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.
