The cretaceous birds of New Jersey

This revision presents fossil avian material from Late Cretaceous (Maastrichtian) marine deposits of New Jersey, incorporating newly collected specimens from the Inversand marl pits and reexamining century-old types. About eight genera and nine species are recognized, most assigned to a primitive charadriiform-like assemblage provisionally referred to the form family Graculavidae (including genera such as Graculavus, Telmatornis, Anatalavis, Laornis, and Palaeotringa). A new family, Tytthostonychidae, and the genus and species Tytthostonyx glauconiticus are proposed for a distinctive humerus possibly allied to procellariiform or pelecaniform birds. The fauna appears neognathous but cannot be placed in modern families.
