Ossicle Posted January 30, 2022 Share Posted January 30, 2022 I will do these over a few posts. The site is Jurassic Oxford Clay, Peterborough Member, c.163 ma at Yaxley in Cambridgeshire. Any help would be greatly appreciated! The scale is in mm. The first I thought was Genicularia Vertebralis, but it looks a bit different from the others I've found, and has three distinct lines at the bottom of an unusually straight column.

Ossicle Posted January 30, 2022 Author Share Posted January 30, 2022 The second I think could be an echinoid spine, because of the raised bumps. Link to comment Share on other sites More sharing options...
Ossicle Posted January 30, 2022 Author Share Posted January 30, 2022 The third I had two thoughts over - either crinoid related, or worm related. Link to comment Share on other sites More sharing options...
Ossicle Posted January 30, 2022 Author Share Posted January 30, 2022 And the last I have no clue, but it is bumpy. Link to comment Share on other sites More sharing options...
Ludwigia Posted January 31, 2022 Share Posted January 31, 2022 I think you're pretty well spot on with your ids, but the photos are unfortunately somewhat hazy. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Myrmica Posted January 31, 2022 Share Posted January 31, 2022 I agree with the echnoid spines, and I agree that the third photo shows tube worm tubes. Nice finds. 1 Link to comment Share on other sites More sharing options...
