This tiny echinoid: 6.21 mm by 4.31 mm is extremely large for the species. Most range between 2 and 4 millimeters. The measurements were taken while taking pictures with my digital microscope. They are an uncommon find by most collectors. Seeing them in situ is extremely difficult unless the sediments have been very well weathered. Most I have found are from matrix I collected. The last picture of the 2 is meant to show the size range of these. The smaller one measures 2.68 mm long by 1.74 mm wide; and I have a few even smaller.
