Alex Mccabe Posted February 17, 2017 Share Posted February 17, 2017 Here I have the front, left, and right profile of a rock that I came across next to a creek in Elizabeth Town, Kentucky. Given that it has symmetrical featuress on both sides it appears to be a skull of some sort. I need help identifying what this is. I was unable to upload a picture from the bottom but in the back there is what looks like an area for the spine to attach to the "skull." Help would be much appreciated.

ynot Posted February 17, 2017 Share Posted February 17, 2017 Welcome to TFF! This is not a skull, it looks like a geodized crinoid calyx. Nice find! Tony 1 Darwin said: " Man sprang from monkeys."

Alex Mccabe Posted February 17, 2017 Author Share Posted February 17, 2017 Thats kind of what I was thinking because there is a crystal formation visible on the bottom. Thank you for you help! Link to comment Share on other sites More sharing options...
fifbrindacier Posted February 17, 2017 Share Posted February 17, 2017 Nice indeed, and welcome from France. 1 "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

Rockwood Posted February 17, 2017 Share Posted February 17, 2017 Seems possible but in my eye there is a gap left in the identification. Link to comment Share on other sites More sharing options...

abyssunder Posted February 17, 2017 Share Posted February 17, 2017 Try to compare with the specimens from THE FORMATION OF GEODES WITH REMARKS ON THE SILICIFICATION OF FOSSILS - Ray S. Bassler.pdf Explanation of Plate XXI. Figs. 1-3, and 8-11, are X 11/2, while the rest are natural size. All of the specimens were collected in the Lower Knobstone shales at Button Mold Knob, Kentucky. Figs. 1 and 2. A geode with a crinoid column as a basis. 3. A small geode with small fragments of the crinoid column still showing on its surface. 4. A larger example retaining little trace of crinoidal matter. 5. The interior of a specimen similar to fig. 3, lined with drusy quartz. 6. A geode similar to fig. 2, with the crinoidal calcite removed. 7. Another geode derived from a much fractured crinoid column. 8 to 11. Four small geodes showing their derivation by deposition of silica in crinoid columns. 12 and 13. Top and side views of two small geodes whose formation from crinoid columns is apparent from their five-sided outlines. 14. A mass of crinoidal fragments showing silica replacing the larger fractures. 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.
