I have to assume you've heard of him. I couldn't get that link to work. 1 Link to comment Share on other sites More sharing options...

Haha, I was thinking of saying (other than Ralph) in my previous reply, but didn't. So most of the nj ammonite knowledge you have is from examining MAPS's ammos? Would you say Horace G Richards is at least a decent source? “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...

Ralph is still alive, at least. Link to comment Share on other sites More sharing options...
non-remanié Posted October 24, 2018 Share Posted October 24, 2018 8 hours ago, Carl said: Here's what I see. Sorry: haven't read the other posts yet. The first 3 are ammonite chamber steinkerns. The one on the left of the first shot is probably Placenticeras, as is the one on the right. The "croissant" in the middle is Menuites. Nice find. The "cartilage" definitely does not look like chondrichthyan cartilage. Might be a mollusk steinkern of some kind. I agree with the 2 possible Xiphactinus teeth Can't tell what the "pathologic tooth or claw" is. Not at all likely to be a claw but possibly a fish tooth fragment The 6 teeth I would ID as Enchodus, Enchodus, croc, croc, croc, Pachyrhizodus "Scute" - nope. Just a rock "Plesiosaur tooth chunk" may just be a bone fragment - very hard to tell The mammal teeth are most likely modern - I'm seeing deer and rodent Hybodont cephalic hook rather than plesiosaur tooth Agree completely except can't tell about the "cartilage" . just need more pics. And I think it's a pathologic shark tooth blade 1 ---Wie Wasser schleift den Stein, wir steigen und fallen--- Link to comment Share on other sites More sharing options...
non-remanié Posted October 24, 2018 Share Posted October 24, 2018 Also not sure on the coprolite. Need more pics but I'm leaning towards concretion 1 ---Wie Wasser schleift den Stein, wir steigen und fallen--- Link to comment Share on other sites More sharing options...

Coprolite? @non-remanié I don't see how the first item could be a tooth of any sort. The second may be a concretion, but I'd say there's a chance the spiral has been abraded. “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...
non-remanié Posted October 25, 2018 Share Posted October 25, 2018 Joseph, that's not what I meant. I was referring to 3 different items. I meant that the tooth/claw was a pathological and damaged shark tooth blade. Its definitely still a bit unclear but that's my impression of it. I am very doubtful of the coprolite but its a slight possibility. If it is a coprolite it seems like a very unusual style of preservation for NJ as well. The side we can see well in one picture is too irregular. It may be a deformed burrow infill or other trace. 1 ---Wie Wasser schleift den Stein, wir steigen und fallen--- Link to comment Share on other sites More sharing options...
