Rowboater Posted May 6, 2020 Share Posted May 6, 2020 Like most of what I find these days, this is small (the scalemarks are mm). A small cylinder with diagonal pattern of markings. Seems too solid for fossil cartilage or skin? Any ideas? Link to comment Share on other sites More sharing options...
Pemphix Posted May 6, 2020 Share Posted May 6, 2020 Crocodylian scute as it seems (very blurry fotos). With location, strata etc. probably more to say... Link to comment Share on other sites More sharing options...
Al Dente Posted May 6, 2020 Share Posted May 6, 2020 Maybe a segment of a bryozoan. Any chance we can see a cross section? 1 Link to comment Share on other sites More sharing options...
digit Posted May 6, 2020 Share Posted May 6, 2020 Agreed that the blurry photos make identification more difficult. From the description it is a cylinder and the two photos I'm assuming are showing both sides. In my experience crocodilian osteoderms tend to have a smooth side (bottom) and a very patterned side (top) and are never cylindrical. My thoughts leaned toward a very worn coral branch or more likely, as mentioned above, a worn section of a branching bryozoan showing the zooid chambers. Cheers. -Ken 2 Link to comment Share on other sites More sharing options...
Pemphix Posted May 6, 2020 Share Posted May 6, 2020 I agree - if it is a cylindrical piece it makes croc-scute unlikely.... Better pics and strata/location, pls... Link to comment Share on other sites More sharing options...

Rowboater Posted May 6, 2020 Author Share Posted May 6, 2020 @Pemphix, @Al Dente, @digit,@Tidgy's Dad, Wow, thanks everyone for the quick responses! I don't think it's a scute, it's a tiny, nicely patterned cylindrical "stone". It's inside is plugged, but looks like it could have been patterned , chambered on the inside as well? Both ends are rounded so hard to say. Al, what should the cross-section look like? I had recently found a "film" of bryozoans on several shells on the beach, thought they might be some type of fine coral, but people were helpful then also. Learned something today, thanks everyone! 2 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted May 6, 2020 Share Posted May 6, 2020 From springer.com And a cross section in some areas of one of my own Hirnantian Pachydictya. (Yours is not this genus). 3 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

Rowboater Posted May 8, 2020 Author Share Posted May 8, 2020 @Tidgy's Dad Thanks for the illustration! Looks very similar and with just a little imagination I can see something similar at the inside of the ends! 1 Link to comment Share on other sites More sharing options...
