Fig. 9 in Cephalopods from the Cretaceous/Tertiary Boundary Interval on the Atlantic Coastal Plain, with a Description of the Highest Ammonite Zones in North America. Part 1. Maryland and North Carolina

Fig. 9. Approximate correlation of the samples from Maryland with the Santee Coastal Reserve (SCR) core (Edwards et al., 1999). The horizontal arrows indicate sample locations in the SCR core. Because calcareous nannofossil Subzone CC25c is missing in the SCR core, Zone CC25 is shown as undifferentiated. The time scale is based on Berggren et al. (1995) as interpreted for the SCR core by Edwards et al. (1999).

Fig. 8 in Cephalopods from the Cretaceous/Tertiary Boundary Interval on the Atlantic Coastal Plain, with a Description of the Highest Ammonite Zones in North America. Part 1. Maryland and North Carolina

Fig. 8. Proposed ammonite zonation of the upper Maastrichtian on the Gulf and Atlantic Coastal Plain and the corresponding zones in the U.S. Western Interior. The base of each zone is defined by the lowest occurrence of the index ammonite. The ammonite zones are correlated with the established calcareous nannofossil zonation based on the biostratigraphic distribution of the dinoflagellates and nannofossils associated with the ammonites in Maryland and North Carolina. The D. minardi Zone has not yet been recognized in the Gulf Coastal Plain. Correlation with the ammonite zones in the Western Interior is based on the presence of Discoscaphites conradi and Isabelidinium cooksoniae.

Fig. 3 in Cephalopods from the Cretaceous/Tertiary Boundary Interval on the Atlantic Coastal Plain, with a Description of the Highest Ammonite Zones in North America. Part 1. Maryland and North Carolina

Fig. 3. Generalized stratigraphic sections of the Severn Formation at three sites in Maryland. The sections are arranged so that the ammonite assemblages (= zones) appear in ascending stratigraphic order from left to right. The Brightseat section is based on Owens et al. (1977: fig. 61), the Lloyd Creek section on Minard (1974: pl. 1; 1980) and Minard et al. (1977), and the Round Bay section on Minard (1980: pl. 1). The ammonites from Round Bay were probably collected from a site 2–3 km southwest of the type locality on the west side of the Severn River. According to Owens et al. (1977: fig. 61), this site is similar to the type locality. The stratigraphic position of the ammonites at Round Bay is shown with a question mark because the position is inferred based on the associated dinoflagellates with reference to the biostratigraphic zonation of the Severn Formation documented by Benson (1976) and Firth (1987).
