The Livingston Group is a geological formation in Montana whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.[1][2][3][4][5][6][7]

There are four units of the Livingston Group (from oldest to youngest): Cokedale Formation, Miner Creek Formation, Billman Creek Formation, and Hoppers Formation.[8]
