I’ve stumbled across similar pieces of limestone throughout the years, but never have been able to figure out what they are. This piece of whatever it is is by far the largest and I honestly don’t have a clue as to what it is. This and similar finds only ever seem to have grooves or striations around the edges and nothing regular (at least to my perception) on the top or bottom which leads me to think they are probably of a geological origin, but I have never come across anything that matches these oddities... As stated in the tags I found this in a creek (near Auburn, Nebraska) which I know complicated things but other pieces of the same (or at least similar) material were from crushed up Oread limestone (Shawnee Group) from the Plattsmouth member which produces Carboniferous fossils. Any help would be appreciated! Curse the attachment size limit!
