Hi, can you take photos of the other sides of the stone ?

Nothing interesting there.

Around this specimen you see a few bryozoan and a partial crinoid facet.

All laid on the stone. An hash plate

 

N.B. I forgot: these are all decalcificied specimens.

Because this is the tipical aspect of all decalcified specimens (preserved as a limonite mould) coming from the Upper Ordovician of the mediterranean area (Portugal, Spain, Sardinia,...)

 

A recent topic, where it's possibile to see an example of this kind of preservation (it's a better quality specimen):
