The Tar Heel Formation, also known as the Coachman Formation in its southern region, is a Late Cretaceous (early to middle Campanian-aged) geologic formation in North Carolina and South Carolina. It preserves fossils, including amber dating back to the Cretaceous period. A locality known as Phoebus Landing, has been dated to 78.5-77.1 Ma.^[1]

Likely deposited in estuarine and inshore marine conditions, it contains a high diversity of vertebrate remains. It has one of the most diverse dinosaur faunas known from the former landmass of Appalachia.^[2]
