Dblackston Posted June 24, 2022 Share Posted June 24, 2022 (edited) Hello all. We were recently on 4-H trip to Greenwood County Kansas and stopped at a roadcut in the Kanwaka Shale. We have several questions, the first one is below. We found this crinoid stem with an encrusting Bryazoa on it. I believe this is Fistulipora but would like a more positive ID. Any help is appreciated Edited June 25, 2022 by Dblackston Link to comment Share on other sites More sharing options...

Missourian Posted June 26, 2022 Share Posted June 26, 2022 Re: the first specimen... the little hoods on the apertures indicate Fistulipora. Additionally, there appears to be tiny encrusting forams on the crinoid stem (red arrows): Not 100% sure on this, though. An example of these: 1 Context is critical.

Dblackston Posted June 26, 2022 Author Share Posted June 26, 2022 I had to look up what a Foram was. Interesting! Thank you for confirming the ID. I need to find some place that shows better the difference between the bryazoa. Specifically rhombipora and tabulipora. I haven't found anything online or in my guidebook that shows the difference well and the pictures I have found they look quite similar. Link to comment Share on other sites More sharing options...
X-fish Posted June 29, 2022 Share Posted June 29, 2022 The gastropod is Leptotygma it's one of the less common gastropods at that location. Nice find! Link to comment Share on other sites More sharing options...

X-Fish, I looked it up and it sure does look like that. It was one of the first finds of the day, it was perched right on top of the shale between two washes. It was like it's only monument to itself. Link to comment Share on other sites More sharing options...
cngodles Posted February 4, 2023 Share Posted February 4, 2023 The shell is too thick and the suture are too shallow for Leptoptygma. It is a good candidate for Strobeus paludinaeformis. 1 Fossils of Parks Township - Research | Catalog | How-to Make High-Contrast Photos Link to comment Share on other sites More sharing options...
