Nugget 0 Report post Posted February 18 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. Share this post Link to post Share on other sites
Fossildude19 10,382 Report post Posted February 18 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. Share this post Link to post Share on other sites
digit 3,489 Report post Posted February 18 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. -Ken Share this post Link to post Share on other sites

Aurelius 405 Report post Posted February 18 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. Share this post Link to post Share on other sites
Ludwigia 4,318 Report post Posted February 18 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. Share this post Link to post Share on other sites
