The summary of Petters (1976) represents current ideas of the Cretaceous stratigraphy of New Jersey. Baird's (1967) discussion is consistent with Petters's view that the Hornerstown Formation is regarded as partly Cretaceous and partly Tertiary. Some authors have used the term New Egypt Formation instead of Navesink in more southerly outcrops. Cretaceous birds have been recovered from three geographically distinct localities in New Jersey (Figure 2). With the exception of _Laornis_, all of the specimens described by Marsh (1870, 1872) came from Upper Freehold Township, Monmouth County, in the area including the settlements of Hornerstown, Arneytown, and Cream Ridge. The Meirs family operated a number of pits in this area and it is no longer possible to ascertain the exact provenance of specimens labelled only as being from Hornerstown. These could have come either from the basal Hornerstown Formation or the underlying Navesink Formation, both of which are Maastrichtian in age. Baird (1967:261) ascertained that the holotype of _Palaeotringa vetus_, from “friable green marl near Arneytown” was from the lower (i.e., Cretaceous) part of the Hornerstown Formation. The holotypes of _Telmatornis priscus_ and _T. affinis_, from the Cream Ridge Marl Company pits, on the other hand, are from the Navesink Formation. A more recently collected specimen from this area is the proximal end of an ulna (NJSM 11900) collected by Gerard R. Case from “marl piles near junction of Rtes. 537 and 539 in Upper Freehold Twp., Monmouth County, near Hornerstown.” This definitely came from the Hornerstown Formation but it cannot be said whether from the Cretaceous or Paleocene sediments included therein. [Illustration: Figure 2.--Localities in southern New Jersey of the main fossiliferous deposits that have yielded Cretaceous birds. (The bold line demarcates the inner and outer coastal plain physiographic provinces; B = Birmingham; H = Hornerstown; S = Sewell.)] The second general locality is near Birmingham, Burlington County, where the type of _Laornis edvardsianus_ was obtained from “greensand of the upper, Cretaceous marl bed ... in the pits of the Pemberton Marl Company” (Marsh, 1870:208). There is nothing to be added to Baird's (1967) conclusion that this specimen is latest Cretaceous in age.
