Many years ago I was a child living in western Kentucky, outside of Paducah, in a suburb that backed up to a rural area. I was a rockhound. I had a big piece of cobble to use as a splitter and I split them open to see what was inside. My mother was horrified and kept taking my splitter but I'd find another. One rock that was clearly a fossil but I could not ID, lost when I carried it to jr high for a teacher to look at, had a star shape in the middle. Well not star, but like a skinny sea anemone, or a root system, lol. That cliff has the same pattern, thank you for posting it. The star on the left matches that long lost fossil
