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 remember that I even made a list for them, but I am going to post only those that I remember in this moment:
1. The sample size of the American specimens is too few, only 4.
2. All the specimens of Panthera atrox came from the sourthern limit of the ice sheet, which compromise the results and the origin of the bones itself, as it is well know that some fossils can be washed from areas far away from they original area.
3. Not a single specimen from Rancho La Brea or southern areas where used for Panthera atrox.
4. Only ONE jaguar was used in the sample for comparison, why they don't included more, specially an specimen from USA, which are many in they museums?
5. They claim that all the "tigers" from Beringia were "lions", but they only analyzed one of those specimens (FAM 69016 - dentary-ramus).
This are the most important issues about they study, that I remember right now.
