bericson 0 Posted March 19, 2020 I found this in a stream in central Missouri, USA. Not sure what it is... in the base it appears that a crinoid existed in it and that this may have been some sort of cap or stem from a crinoid- however I can't find any pictures of anything like this. Any help would be appreciated! Share this post Link to post Share on other sites
