Probably a stupid question-- do wolverines ever have visible sutures? Usually I go by how fused sutures are to tell age, but I have an 18 pound female wolverine... size (5.5") and perfect teeth would say that's a young one, but the only semi-visible suture on her is her nasals and the zygomatics: (and yes, the nasals are misaligned, leaving her with a crooked nose. She also has accessory infraorbital foramen on the left side, which is also a neat but fairly common pathology) So now I'm assuming she's a mature adult... but I've also noticed my other 2 wolverines have fused sutures, and one is definitely old. I have 2 more in the process of cleaning but they are both huge males, likely older, so I imagine they'll be fused as well. However, I have several otter skulls that are about the same, so I don't know if it's a mustelid thing, a wolverine thing, or if I just happen to have had the luck to get several mature adult specimens with great teeth of a few species.
