The Hornerstown Formation is a latest Cretaceous to early Paleocene-aged geologic formation in New Jersey. It preserves a variety of fossil remains, including those of dinosaurs, and contains direct evidence of the mass mortality that occurred at the Cretaceous-Paleogene boundary.[2][3]

Outcrops of the Hornerstown Formation are known from sites such as Edelman Fossil Park.[4]
