When I was in Paris, Notre Dame Cathedral was a definite stop. I decided to go up in one of the towers. It is quite a wait to get up to the top but provides a great view of the city. When I was up in one of the towers I noticed quite a bit of fossiliferous rock. The statues of chimeras and gargoyles contain fossils.
This appears to be some sort of clam.
Lots of molds of gastropod shells.

I am not sure are these chimeras or gargoyles or something else. That one on the left looks like an elephant.
