This slab is a slice of Dinosaur Dung, called 'Coprolite' (coprolite comes from two Greek words that basically mean 'dung' and 'stone'). You can see by the photos that it has a number of fractures, so doubtful the buyer could get anything by a few small cabs of out this one; carefully polishing it as a display would probably be ok. But very neat piece unpolished as it is. It measures 4 1/4" x 2 1/4" x just over 6 mm thick, and weighs 81 grams or 2.8 ounces.
