Typical calcareous claystone of Unit IV with organic matter and phosphatic stringers, fish debris, and fecal pellets (interval 207-1260A-46R-6, 48–69 cm). C. Limestone layers made up of cemented foraminifer sands interbedded with the organic-rich claystones from the lower portion of Unit IV (interval 207-1260A-48R-4, 47–67 cm).
