Ammonite, but what kind and why?

[Jesamine]

Hi, I'm Jes and this is my first ID post, so hopefully the easiest. 

I know this is an Ammonite, but I don't know what kind. What features identify it as a certain species?

I found it in Charmouth, Dorset, UK in April 2023. It was amongst the debris from a cliff fall on the beach.

I believe it is Pyrite with some Calcite in the middle.

I think that might be Echioceras raricostatum.

Highly evolute, quite flat, ribs sticking out slightly at the venter, no keel, or a very weak one. 

Very nice specimen.

Cool. Thank you. I'll look into that.

Sorry, that should read Echioceras raricostatum.

That's okay. I figured it. Yes, I can see it looks very much like the examples on Google images now I have a name. Thank you.
