CrustaceousBaki Posted April 17, 2023 Share Posted April 17, 2023 (edited) Earlier this week I had 2 concretions pop open that I weren’t too sure of what they were. Number one has the calcite desiccation cracks that are consistent with Achistrum sp. I guess the shape is what is kind of throwing me off, and the body seems to segmented, which reminded me of a millipede. Number 2 I cant really see any discernible features in it at all but if I had to guess a type of a polychaete worm? Anyway I’m gonna leave this to the experts lol. Any help is appreciated!

CrustaceousBaki Posted April 17, 2023 Author Share Posted April 17, 2023 (edited) I forgot this picture if that helps any (number 1) Edited April 17, 2023 by CrustaceousBaki Link to comment Share on other sites More sharing options...
connorp Posted April 17, 2023 Share Posted April 17, 2023 (edited) The first is Coprinoscolex. The gut pellets are diagnostic. The segmentation is due to shrinkage after death, they were not segmented in life. I don't see anything identifiable about the second.

Mark Kmiecik Posted April 20, 2023 Share Posted April 20, 2023 I agree. Not much detail in the second one, and the shape itself is not indicative of anything identifiable. Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
