OK, these shouldnt be too hard. I have hunches, but not really strong on these types. First is from Belgrade mine, NC. Thinking alopias... These three are from Lee Creek. Not at all sure... Fairly certain these guys are alopias...

These little echinoids, referred to locally sometimes as "cheerios" because they average about the same size as one. They are a relatively common find in the basal sands of the early Oligocene River Bend Formation, often in association with Rebecapecten trentensis. This specimen is one of my smaller ones; 6.1 mm in diameter and is cleaner than most. Many of these have a calcite coating with black and white sand granules on them. In the last photo; the group shot, it is the one on the upper left. The smallest in the case. Reference: Kier, P.M.
