Very prominently displayed. Most likely washed downstream from higher elevations, although this creek is unlikely to flood (location was only a mile from the source) 6- CHARACTERISTICS I believe, based on my research, that this is a specimen of Callixylon Newberryi, however I have my doubts do to its size in comparison to specimens I’ve seen on the internet, as well as it's location (ancient New York vs. Kentucky)- however there's a theory out there http://www.fallsoftheohio.org/Primitive_Plants.html that proposes this may be fossilized driftwood. My specimen is ~17” high x 7” wide x 3” deep and ~20LBS, other pictured specimens are much smaller – however the segmentation and overall characteristics are very similar. I was visiting this area with my Fiance’, who searched the area for “Indian Beads” (crinoids) as a young girl while on picnics. We found quite a few crinoids stems, but once I found one, I had my mind open for other fossils. I saw this specimen from 20 feet away, and it was very obviously different from the surrounding rock in the creekbed. Please see attached pictures – I’m looking for anyone who may be able to verify my research. Link to comment Share on other sites More sharing options...
BSMiner Posted October 17, 2016 Author Share Posted October 17, 2016 All questions will be answered as best I can - other pics can be supplied..... One end really looks like marrow with a central ring and radiant growth - no tree rings (but I'm no expert in ferns, which probably grow differently. I'm wondering if this is worth anything, outside of being a curio? I just think it's a neat find and want to know what it is. Link to comment Share on other sites More sharing options...
Raggedy Man Posted October 17, 2016 Share Posted October 17, 2016 Maybe, I can't really say. It does look like something though. It could be petrified wood or a mineral growth that dislocated from its cavity. I will say that all the info we need is state, county, time period and formation. The info you gave gives an exact spot. While I applaud your thoroughness and attention to detail, I would restrict information that gives the exact location as people will see this and eventually strip the site clean. I'm just looking out for you and your sites. Good sites are hard to come by. Thanks for your post and welcome to the forum. Best regards, Paul ...I'm back.

fossilcrazy Posted October 18, 2016 Share Posted October 18, 2016 BSMiner, It looks to be Callixylon Newberryi to me. New Albany Shale is known to have the fossil wood from this Protogymnosperm. Link to comment Share on other sites More sharing options...
