Saurian Teaser

I hope by the time you read this I am not being savaged by a cold. I had last week off work, which was very helpful in getting Dad's present finished. Naturally, having to that point avoided the deadly cold which had been slaying (well, inconveniencing) people in this locale since just before Christmas, I succumbed. Anyway, today's teaser is much less tantalising than the last one: dinosaurs!
