A collection of Late Cretaceous decapod crustaceans from the New Jersey State Museum has led to revisions of previously known species. One new genus, Chondromaia, and four new species, Cenomanocarcinus robertsi, Chondromaia antiqua, Distefania lauginigeri, and Seorsus kauffmani are recognized, the latter from the Late Cretaceous of New Mexico. The fauna from the Late Cretaceous of New Jersey and Delaware is diverse, embracing species from Astacidea, Axiidea, Dromiacea, Homoloida, Dakoticancroida, Raninoida, and Majoidea. The occurrence of a majid crab in the Late Cretaceous marks the oldest occurrence of the family. Burrows containing chelae of Mesostylus mortoni and fecal pellets are some of the only known occurrences of the tracemaker found within its burrow.
