A time-traveling field guide to the ancient version of Big Bend National Park. The sheer beauty of Big Bend National Park, along the shores of the Rio Grande in west Texas, never fails to astonish. Yet what lies beneath this natural treasure may be even more extraordinary than what meets the eye. Hidden in the rocks of Big Bend are the remains of giants: toothy sea lizards, enormous flying reptiles, and dinosaurs. Dinosaurs and Other Ancient Animals of Big Bend is a field guide to what once was. Inspired by the latest research, Cindi Sirois Collins and Asher Elbein imagine what it was like to walk among the plants and animals whose fossil remains tell the story of evolution and geological transformation in this singular landscape. We glimpse the drama of Big Bend’s rugged landscape in creation—the desert’s emergence from retreating oceans and volcanic eruptions. Immersive vignettes introduce dinosaurs, giant fish, and saber-toothed cats. And the history of discovery in the park proves a gripping tale, as paleontologists sifted major scientific insights from the soils, rocks, and riverbeds. Complete with vivid illustrations, this is a wholly original sensory and narrative experience that will deepen any reader’s knowledge and sense of wonder.

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.

The meat-eating dinosaurs, or Theropoda, include some of the fiercest predators that ever lived. Some of the group's members survive to this day—as birds. The theropod/bird connection has been explored in several recent works, but this book presents 17 papers on a variety of other topics. It is organized into three parts. Part I explores morphological details that are important for understanding theropod systematics. Part II focuses on specific regions of theropod anatomy and biomechanics. Part III examines various lines of evidence that reveal something about theropods as living creatures.
