Jens Johansen Posted May 21, 2017 Share Posted May 21, 2017 I found this piece of flint at the Beach last week. I'm not sure what it is - and just wondering it might be a fossil. If you have any idea what is it and how old it is, please let me know. :-) Link to comment Share on other sites More sharing options...
TqB Posted May 21, 2017 Share Posted May 21, 2017 What a great specimen! Maybe it's a section through an inoceramid shell, perhaps in the area of its dentition - a surprising number of odd flint fossils turn out to be this. (You would normally expect to see the vertical fibrous crystal structure though so it may be something else.) Hard to find the right figure but something like this old plate (from: http://oceansofkansas.com/Inoceramids.html ). 4 Tarquin Link to comment Share on other sites More sharing options...
Kosmoceras Posted May 21, 2017 Share Posted May 21, 2017 I agree with Tarquin on the ID. Its preserved in flint and this is Cretaceous aged. 1 Link to comment Share on other sites More sharing options...
JohnBrewer Posted May 21, 2017 Share Posted May 21, 2017 When I first saw the photo a graptolite sprang to mind. Im not often wrong 2 John Map of UK fossil sites Link to comment Share on other sites More sharing options...
Jens Johansen Posted May 22, 2017 Author Share Posted May 22, 2017 (edited) Thank you all for taking the time to reply to my questions ! - it's very much appreciated and helped me search and study both "inoceramid Shells" and "graptolites" :-) Still I'm not sure what it is. (was) :-) Since it's Brown-colored flint I was told it's aprox. 61-66 Ma (Paleocene Danian) ?? Graptolites was around ~ 500 Ma ?? Nevertheless, I agree it do look very much like Graptolite :-) Very interesting site (Fossilforum) Thanks for sharing your knowledge with me.

Jens Johansen Posted May 26, 2017 Author Share Posted May 26, 2017 A local Danish guy helped me identify the fossil. It's the small pincer claw on a lobster Astacidea > oncopareia sp. aprox. 65Ma. 2 Link to comment Share on other sites More sharing options...

jpc Posted May 27, 2017 Share Posted May 27, 2017 Weird lobster claw... I like it. Certainly not Inoceramid because they have a very distinctive crystal structure that this guy does not have. 1 Link to comment Share on other sites More sharing options...
TqB Posted May 27, 2017 Share Posted May 27, 2017 Great specimen, that's an amazingly lucky break for a piece of flint! I wasn't happy with inoceramid due to the lack of prismatic structure, as jpc says. Usually, when it looks like a claw in flint, it isn't . 1 Tarquin Link to comment Share on other sites More sharing options...

Euripterid pieces often appear to have settled into dimples on the surface. Any chance this represents a similar phenomenon on a more subtle scale ?
