Fossilised

This is Cherub's princess box:




And this is what is inside:




Together with:




And so on ... fossilised shark's teeth, a couple of ammonites and assorted other small fossils.

Cherub, inspired by an episode of Charlie and Lola, decided she liked fossils. I gave her a couple in the autumn and then added a small box of cheap fossils I bought on eBay to her Christmas stocking. It didn't have a list of contents, so we have been trying to identify them as best we can (my knowledge of fossils is close to zero!).

We think we have a belemnite:




A bit of dinosaur eggshell:




A gastropod:




And amber with an ant(?) and other debris inside:




Some were more of an identification challenge, and I'm not sure whether I have them right or not. This, I think, may be a toadstone (a fossilised fish tooth):




This one puzzles me. It may be a trilobite or crinoid fragment?




And this one. Fossilised bone, perhaps?




Any help with identifiction gratefully received!

Cherub has quite a good grasp of what fossils are, but her concept of time is still a little vague, as demonstrated by this conversation.

Star: How old are fossils?

Cherub: Very, very, very, very, very old.

Star: Older than Grandma?

Cherub (confidently): Oh, yes! .... (then more hesitantly) They are, aren't they?

I'm too tired tonight to have a go but it would be a good field trip... any decent museum should be able to identify 'em for you and then Cherub could see even more fossils. :)

Might be worth contacting them beforehand of course. We took one into the Natural History and had it done ad hoc but that was a decade ago.

your fish tooth is actually a vertebra and that trilobite that puzzels you is the moth plate of a stingray...
