Hey guys! I'm new to the forum and have something neat to share that came from Hockley Valley Ontario. I found a descent sized piece of what I believe is fossiliferous limestone. This was in a clearing on my property near Hockley Village! I had posted it on mindat.org which some kind people had directed me here to help further identify the fossils in it and maybe learn more about this specimen. We deduced that it was likely limestone but with some hard silica in it as it was able to mark glass. The rocks dimensions are 17 × 12.5 × 4.3cm and it weighs roughly a pound (I don't have a precise scale). That last picture shows translucency within some of the fossils when lit. Pretty incredible could there perhaps be mineralization happening here? I can disclose any specific fossils' dimensions if required but the largest is 3.5cm long and also my favorite on the piece. It is the one with a one inch nail in its picture. I'm looking forward to learning more about this beauty!

Any IDs y’all can pick out on this rock? I think I see crinoid, but I’m extremely new to this and could use any and all help! Found in a creek on the Cumberland plateau in TN, SCOTT county. Thank you in advance!
