1. At the imposing front entrance of the 'Natricity Museum' Alec loses his nerve and says he doesn't want to go in and see the dinosaurs. We promise him that there are plenty of other things to see and that he needn't look at dinosaurs, and he is happy with that.
2. I stop startled at a megatherium skeleton posed with a tree trunk as if it is munching on some high foliage. I knew they were large (giant sloth, see) and elephant-sized, but I hadn't processed the idea of an elephant-sized sloth. While I am staring I lose Nick and Alec. I find a glyptodon skeleton and lose them even more while I am picturing an ice age swamp abounding with car-sized armadillos.
3. Pterodactyls fossilised in sheets of rock in a tangle of wings and limbs like insects on a windscreen.
