Three skulls in three dimensions

October 21, 2020

Get your red-cyan glasses — you do have some, right? — and check out this glorious image. Best full-screen it, it’s worth seeing!

And here is the lame 2D version for those of you who have still not spent 99 lousy cents on a pair of 3D glasses:

What are we looking at here?

Well, the smaller skull at bottom left is my new badger, which we saw a couple of days ago. Since then it has dried out, and I was easily able to figure out which teeth belong where, and glue them in with a drop of wood glue. I’ll photograph it in more detail at some point, but for those of you who can’t wait, there’s always the TNF of my first badger skull.

On the right is, if I’m not mistaken, a sheep — specifically a ram, given the horns. I don’t actually remember this one’s origin story, but it’s been sitting on a box next to our oil tank for a couple of years, with the flesh bits slowly decaying off and the bone cleaning itself up the way nature intended. A couple of days ago I cleaned it up a bit with my trusty toothbrush to remove some bits of moss and lichen, then soaked it for a few hours in very dilute bleach. It’s dried out beautifully, and is very robust. It’s big, too.

Everything else you see belongs to a deer — I assume, based on the horn bases. This is another one recovered from the depths of time. Some years ago, I put it a big water-filled pan and left it outside and forgot about it. In that time, not only had all the meat rotted off the bones, but the water had clarified and everything in it had died, so it didn’t even smell particularly. When I took the bones out, they were a nasty brown colour and little soft, and I thought I was going to have to discard them all. But once they had dried out they seemed a little more robust — though still brown. Then I left them overnight in dilute bleach, and when they had dried from that, they were their present much more appealing whitish colour, so I think they’re going to be OK.

Most of the cranium is intact in a single piece, though some of the sutures are wobbly and will need stabilising with wood glue. The mandible is in two parts, but both seem in decent condition. Right at the bottom left of the photo is a shard of bone by the tip of the mandible: this is the left nasal, which flaked off, but should be repairable. Everything else is vertebrae: atlas right behind the skull, axis by the snout, C3 just above it, and damaged C4 just below the atlas.

When it’s been put together a bit more, I will post some better photos, and I’ll see if anyone can identify the species.
