It looks like it was originally hollow which would make it similar to some other dasyclad algae. 1 Link to comment Share on other sites More sharing options...

minnbuckeye Posted February 5, 2021 Share Posted February 5, 2021 The last two photos make me question Recepticulitid. From my experience (minimal), the geometric pattern continues around to the back of the fossil. Mike 1 Link to comment Share on other sites More sharing options...
LabRatKing Posted February 5, 2021 Author Share Posted February 5, 2021 This specimen has been shellacked with something, so it may not be worth further prep. This is one of the reasons I was in the receptaculid line of thinking: https://louisvillefossils.blogspot.com/2015/11/receptaculites-subturbinatus-fossil.html 1 Link to comment Share on other sites More sharing options...
