Inoceramus valve resting on top of a Placenticeras ammonite

A cool piece frozen in time from the day they were buried together. Also a decent size Inoceramus shell for the area and always fun to find an ammonite. This piece is from Boulder, Colorado.

So far away but it looks a lot like stuff we find over here (except we don't have Placenticeras... other ammonites yes).

Yes, always nice to find an association piece... We have a topic for such fossils but I can never remember what it's called so I can't find it for you right now!

looks like Placenticeras was fossilized with his duvet, cool find!

Do you go to prepare the Placenticeras?

 

I don't have the tools to prepare any piece more than just hitting it with a hammer. I was lucky enough for the Inoceramid valve to pop right off and then I realized there was an ammonite under it

A really nice lucky split, well done! Great display-piece as it is :default_clap2:

That is pretty neat! Ain't it nice when you get a special suprise fossil that you did not expect to be there at all? :) 

 

Thanks for sharing!

Yeah, I once found an Inoceramid valve like this in the Haslam formation that had a bunch of brachiopods stowed underneath... Makes me wonder if it represents a behavioural thing or if it's just a coincidence or some sort of preservation assisted by the shell.

I guess brachs could be deposited death-assemblage style into an Ino 'basin' by currents, if they weren't obviously attached to the Ino shell, but who knows?
