max pijpelink Posted March 9, 2021 Share Posted March 9, 2021 Hello, I found this piece 2 weeks ago on the beach of Breskens in Zeeland. I don’t know what it is and there were not several options. I get stuck with this piece of bone. I hope that someone know what it is! The sizes are in cm. Link to comment Share on other sites More sharing options...
val horn Posted March 10, 2021 Share Posted March 10, 2021 i dont know what you have. It does look like bone in atleast one of the photos. My fall back position is to ask for more photos, try to get rid of the shadows by being more directly overhead, which is sometimes easier said then done.

LabRatKing Posted March 10, 2021 Share Posted March 10, 2021 Looks like chiplodocus ( a joke term for "unidentifiable piece of fossil bone") to me, however it has a very well preserved bryozoan on it! Welcome to TFF! 1 Link to comment Share on other sites More sharing options...

The photos that you saw earlier were photos when it was found. Now it is more brown. I hope that the shadows are disappeared. Maybe a skull fragment because of the lines on the back?

Welcome to TFF! do you maybe know it is a fossil bryozoan or a test to see it is fossil? and maybe the species? Link to comment Share on other sites More sharing options...
val horn Posted March 10, 2021 Share Posted March 10, 2021 Maybe fish palate piece. That circle within circle where a tooth fell out Link to comment Share on other sites More sharing options...

That circle within circle where a tooth fell out The problem is that the size to big is as you ask me. And normal fish have many tooth by each other, this one is lonely.

val horn Posted March 10, 2021 Share Posted March 10, 2021 Your piece seems broken on the edge so it might not be one and done. Though it would be one monster fish. I don’t know what you have. What else has that circle within a circle pattern. I don’t know what you have but that rather unique structure should let someone recognize it Link to comment Share on other sites More sharing options...

If it is easily scratched with a fingernail it is likely an extant specimen. However, from the photos Im fairly certain that you have a fossil bryozoan on some fossil bone.

The planning was first to scrape it of if it doesn’t damage the bone but now it stays on. Is the species also known? Link to comment Share on other sites More sharing options...
Mahnmut Posted March 10, 2021 Share Posted March 10, 2021 Ahoi, I could imagine this to be part of a cetacean cervical vertebra, those are often reduced to flat discs, the bullseye pattern could be a remnant of a dens axis? All highly speculative due to the fragmentary preservation. I would keep the bryozoa no matter if they are fossil, they do not occlude any interesting part of the bone and are a beautiful piece of biodiversity.

max pijpelink Posted March 12, 2021 Author Share Posted March 12, 2021 The colour has be changed abnormal. So I think it is a subfossil from Holocene. Link to comment Share on other sites More sharing options...

Welcome to TFF! Wouldn't this more correctly be called Chunkothere, seeing as it's definitely mammalian (there are only a few places in the Netherlands that have yielded fossil reptile bone - most notably next to the German border, in the central east, and in the southern tip)? Anyway, unfortunately have no idea what this could be, other than, judging from conservation, likely Pleistocene and almost certainly mammalian... Have you tried asking on Paleontica? People there might be more knowledgable on their "local stuff" 1 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...
