HuckMucus Posted June 5, 2022 Share Posted June 5, 2022 (edited) I've got a baculite that has those weird things "growing" all over it (or "clinging to it). Mine is not pointed like that, but my curiosity is about the stuff clinging to the surface. Edited June 5, 2022 by HuckMucus Link to comment Share on other sites More sharing options...

And I can see silica being the material that the surface is made of, but I'm talking about those "things" all over it (that give the unsmooth texture). Unless those things are called silicas. I've never heard that before. Edited June 8, 2022 by HuckMucus clarify Link to comment Share on other sites More sharing options...
Fossildude19 Posted June 8, 2022 Share Posted June 8, 2022 I see no evidence of Rugose (horn) coral here. No morphology present - no anatomy visible. Looks like an interestingly shaped piece of chert, to me. 3 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."

Plax Posted June 8, 2022 Share Posted June 8, 2022 (edited) Was thinking the filling of a pinna-like mollusk. Filling would include preserved burrows running along the inner edge and of course any other cavity inhabitants. Shell is gone. If this isn't oval in cross section I'm wrong. This is just a suggestion, not an ID. Edited June 8, 2022 by Plax spelling Link to comment Share on other sites More sharing options...

This is just a suggestion, not an ID. Jackson County looks to be mostly Pennsylvanian in age. The item itself looks to be more shaped like a wedge shaped type door stop, rather than oval.

Plax Posted June 8, 2022 Share Posted June 8, 2022 wikipedia says Pinna goes back to the carboniferous so guess my guess is not too outlandish. 1 Link to comment Share on other sites More sharing options...

Missourian Posted June 8, 2022 Share Posted June 8, 2022 It probably is limestone containing phylloid algae, which basically are blade-like seaweed that were biologically calcified before burial. The conical shape of your piece is suggestive, but may just be happenstance. Here is a similar specimen, with several stringers of algae, also from the KC metro: 1 Context is critical.

Phylloid algae are calcareous by definition. They are not soft algae that later became calcified during fossilization. See first page: https://www.kgs.ku.edu/Current/2005/sawin/sawinandwest.pdf West, R.S., and West, R.R., 2005, Paleoecology of the Permian (Wolfcampian) Phylloid Alga Calcipatera from an In Situ Occurrence in Kansas, U.S.A.; in, Current Research in Earth Sciences: Kansas Geological Survey, Bulletin 251, part 1. http://www.kgs.ku.edu/Current/2005/sawin/index.html (date on which you viewed the online article). My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere.
