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 can give you numbers now though. Marciszak et al. (2014) gave these two skulls:
San River: GSL=451 mm, CBL=402 mm, Canine alveole length=44 mm (Canine/GSL=0.0975)
Mauer: GSL=442 mm, CBL=393 mm, Canine alveole length=34 mm (Canine/GSL=0.0769)
So there's quite a bit of variation (going to toot my horn to repeat the problem with dentition and size estimation).
The Manchurian canine is about 37 mm in width as measured by Marciszak et al. (2014). So the skull would lie somewhere in the range of the aforementioned San River and Mauer skulls in all likelihood.
