Additional Information
Dromaeosaurs were therapod dinosaurs from the Late Cretaceous, around 67 million years ago. These theropods are from the family Dromaeosauridae, otherwise known as the feathered dinosaurs.
The Hell Creek Formation is a series of fresh and brackish-water clays, mudstones, and sandstones deposited during the Maastrichtian and Danian (respectively, the end of the Cretaceous period and the beginning of the Paleogene) by fluvial activity in fluctuating river channels and deltas and very occasional peaty swamp deposits along the low-lying eastern continental margin fronting the late Cretaceous Western Interior Seaway.
