Big cat skull fossil in Late Pleistocene cave in Liaoning Province(map), northern China (Fu et al., 2010; Fig.7):
The text description said Canine crown length is 48 mm (base on scale bar I measurement, this number may said gum line); 
P3 length of 32.2 mm with width of 13.7 mm;
P4 length of 41.2 mm with width of 23.3 mm;
This article also said in fact tiger and lion are not easy to distinguish. However, because there is only tigers in China now, so this big cat skull fossil is classified as tiger temporarily, and need more studies in the future. 
About the age of this fauna, I read related articles, one consider this fauna in 50 ka (Dong et al., 2009), the other consider this fauna in 11.7-126 ka(Zhan et al., 2014; table2). However, there is a report consider the age earlier about middle Late Pleistocene about/over 200 ka(Wang et al., 2009).

If it is tiger really, the P4 is huge, bigger than the blue one. Is Canine's gum line length of 48 mm also big? How total length of the Canine may be? Reply
