Experimental Fish Taphonomy with a Comparison to Fossil Fishes Faculty Dissertations (2003)
The abundant fossil fish of the Fossil Butte Member (Green River Formation, southwestern Wyoming) have been an enigma because of the near absence of modern-lake analogues which contain fish remains. The purpose of this study ...
The Heavens and The Earth: Excursions in Earth and Space Science Faculty Books (2015)
The Heavens and the Earth is a groundbreaking new textbook designed for the undergraduate, non-science major. Thoroughly Biblical in approach and content, it is the only college-level textbook in Earth and space sciences that advocates ...

Preliminary Assessment of the Petrology of the Hopeman Sandstone (Permo-Triassic), Moray Firth Basin, Scotland Scottish Journal of Geology (2015)
The Hopeman Sandstone is a cross-bedded sandstone of Permo-Triassic age that crops out in coastal exposures in northeastern Scotland. Although the unit has traditionally been interpreted as an aeolian deposit, partly on the assumption of ...
Intraformational Parabolic Recumbent Folds in the Coconino Sandstone (Permian) and Two Other Formations in Sedona, Arizona (USA) Answers Research Journal (2015)
We report sedimentary structures that in all ways resemble parabolic recumbent folds (PRFs) in the cross-bedded portions of the Schnebly Hill Formation, the Coconino Sandstone and the Toroweap Formation (Arizona, USA). Field evidence suggests they ...
The Petrology of the Coconino Sandstone (Permian), Arizona, USA Answers Research Journal (2014)
The purpose of this paper is to give a description of the overall petrology of the Permian Coconino Sandstone that outcrops prominently in Arizona, including the Grand Canyon. The Coconino is often regarded as something ...
Sand Injectites at the Base of the Coconino Sandstone, Grand Canyon, Arizona Sedimentary Geology (2010)
In the Grand Canyon, large tabular and wedge shaped sand-filled cracks commonly occur at the base of the Coconino Sandstone, penetrating downward into the coarse siltstones of the Hermit Formation. All previous workers have casually ...
Difficulties with a Flood model for the Green River Formation Journal of Creation (2006)
Some problems, though not insurmountable, exist with a lake model for the origin of the Green River Formation (GRF). However, critical evaluation of Oard’s Flood model shows it simply is not supported by field observations. ...
The Green River Formation of the west-central United States: Flood or post-Flood? Journal of Creation (2006)
Many creationists believe the Genesis Flood was responsible for the bulk of sedimentary rocks and fossils. However, disagreements often arise in trying to determine where the Flood/post-Flood boundary should be placed in the stratigraphic record. ...
The Green River Formation: a large post-Flood lake system Journal of Creation (2006)
vidence from lithology, sedimentology, paleontology, ecology, taphonomy, geochemistry and structural geology suggests the Green River Formation (GRF) was a large lake system. Certain features—such as multiple horizons of exploded fish, disarticulated fish and stromatolites—suggest the ...
The geologic setting of the Green River Formation Journal of Creation (2006)
Further evidence is presented that the Green River Formation (GRF) was deposited after the Flood following the tectonic uplift of Psalm 104:8. A shift from continental-wide to regional sedimentation patterns within local basins makes this ...
Field study of purported hardgrounds of the Cincinnatian Journal of Creation (2004)
A number of samples conventionally believed to be indicators of hardgrounds are located in the Cincinnatian (Upper Ordovician) carbonates of the east-central USA. These consist of borings (especially Trypanites) in both fossil and limestone surfaces, ...
