Additions to the Ammonite Fauna of the Upper Cretaceous Navesink Formation of New Jersey

Abstract

New fossil collections provide additional information about the late Campanian and Maas-trichtian ammonites from the Navesink Formation of New Jersey. Late Campanian ammonites include Pseudophyllites indra (Forbes, 1846), Nostoceras (N.) approximans (Conrad, 1855) (of which Nostoceras (N.) stantoni Hyatt, 1894, is a synonym), Nostoceras (N.) hyatti Ste-phenson, 1941, Nostoceras (N.) pauper (Whitfield, 1892), Didymoceras cf. D. draconis (Ste-phenson, 1941), Exiteloceras rude n. sp., Hoploscaphites pumilus (Stephenson, 1941), and Jeletzkytes cf. J. nodosus (Owen, 1852). Maastrichtian ammonites from the Navesink Formation include Pachydiscus (P.) neubergicus neubergicus (Hauer,

Scaphites of the “Nodosus Group” from the Upper Cretaceous (Campanian) of the Western Interior of North America

“…All of these forms suggest a correlation with the D. cheyennense Zone and, possibly, the lower part of the B. compressus Zone in the U.S. Western Interior. The Nostoceras (N.) hyatti Zone is present in the phosphatized fauna at the base of the Navesink Formation at Atlantic Highlands, New Jersey (Cobban, 1974;Kennedy and Cobban, 1993;Kennedy et al, 1992Kennedy et al, , 2000b Reeside, 1962: 126, 127, pl. 71, figs.…”

“…He grouped these forms together into the ''nodosus group'' and noted that they differ from other Scaphites ''chiefly in form, by having the involute part generally proportionally larger, and the deflected part shorter; also in having periphery of bodypart more or less flattened, with a row of nodes along each of its margins, and sometimes another near the umbilicus.'' Over the succeeding 150 years, the scaphites of the ''nodosus group'' have been variously assigned to Scaphites by Whitfield (1880), Gilbert (1896), Logan (1898Logan ( , 1899, Smith (1905), Weller (1907), Frech (1915), Diener (1916), Stephenson (1941), Donovan (1953), Jeletzky (1960,1962,1968,1970), Birkelund (1965Birkelund ( , 1966, and Atabekyan and Khakimov (1976); Hoploscaphites by Gill and Cobban (1966), Hirsch (1975), and Kauffman (1977); Acanthoscaphites by Nowak (1916), Reeside (1927a), Elias (1933), Coryell and Salmon (1934), Landes (1940), and Cobban and Reeside (1952); and, most recently, Jeletzkytes by Riccardi (1983), , Kennedy and Cobban (1993), Kennedy et al (2000b), Landman and Waage (1993), Landman and Cobban (2003), and Larson et al (1997). Not surprisingly, many of the generic diagnoses themselves have changed over time.…”

Nostoceras hyatti is a widely used zonal index for the uppermost Campanian in lower and middle latitudes (Gradstein et al 2012), with the original record from Texas (Stephenson 1941) and numerous ones from North America (Anderson 1958;Cobban and Kennedy 1993b;Kennedy and Cobban 1993c;Kennedy et al 2000a;Larson 2012) Summesberger et al 2007;Niebuhr et al 2011;Machalski 2012), the Levant (Lewy 1967;Kennedy and Lunn 2000), North Africa (Hennebert et al 2010), as far South has Southwest Africa (Howarth 1965). It is also present at Botellos.…”

The biogeography and ecology of the Cretaceous non-avian dinosaurs of Appalachia

“…The Maastrichtian Navesink Formation is mainly composed of glauconitic clays (e.g., Sugarman et al, 1995;Kennedy et al, 2000;Miller et al, 2004) and has preserved the best known non-avian dinosaur fauna from the Maastrichtian of Appalachia. This extensive fauna includes a diverse assemblage of theropods, including an ornithomimosaur and two possibly distinct species of tyrannosauroid, a nodosaurid, a basal hadrosaurid, and lambeosaurines.…”
