Probably his best known research today are comprehensive articles and papers about the Yellowstone Petrified Forest where he reported the presence of conglomerates from stream deposits, breccias from mudflows or landslides, volcanic tuff from the numerous volcanic events, and lava beds.Fritz, WJ (1980a) ''Depositional Environment of the Eocene Lamar River Formation in Yellowstone Nati ...

Geologist
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, earth science, or geophysics, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field research (field work) is an important component of geology, although many subdisciplines incorporate laboratory and digitalized work. Geologists can be classified in a larger group of scientists, called geoscientists. Geologists work in the energy and mining sectors searching for natural resources such as petroleum, natural gas, precious and base metals. They are also in the forefront of preventing and mitigating damage from natural hazards and disasters such as earthquakes, volcanoes, tsunamis and landslides. Their studies are used to warn the general public of the occurrence of these events. Geologists are also important contributors to climate ch ...

Paleobotanists
Paleobotany, which is also spelled as palaeobotany, is the branch of botany dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments (paleogeography), and the evolutionary history of plants, with a bearing upon the evolution of life in general. A synonym is paleophytology. It is a component of paleontology and paleobiology. The prefix ''palaeo-'' means "ancient, old", and is derived from the Greek adjective , . Paleobotany includes the study of terrestrial plant fossils, as well as the study of prehistoric marine photoautotrophs, such as photosynthetic algae, seaweeds or kelp. A closely related field is palynology, which is the study of fossilized and extant spores and pollen. Paleobotany is important in the reconstruction of ancient ecological systems and climate, known as paleoecology and paleoclimatology respectively; and is fundamental to the study of green plant developme ...

Specimen Ridge
Specimen Ridge, el. is an approximately ridge along the south rim of the Lamar Valley in Yellowstone National Park. The ridge separates the Lamar Valley from Mirror Plateau. The ridge is oriented northwest to southeast from the Tower Junction area to Amethyst Mountain. The ridge is known for its abundance of amethyst, opal and petrified wood. It was referred to as ''Specimen Mountain'' by local miners and was probably named by prospectors well before 1870. The south side of the ridge is traversed by the Specimen Ridge Trail between Tower Junction and Soda Butte Creek. The trail passes through the Petrified Forest and over the summit of Amethyst Mountain el. .Schneider, Bill (2003) ''Hiking Yellowstone National Park.'' Falcon Press, Guilford, Connecticut. 101 pp. (pp. 199–202) Geology Specimen Ridge consists of a geological formation known as the Lamar River Formation.

Amethyst Mountain
Amethyst Mountain, el. is the highest peak and central part of a northwest – southeast trending ridge that lies between the Lamar River to the northeast and Deep Creek to the southwest within Park County, Wyoming.

Dorfopterus
''Dorfopterus'' is a genus of eurypterid, a group of extinct aquatic arthropods. Only one fossil of the single and type species, ''D. angusticollis'', has been discovered in deposits of the Early Devonian period (Emsian stage) in the Beartooth Butte Formation in Wyoming, in the United States. The first half of the name of the genus honors the discoverer of this formation, Erling Dorf, while the second half consists in the Ancient Greek word πτερόν (''pteron''), meaning "wing". The species name ''angusticollis'' is composed by the Latin words '' angustus'' ("narrow") and '' collum'' ("neck"). The only known specimen of ''Dorfopterus'' consists of an incomplete uncrushed telson (the posteriormost division of the body), which was long, narrow, styliform and with a central carina ("keel"). It had a special ornamentation consisting of rib-like curved lines on each side of the telson with reticulated (net-like) patterns between them. This ornamentation was unique, and did not oc ...
