JBkansas Posted May 22, 2022 Share Posted May 22, 2022 (edited) Found some interesting fossils with my wife and boys yesterday. 1. Guessing these are gastropod shells (all replaced with crystals) 2. I think these may be crinoid stalk fragments 3. Millions of sub millimeter round fossils (and brachiopod) Wife: I found a rock with the wavy sea fossil (bryozoan) and petrified wood. Me: that doesn't make sense, oh, it's concrete. I guess Kansas has so many fossils we use them as filler 4. Not sure what this is and didn't have a ruler handy Edited May 22, 2022 by JBkansas 2 Link to comment Share on other sites More sharing options...
Pseudogygites Posted September 28, 2022 Share Posted September 28, 2022 The fossils in picture #2 are definitely crinoid stems! The last photo is also almost certainly a segment of trilobite in cross-section. I think the group of "millions of sub millimetre fossils" is just the texture of the rock, but if you look closer they could be ostracod if they show any unique patterning or symmetry.

I posted it in it's own thread and the most likely seemed to be a gastropod (and it has similar silification and matrix to the gastropods in the first specimen). Trilos in our neck of the woods are small and very uncommon. 1 Link to comment Share on other sites More sharing options...
Opabinia Blues Posted September 28, 2022 Share Posted September 28, 2022 (edited) Picture 1: Gastropod cross sections Picture 2: Crinoid stems Picture 3: Oolitic limestone with a brachiopod Picture 4: A bryozoan in the upper left side of the image. Maybe a crinoid stem but it's hard to tell from the image. Picture 5: I like the suggestion of a trilobite cross section, but I'm not sure.

DPS Ammonite Posted September 28, 2022 Share Posted September 28, 2022 Looks like some repetition of photos on another post. The last one marked as number 4 but actually 5 is a cross section of a bellerophontid gastropod. http://www.thefossilforum.com/index.php?/topic/123737-wife-wants-to-know-if-anyone-can-id-her-fossil/&tab=comments#comment-1349881 1 My goal is to leave no stone or fossil unturned.
