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.
That is a good question. The fossils of the "tigers" in Alaska are few, which suggest that they were not very common. I guess that maybe they were just wandering specimens that never managed to establish a colony. The same happen with many other specimens in modern Siberia, recorded by Mazák (1983).
Barnett et al. (2009) stated that his study managed to prove that those tigers were in fact lions, based that he analyzed one of the bones labeled by Herrington (1987), however based in only one bone, if very difficult to state a fact in this form, and most of the Herrington's specimens are still without been studied with DNA.
