A neat couple of black shale plates containing several fragmented specimens of this Early Jurassic echinoid. There are at least 8 notable specimens between the plates, some having associated spines, as well as some smaller test fragments and some loose spines. These urchins are quite small, with the largest ones only being around 1cm (.3937 inches) in diameter.
