Dinosaurs and other Prehistoric Animals of Texas provides a quick reference to the more common and interesting animals that lived within the State’s boundaries over the past few hundred million years. This colorful guide is organized as a trip through time, starting with trilobites and other early invertebrates, through dinosaurs, and ending with ice-age mammals.
Names, their meanings and discovery dates, and facts concerning each animal are provided. This pocket-sized guide features photographs of specimens, journal illustrations, and skeletal and life model reconstructions of the various animals included in the guide. Emphasis has been placed on the position of Texas through geologic time in order to provide the appropriate tie between animals from a particular time period and their environments.
The information presented ranges from basic to technical, and enthusiasts of all ages will enjoy using this guide.

David Trexler is a research scientist whose career has focused on dinosaurs and their environments. He and his family are known for major paleontological discoveries including Maiasaura peeblesorum. His current research focuses on comparisons between past and present climate and its effects on animal life.
David was born and raised in Montana. He spent his early years working in his family’s rock shop where he learned rock, mineral, and fossil identification. Growing up along the Rocky Mountain Front, Dave learned firsthand the interactions between geologic, climatic, and biologic processes in a largely undisturbed environment. This background sparked an interest that has continued throughout his career. He always enjoyed sharing his love of rocks and fossils, and in 1985 began teaching field programs for the general public. In 1990, he began teaching college level courses in field paleontology and geology. Dave received dual undergraduate degrees in Biology and Earth Sciences in Montana, and a graduate degree in Vertebrate Paleontology in Alberta, Canada.
A driving force throughout his career has been providing participation in scientific research for the general public. Dave has conducted research and training throughout western North America. He has served as the staff paleontologist for several museums and currently works for the Two Medicine Dinosaur Center in Montana. Dave’s research includes climate and climate change from a paleontological perspective. His work has identified long-term cycles that have a major impact on present day events. A portion of this work is explained in his book, “Becoming Dinosaurs: a Paleontologic Perspective on Climate Change Today.”
