Brondonh Posted November 17, 2019 Share Posted November 17, 2019 Im trying to find if anyone could help with this fossil. Im to conserned about the animal because its just a lil piece, but if you do know thats helpful. My main consern is what is wrapped around it? It appears to be bone on inside but what is fossilized around it. Thank you I can take more pics. I can only load 2 Link to comment Share on other sites More sharing options...

Brondonh Posted November 17, 2019 Author Share Posted November 17, 2019 These are edited. It looks like a buffalo chicken wing lol. Idk Link to comment Share on other sites More sharing options...
Rockwood Posted November 17, 2019 Share Posted November 17, 2019 I don't think that is a bone. Maybe some sort of shell in a phosphate nodule ? Link to comment Share on other sites More sharing options...
sharkdoctor Posted November 18, 2019 Share Posted November 18, 2019 It looks like you have shark coprolite that has been reworked. Shapes of this sort are very common in marine lag beds that have reworked shark coprolites. The core that you are seeing is one of the inner spirals. the remaining "wrapped" bits are subsequent spirals. Due to reworking, some of the spiral layers have been broken or partially removed. 3 Link to comment Share on other sites More sharing options...
Brondonh Posted November 18, 2019 Author Share Posted November 18, 2019 Wow thanks. I didnt even think of it. Ive found spiral and log shaped ones, but after looking around on google I've been passing them by often. Not sure the value, but can make a great gag gift. If you dont mind Im attaching a couple more pics of whats inside. When i was looking around there were crocdillian corpolites that looked similar. Do you think they could be or certain they are shark? Link to comment Share on other sites More sharing options...

I'm not an expert, but I don't think Crocs have the spiral intestines that produce that aspect in their coprolites. 2 Link to comment Share on other sites More sharing options...

Right! Only non-teleost fishes (like sharks, rays, ceolacanths, lungfish, etc.) have spiral intestines. Oh... and apparently some eurypterids, but that's certainly not relevant here. 2 Link to comment Share on other sites More sharing options...

Croc coprolite does show some architecture, but it is not spiral.

I have refs that state that croc feces never have inclusions because of their extremely efficient digestion but I also know that first paper that shows modern croc feces with inclusions. 2 Link to comment Share on other sites More sharing options...
sharkdoctor Posted November 21, 2019 Share Posted November 21, 2019 Same here. As best I can tell, hair and feathers are common inclusions and don't break down in the croc gut the way bone and teeth do. 2 Link to comment Share on other sites More sharing options...

Do you think they could be or certain they are shark? Quite certain of the diagnosis on this. These actually can have value both to collectors and researchers. At the very least you could trade them for things you like. More importantly, if you collect enough, you will start to get a nice picture of the local copro-fauna. Also, as you get a collection going, you will likely run across some that have inclusions or bite marks. These are very valuable to researchers. If you decide to start picking them up, I'd be happy to give you feedback on what you are finding. 1 Link to comment Share on other sites More sharing options...

Brondonh Posted November 22, 2019 Author Share Posted November 22, 2019 Ok thanks. I pretty much got my eye on the ground looking around all the time, been fascinated with fossils since I was young. Growing up in Venice helped. Ive been back in Venice the past month or so helping family and getting my time in while I'm here. I will definitely keep on here and share what I find if it's significant or questionable. I've been noticing possible geodes at this place I've been working, but really haven't found anything great. Definitely find lil sharks teeth and random pieces of bones. Corpolites are now on my list. Link to comment Share on other sites More sharing options...
