Help with ammonites and urchin ID

Recommended Posts

Hello all.

I just got back from an open day at a gem and mineral club. I picked up some fossils while I was there. Unfortunately, the mineral guys aren't so knowledgeable on fossils, so many were mislabelled and dont have information on them. I would love it if you guys could help me out.

 

Ammonite from Morocco

Two ammonites that come from Chile, I think...

And lastly an urchin that came with no information

The top one looks like a Triassic Ceratites spinosus from Germany. I don't know if they occur in Morocco. 

The last one looks like a chalk Conulus sp.

That last ammonite looks like an Amaltheus sp. The 2nd one may be an Arnioceras sp., but I'm not at all sure about that.

I suspected that it was from Europe. It looks a lot like some French ammonites that I've seen.

Ok for the Conulus. Maybe C. albogalerus from upper cretaceous of White Chalk
