Figure F5. Close-up photographs of characteristic lithologies of pelagic sediments in Unit III. A, B. Burrow mottled fabric containing traces typical of the Zoophycos trace fossil assemblage; (A) interval 207-1257A-16X-2, 95–108 cm; (B) interval 1257A-17X-1, 40–55 cm. C, D. Portions of the gravity flow deposit at the contact between Cretaceous and Tertiary sediments. Because clasts in this deposit contain Tertiary microfossils, the deposit is not related to events that occurred at the K/T boundary; (C) interval 207-1257B-12R-5, 15–27 cm; (D) interval 207-1257B-12R-5, 115–128 cm.
