The Black Creek Group is a Late Cretaceous (early to middle Campanian)-aged geologic group in the southeastern United States, where it is known from the coastal plain of North Carolina and South Carolina. Deposited in brackish or nearshore marine conditions, it preserves fossils, including a diversity of dinosaurs and marine reptiles.[1]
It consists of the following geologic formations:[1]
- Tar Heel/Coachman Formation (oldest)
- Bladen Formation
- Donoho Creek Formation (youngest)
Paleofauna
- cf. Deinosuchus rugosus
- cf. Coelosaurus antiquus
- cf. Dryptosaurus sp.
- cf. Lophorhoton atopus
- Hypsibema crassicauda - "Caudal vertebrae, fragmentary humerus, fragmentary tibia, metatarsal II."[2]
- Leptoceratopsidae indet.[3]
- Dromaeosauridae indet.
