Submitter notes: This crushed(see next photo entry for crushed side) example is to show what a blastoid in this condition might look like. It is 11.5 mm high by 9.8 mm wide at the widest. This was collected in 1991 from the Martin-Marietta spoil piles in Milan, MI where blastoids are far more rare then, for example, at Paulding, OH.
