Macraster echinoids+holaster, hemiaster

[Shaun-DFW Fossils]

I probably like echinoids more than some people do..I found these in Fort Worth formation, Grayson, and strangely one of them came from a creek at the woodbine/eagleford border in arlington, but I’m told it’s not likely to have originated from that formation. I have a crate full of little echinoids not shown here, these are my biggest ones. One of my best macrasters seems to have little spines stuck to the bottom. Maybe that’s something else?
