Kallidecthes richardsoni Marine Shrimp - Mazon Creek Fossil 03d2c319f27a57c561cccbcbb7bc93ff Garnet are formed by metamorphismMarine Estuarine Shrimp: Fossil shrimp were first reported from the Mazon Creek area around 1860, but prior to the opening of Pit 11 in the mid 1950s, the diversity was remarkably small.
