Choristothyris plicata from the Navesink Fm.

Choristothyris plicata is a common brachiopod found in the latest upper Cretaceous sediments (Maastrichtian stage) of the Navesink Formation in New Jersey. I have collected many specimens from the banks of Big Brook near Marlboro, Monmouth County, NJ.

A very good website for information about the geology of the NJ coastal plain as well as fossils that are found at Big brook is the website.
