- Source: Marshalltown Formation
The Marshalltown Formation is a Mesozoic geologic formation. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
The famous Ellisdale Fossil Site, a konzentrat-lagerstätten which contains one of the most diverse Cretaceous vertebrate assemblages known from eastern North America (likely rapidly buried in a massive flood event), is an exposure of this formation.
The Marshalltown Formation stretches across southern New Jersey, and is largely composed of marine sediments deposited off the eastern shore of Appalachia, although the Ellisdale site represents a deltaic or estuarine environment, and thus has more of a terrestrial influence.
