Part II - State of New Jersey

AMMONOIDEA 117Range outside New Jersey--Alabama, Arkansas, Mississippi--zone of Exogyra ponderosa(Santonian, early Campanian). Western Iuterior of North America--Niobrara, Telegraph Creek, Eagle formations and equivalents (Coniaclanto early Campanian).Type.--In his first publication Morton gave no figures and did notstate any details about specimens. A year later he figured two specimensthat are presumably to be taken as eotypes, though no localitiesare assigned. As noted above, one of these survives and bears the numherANSP 19878.Baculitessp.Plate 68, Figures 5-7Ba_mlitcs ovata Ssy (part). Morton, 1828, Acad. Nat. Sci. Phila. Jour.,vol. 6, p. 89, pl. 5, fig. 5 (not fig. 6) ; 1830, idcm, p. 196, pl. 8, figs.6-7 (not fig. 8).Baeulites ovatus Say (part). Morton, 1830, Am. Jour. Sol., 1st ser., vol.17, p. 280; vol. 18, p. 249, pl. 1, figs. 6-7 (not fig. 8).Baeulites ovatles Say (part). Morton, ]834_ Synopsis, p. 42, pl. 1, figs.6-7 (not fig. 8).Remarks.--Several specimens illustrated by Morton as Baculitesovatus seem not to belong to the species. Tile specimen figured ill1928 as his plate 5, figure 5, shows numerous strong ribs on the flanksof the shell. The specimen figured first in 1830 as his plate 1, figures6 and 7, and refigured several times elsewhere, shows widely spaced,extraordinarily narrow ribs that extend entirely across the flank andrenter. This specimen is ascribed to St. Georges, Del., and would thereforebe from the hit. Laurel-Navesink unit. It is preserved as specimenANSP 19496-A.Baculitessp.Plate 68, Figures 8, 9Baenlites asper Morton. Whitfield, 1892, p. 278, Ill. 46, fgs. 10-11.Baculites asper Morton? Wellcr, 1907, p. 823, ph ]09, figs. 6-7.Remarks.--This fragment of a large shell, ascribed to the Navesinkmarl at Holmdel, is indeterminable, but it is definitely not B. asper.The large size, the coarse areuatc swellings, and the oval cross section,together with the relatively high horizon, distinguish it. It suggestssome of the larger species of the genus, such as B. n*_datus Stephenson(1941, Univ. Texas Publ. 4101, p. 405, pl. 79, figs. 5-10) or B. grandisHall and Meek (1856, Am. Acad. Arts Sci. Mem., n. ser., vo]. 5, p. 402,pls. 6-8). The specimen was reported by Whitfield as in the collectionat Rutgers College but is apparently not available now.NEW JERSEY GEOLOGICAL SURVEY
