MyGodMagma Posted May 26, 2017 Share Posted May 26, 2017 Photo: top left Found in a small (10ft wide) woodland stream near the LA/MS border, (East Feliciana Parish, LA/Wilkinson County, MS) within the Citronelle Formation; formed during the Pliostene. While the Citronelle is oft noted to contain fewer saltwater fossils than expected for an ancient coastal plain, this stream has provided probably 95% of the marine fossils in my collection. As a longtime rockhounder but fresh off the boat newbie to fossil identification, I've struggled to find a match for this fossil. (The photo is one I had on hand, am preparing to paint and the fossil is buried in chaos right now.) Betting this ID likely is child's play for most of you, any light you can shine on this fossil would be so very much appreciated. -caroline "Excellent!" I cried. "Elementary," said he.

JohnBrewer Posted May 26, 2017 Share Posted May 26, 2017 Hi Caroline, welcome to the forum. Which item/s in you photo are you referring too? Can you include a ruler? John Map of UK fossil sites Link to comment Share on other sites More sharing options...
MyGodMagma Posted May 26, 2017 Author Share Posted May 26, 2017 It's the top left in the photo, the worm-like shape. I don't have access to that fossil right now, a good estimation of the total length of the little guy that left the imprint would be 45-60mm, slightly over 2" "Excellent!" I cried.

erose Posted May 26, 2017 Share Posted May 26, 2017 Appears to be a crinoid stem at first glance. Or at least the impression of one. 2 Link to comment Share on other sites More sharing options...

Oxytropidoceras Posted May 27, 2017 Share Posted May 27, 2017 I agree that it is definitely an external mold of a crinoid stem. Towards the right, this fossil also shows the internal mold of the lumen. Go see: A.

Thank you, everyone! Paul, these links are great, I appreciate you taking the time to include them. (When I joined Fossil Forum a few weeks ago, I nerd-geeked out a bit when I saw your account. I've been reading about your discovery of the Brushy Creek meteor crater here for the past decade. Talk about a nice catch, wow! "Excellent!" I cried. "Elementary," said he.
