Gruesome find (P2210004)
No dental records for seals.
Not a nice sight, and not a nice smell, but... interesting. The whole carcass had an appearance of wax, melting into the ground. Some detail of internal structure was evident, though I'm not a biologist so I wasn't able to identify much of it.
This is from very close-up with an ultra wide-angle lens, which has only added distortion to the confusion of what's what.
