This one is going to go down as one of my favorite finds in my fossil-collecting lifetime! I found this incredible, gigantic, articulated Archimedes in a road cut in Southwestern Kentucky in 1997. We found many delicate “corkscrew” stalks, brachiopods, and blastoids in the same area, but upon walking a little farther down the road I came across some oolitic limestone where this buddy had cleaved off and was lying on the ground in the brush beside it. That section of oolitic limestone was massive and not easy to chunk off, but there were a few other, smaller Archimedes in that also. You can see part of another one in the chunk with the larger one below.
