated tiger subspecies like Ngandong tiger and Wanhsien tiger were dated before the Toba eruption, while the modern tiger subspecies after.
That is correct, if we follow the genetic evidence in Luo et al. (2004), all the tigers after the Toba eruption are genetically decendents of the surviving population in the north of Indochina, so they belong to the present P. tigris crono-subspecies and that it splited in two subspecies at 12,000 year ago: mainland-P. t. tigris and Sunda-P. t. sondaica.
Could you make a size comparison between this big mandible and that of Panthera atrox? Just to intuitively visualize how big it really is.
