"The four field trips in this volume focus on sedimentology and paleontology in Texas. All the trips can directly trace their roots to the work of early geologic explorers"--Provided by publisher.

A Field Guide to Fossils of Texas is the only definitive guide that presents a collection of the state's most common fossils and also shows the most important, noteworthy, and unusual specimens.

The Late Cretaceous Pen, Aguja and Javelina Formations and Tertiary Black Peaks, Hannold Hill and Canoe Formations are exposed on and around the Pitcock Rosillos Mountain Ranch, adjacent to Big Bend National Park, Texas. The objectives of my project were to produce a geologic map of these sedimentary strata on and around the Rosillos Mountains laccolith and to collect fossil vertebrates from the units of interest. I worked on unmapped areas of the Pitcock Ranch and tested the validity of the geologic map of the park produced by Maxwell et al. (1967) where it falls on the ranch. Numerous differences were found between the Maxwell et al. (1967) map and my observations, while many features coincide. The geologic map produced is important because it includes previously unmapped areas and revisions to a previously constructed map of the area.

Through photos and narrative, some of Texas' most dedicated scientists show you actual specimens of dinosaur material found in Texas, as well as dinosaur exhibits found throughout the state.
