Largest collection of coprolites Largest collection of coprolites George Frandsen (USA) owns 1,277 coprolites, or fossilized faeces, as documented at the South Florida Museum in Bradenton, Florida, USA, on 1 Aug 2015. His prehistoric poo comes from 15 states in the USA and eight countries worldwide. George began finding the fossils on camping trips to Utah as a youngster. A prize piece is “Precious” (below right), his largest true-to-form coprolite, weighing in at 1.92 kg (4 lb 3.5 oz). It was found in South Carolina and dates from the Miocene epoch, 23.8–5.3 million years ago. It is naturally glossy, feels and smells like rock, and was produced by a huge crocodilian species around 6 m (20 ft) long. “Coprolite” comes from the Greek for “dung stone”.
