Anomuran microcoprolites are preserved in the Late Cretaceous lowermost Navesink Formation in Monmouth County, New Jersey. These microcoprolites occur within lens to cigar shaped phosphatic clay masses that occasionally include fragments of anomuran appendages. Individual microcoprolites are pellet or rod shaped and morphologically similar in longitudinal and cross-section to fecal material excreted from the ventro-dorsal hindgut of modern anomurans. The association of these anomuran microcoprolites in situ with Orphiomorpha burrows and the decapod crustacean Protocallianassa provides a compelling association for the identity of their producer.
