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 don't think so. The giant P. fossilis were never photographed and are in private collection, out of reach. The largest of the P. atrox skulls had canine alveole breadth of less than 40 mm.
In addition to my last post, I see in Christiansen and Harris (2009), P. atrox had proportionately wider canine than the other three big cats. It seems their style of measurement was different from Merriam and Stock, which I took my last post's data from.
