Inferring Stratigraphic Position of Fossil Vertebrates from the Niobrara Chalk of western Kansas--Fig. 2

Fig. 2. Correlation of stratigraphic columns of localities in western Gove County, Kansas. Black bands indicate bentonites, seams, and in a few instances a change in lithology; white indicates chalk. Localities are numbered across the top and arranged in order from west to east. The unnumbered column at right is the composite stratigraphic column from Hattin (1982). Hattin's marker units are identified by the numbers at right, and Russell's (1929) marker unit H is also indicated. The relative vertical position of different stratigraphic columns in the figure is not significant. The arrow by Locality 72 indicates the change from gray to yellow chalk.
