rawwardigger Posted November 8, 2019 Share Posted November 8, 2019 I stopped at several road cuts on both sides of the TN River in Decatur and Wayne Counties Monday (Nov. 4, 2019). Two more damaged Rhizophyllums without the lids, some really nice geodized Crinoid and Cystoid Calyx along with several geodized stem segments and a geodized horn coral. Cephalopod sections in situ, other Calyx pieces, etc. I'll try to get better pictures soon!!

Al Tahan Posted November 8, 2019 Share Posted November 8, 2019 I’d say that’s a successful trip! Love the crinoids Link to comment Share on other sites More sharing options...
Fossildude19 Posted November 8, 2019 Share Posted November 8, 2019 Neat finds, with unusual preservation (to me). Thanks for posting this.

For more information about that type of preservation, look up "silicified evaporite syndrome."

Monica Posted November 8, 2019 Share Posted November 8, 2019 Interesting stuff! The geodized echinoderms look very cool - congrats! Link to comment Share on other sites More sharing options...
Shamalama Posted November 8, 2019 Share Posted November 8, 2019 Those are indeed some good finds there Roger. Interesting to see the geodization of the lower paleozoic material. Normally I see it in the Carboniferous material. Edit: I just read some of the papers regarding the "silicified evaporite syndrome." that @Oxytropidoceras mentioned above. Fascinating to think that the growth of a mineral could shove rock out of the way. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers. When a roadcut presents itself, they tend to lurch and weave. To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...
rawwardigger Posted November 8, 2019 Author Share Posted November 8, 2019 (edited) Thanks for all the comments (I don't know how to thank each person). Hoping the rain will expose more for me and others to find and lower water levels will assist me during my boating adventures! Thanks to @Oxytropidoceras for posting the information regarding the "silicified evaporite syndrome." Have A Great Day and Keep on Rocking!!

Jeffrey P Posted November 8, 2019 Share Posted November 8, 2019 Great finds. Congratulations and thanks for sharing. Do you know what ages/formations those fossils are from? Link to comment Share on other sites More sharing options...
rawwardigger Posted November 8, 2019 Author Share Posted November 8, 2019 Thank You @Jeffrey P. Most of these formations are Silurian/Devonian in age. To the best of my knowledge the layer that I found the Rhizophyllums and Geodized Crinoid/Cystoid is Silurian - Brownsport Group. Link to comment Share on other sites More sharing options...
FossilNerd Posted November 9, 2019 Share Posted November 9, 2019 I love those curved crinoids!
