In response to Paraknit's question... it's a dinosaur skull.
One of two, actually, that sit on the lower shelf facing each other. They came from a part work magazine that came out a few months ago, called Build a Dinosaur or some such. With each issue you got one part of your eventual dinosaur, the first part being the upper section of the skull. Like all these magazines the first one cost a paltry 99p or something, has the most exciting looking part and it's only after your kids have pestered you into buying the first three or four parts that you realise there's another ninety-six issues to go and they now cost £4.95 per issue. No, I have never succumbed to buying any of these rip-off items. But Hubby thought this section of the skull would make a great bit of war games scenery so he bought two. And there they sit. To the best of my knowledge they've never seen a game yet and I have no idea why they live on my spinning equipment shelves but they do look good and they're funny, so they can stay.
Yes I am a bit odd at times. And your point is.....?
