We directly link iridium (Ir) anomalies in New Jersey to the mass extinction of marine plankton marking the Cretaceous-Paleogene (K-Pg) boundary. We confirm previous reports of an Ir anomaly 20 cm below the extinction of Cretaceous macrofauna (the

Rare Earth Element (REE) signatures have been used to test whether mosasaur bones in a basal Hornerstown Formation bonebed (the Main Fossiliferous Layer, or MFL) in New Jersey were reworked from the underlying Maastrichtian beds or deposited synchron

Discoveries at the Ellisdale Site (Campanian, Marshalltown Formation) in New Jersey add significantly to knowledge of vertebrate microfaunas east of the Cretaceous Interior Seaway. Lizard and amphibian remains from Ellisdale appear congeneric with ta
