ABSTRACT Outcrops of Late Cretaceous Gulf Series strata (Woodbine, Eagle Ford, and Austin) in the Dallas area expose middle Cenomanian to the early Campanian (96 to ˜ 83 Ma) rocks, which are well known in the subsurface of the oil-rich East Texas Basin. Together with the underlying Comanche Series and overlying younger Gulf Series, this set of strata provides a record of the last 50 million years of the Cretaceous. Although both marine and terrestrial vertebrates are known in this interval, the Late Cretaceous record is primarily marine. On this field trip, sites are visited that have yielded sharks, bony fish, turtles, dinosaurs, crocodiles, pterosaurs, mammals, long- and short-necked plesiosaurs, and a classic record of mosasaur evolution.

Abstract The 1975 SEPM Research Symposium was organized around the topical considerations of Beach and Nearshore Sedimentation – Physical and Biological. The intent was to cover the topic from the generation of processes through the mechanics of the processes, interaction of processes with sediment and culminating in distribution of sediments and structures across the environment in question. This volume, derived from that symposium, provides a wealth of data on the details on the generation, hydromechanics and sediment interaction of processes operating in beach and nearshore environments. The subject is treated in such a way as to be of considerable benefit to coastal engineers, sedimentologists and field geologists.
