Reducing and understanding petrified wood theft at Petrified Forest National Park
… facing natural resource managers. The theft of petrified wood from Petrified Forest National Park is one type of depreciative behavior. Despite numerous anti-theft interventions, approximately 12 tons of wood disappear from the park each year. The focus of this study was to design, implement, …

Identification of Fossil Wood from the Specimen Creek Area of the Gallatin Petrified Forest, Yellowstone National Park, Montana
<p>The petrified fossil forests in the Specimen Creek area of Gallatin Petrified Forest contain spectacular petrified tree stumps, trunks and logs in horizontal and vertical positions. These fossils forests are embedded in early middle Eocene volcaniclastic rocks and piled in sequential layers.</p> …

Eolian Landscape History and Prehistoric Dune Farming in Petrified Forest National Park: A Geoarchaeological Approach to Understanding the Long-Term Use of a Marginal Landscape
… interaction in the eolian landscape in Petrified Forest National Park, Northeast Arizona. The Petrified Forest National Park is located along the southern end of an extensive sand sheet. This landscape was inhabited by Ancestral Pueblo people from at least A.D. 200–1400, and contains …

Understanding petrified wood theft from a moral reasoning perspective
… of this study was to estimate the extent of petrified wood theft at two popular petrified wood sites at Petrified Forest National Park and to describe the nature of the thieves in terms of their level of moral reasoning. A model of noncompliant behavior was developed that incorporated the …

Quantifying variation in teeth of Late Triassic vertebrates: implications for identification, palaeoecology, and biostratigraphy
… locality called the 'Green Layer' near the Petrified Forest National Park, Arizona, USA. Chondrichthyan (shark) teeth can be useful for biostratigraphy, but differences in tooth shape throughout the mouth can make disentangling species from one another difficult. Additionally, specimens are …

Rise of present-day tetrapods in the paleotropics of Late Triassic equatorial Pangaea: new insights from microvertebrate data
… the Thunderstorm Ridge site (PFV 456) in Petrified Forest National Park, Arizona, U.S.A, to fill gaps in the evolutionary record of specific groups (e.g., lissamphibians and lepidosaurs), as well as the vertebrate paleocommunity record of Triassic equatorial Pangaea. My first chapter …

Integrating morphological data from fossil and living species and the early evolution of ray-finned fishes (Actinopterygii)
… the Late Triassic Thunderstorm Ridge locality in Petrified Forest National Park, Arizona, USA. Placing this new animal into the context of an exceptionally preserved assemblage of fishes provides critical perspective on the early evolutionary history of freshwater fish communities, which host ~44% …
