Last week I gave you this specimen from the Dead Zoo to have a go at identifying:



It came from a cabinet of cave bones, but Nigel Monaghan (Keeper of the Dead Zoo) wasn’t convinced that this specimen was actually found in a cave.
Partly that’s because it’s a fairly fragile specimen with poorly fused sutures – these don’t usually stay connected in cave deposits, but also because it’s from a species that you wouldn’t expect to find in the kind of caves that the rest of these collections came from. So what is the species?
I don’t think this is a very difficult one since I’ve done very similar specimens before (regular visitors should have had an advantage), so I was looking for cryptic or entertaining answers – and I was not disappointed. Tony Irwin got a great clue in, with a pun that reflected the genus:
I think we need to focus (did I spell that right?) on the shape.
It is of course the skull of a seal in the genus Phoca – and the blunt shape of the anterior portion of the auditory bulla suggests to me that it’s a Harbour Seal Phoca vitulina Linnaeus, 1758 rather than the very similar Spotted Seal, which has a slightly more accute angle on the anterior auditory bulla.
So well done to everyone who figured it out! Now we just need to figure out how it either got into a cave or (possibly more likely) got put into the wrong cabinet.
We see sea lions and harbor seals hauled out on beaches of sea caves all around the Santa Barbara Channel Islands. It’s not too phar phetched a notion.
Seals are notorious for losing their way. https://www.discoverwildlife.com/news/young-seal-found-miles-inland-released-back-into-the-wild/
He got sealed up inside!
Changes in sea level in the recent past could mean what is now a cave some way from the shore could have been adjacent to it.
In the process I at least learned that the bulbous lump of chewing gum is the auditory bull, or hearing bit. Took awhile to realise the eye socket was further forward than I first thought. I will try harder next Friday.
