Ordivician19 Posted June 2, 2022 Share Posted June 2, 2022 (edited) Hi! I’ve been working on opening some nodules from Mazon Creek, IL, and opened this one about an hour ago. I’ve been looking at pictures online of jellyfish and have seen some loosely defined like this nodule, though this is probably just a regular old concretion. What do you think? Thanks! P.S. In hindsight I realize that wetting this nodule down wasn’t particularly helpful lol Edited June 2, 2022 by Ordivician19 More photos were added Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted June 2, 2022 Share Posted June 2, 2022 I think it's fracture marks, but there are plenty of folk with more experience of the Mazon Creek than I, so let's see what they reckon. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
RCFossils Posted June 2, 2022 Share Posted June 2, 2022 Yea, this is an Essexella. The preservation is not great but it is not unusual to find them preserved this way. 2 1 Link to comment Share on other sites More sharing options...
