Got it from a friend. This actually should come in one piece and not separated like this. Probably someone split it up so that he/she could see the inside. Probably found in Papua, Indonesia. Please your ID. Thankyou.

This looks similar to Dactylioceras  sp. 

 

Can you put the ammonite down on the table, and take a picture of either side from directly above the fossil?

Also an edge shot from either side as well.

They do look very familiar. I have a piece of artwork from West Papua that includes two of the "negative" casts from the outside of this species of ammonite. I'm guessing the slaty matrix that these are found in separates quite easily and cleanly from these ammonites as you have both the positive as well as one of the negative casts. Would be nice if my piece of art actually had the ammonites instead of a matched set of negative molds.

 

Welcome to the forum.

 

 

Cheers.

Dactylioceras commune by the looks of it.

The ammonites are actually supposed to be split like that. The larger part is the fossil, the smaller is just the impression of where it lay in the sediment.

I don't think that there's any record of Dactylioceras from Papua. It looks at first glance to be a Cobbanites to me, but as Tim has already requested, side views of the keel would help.
