icycatelf Posted October 31, 2015 Share Posted October 31, 2015 (edited) I found this on my usual walks yesterday. What caught my eye was the finger-like shape with what almost looks like pencil-drawn lines inside. Any ideas what it is? I couldn't get any good close-up pictures, but if you look closely, you can see what appear to me as thin calamite impressions, leading me to believe that these "drawn" lines might actually be the calamite's needle-like foliage (though I could be horribly wrong). Lines can be faintly be seen to the left of the finger-like shape, but I've circled the most-noticeable (to me, anyway) impression to the right here: Edited October 31, 2015 by icycatelf Casual surface-collector and Pokémon fan.

Ptychodus04 Posted October 31, 2015 Share Posted October 31, 2015 Could it be a cephalopod? Regards, Kris Global Paleo Services, LLC https://globalpaleoservices.com http://instagram.com/globalpaleoservices http://instagram.com/kris.howe Link to comment Share on other sites More sharing options...
icycatelf Posted October 31, 2015 Author Share Posted October 31, 2015 (edited) Could it be a cephalopod? I don't think so. The spacing varies too much, which I've been told is uncommon for cephalopods. Plus, the segments don't stick up like I would expect a cephalopod fossil to. Like I said, the lines look almost like they were just drawn on with a pencil. Edited October 31, 2015 by icycatelf Casual surface-collector and Pokémon fan.

howard_l Posted October 31, 2015 Share Posted October 31, 2015 This is from Pennsylvanian sandstone from the Breathitt Formation which is not a true marine unit. Cephalopods would be restricted to true marine units like the Magoffin bed of the Pennsylvanian of Eastern Kentucky. My opinion it is not a fossil.

Auspex Posted October 31, 2015 Share Posted October 31, 2015 The pattern appears to continue in a layer under the surface: I'll bet that, if you remove the top layer, the pattern will prove to be ripple marks.

Rockwood Posted October 31, 2015 Share Posted October 31, 2015 Annularia (Calamites' leaves) would be more delicate than this. Another thought might be that it represents a nonconformity. Link to comment Share on other sites More sharing options...

Cephalopods would be restricted to true marine units like the Magoffin bed of the Pennsylvanian of Eastern Kentucky. My opinion it is not a fossil. Breathitt Formation? Yeah, I strongly doubt that it's a fossil. Just posting for safe measure. The pattern appears to continue in a layer under the surface: ~.jpg I'll bet that, if you remove the top layer, the pattern will prove to be ripple marks. I noticed that, though I'm not sure if it's a continuation or just a coincidence that it's shaped that that. I have a feeling that I wouldn't do a good job at removing the layer, though. It would probably shatter into a billion pieces... ^^' Annularia (Calamites' leaves) would be more delicate than this. Another thought might be that it represents a nonconformity. I had a feeling it wasn't calamite foliage since nearly none of the pictures looked similar, though there were a few odd ones here and there that looked slightly like it. But yeah, I definitely agree that it could be a nonconformity (that's what crossed my mind when I first saw it, but I didn't know the right word for it).

Herb Posted November 1, 2015 Share Posted November 1, 2015 I'm with howard on this.
