Does The Fossil Record Of Non-Mammalian Synapsid Digits Show An Increasing "Mammal-Ness"?, Emily Anderson, Matthew A. Mclain

Proceedings of the International Conference on Creationism

Non-mammalian synapsids (NMS) are a group of extinct amniotes present in the Carboniferous-Cretaceous geologic systems. NMS are recognized by evolutionary scientists as transitional forms between reptile-like animals and mammals, and are thought to increase in mammal-like characteristics as they progress through the fossil record, especially among the six therapsid subtaxa. Given that Scripture is clear that God created many independent kinds of land animals (Genesis 1:20-25), we sought to investigate the currently accepted evidence which is used to support the claim that NMS are transitional forms. In this study we focused on the NMS hands and feet, which have been …

Testing The Order Of The Fossil Record: Preliminary Observations On Stratigraphic-Clade Congruence And Its Implications For Models Of Evolution And Creation, Kathryn Mcguire, Sophie Southerden, Katherine Beebe, Neal Doran, Matthew Mclain, Todd Charles Wood, Paul A. Garner

Proceedings of the International Conference on Creationism

As a key evidence for macroevolutionary change, the fossil record has been the focus of much study as creation scientists have attempted to interpret its patterns in light of the Flood. Despite this importance, only rarely has the order of the fossil record been scrutinized in any detail, by creationists or evolutionists. We therefore conducted the first large-scale study of the congruence of the fossil record with evolutionary predictions in thirty years.

Our method begins with published phylogenies for organisms found in the fossil record. The order of appearance for each taxon on the phylogeny is assigned a rank, then …

Impacts Of Tectonic Subsidence On Basin Depth And Delta Lobe Building, Tian Y. Dong, Jeffrey A. Nittrouer, Brandee Carlson, Brandon Mcelroy, Elena Il’Icheva, Maksim Pavlov, Hongbo Ma

School of Earth, Environmental, and Marine Sciences Faculty Publications and Presentations

Channel avulsions on river deltas are the primary means to distribute sediment and build land at the coastline. Many studies have detailed how avulsions generate delta lobes, whereby multiple lobes amalgamate to form a fan-shaped deposit. These studies often assume steady subsidence and uniform basin depth. In nature, however, lobe building is disrupted by variable subsidence, and progradation of lobes into basins with variable depth: conditions that are prevalent for tectonically active areas. Herein, we explore sediment dispersal and deposition patterns across scales using measurements of delta and basin morphology compiled from field surveys and remote sensing, collected over 150 …

Stratigraphy Of The Metamorphic Rocks Of Niğde Massif And New Evidence Of Triassic Rifting Of The Inner Tauride Ocean (Central Anatolia, Türkiye), Mustafa Kemal Özkan, Metin Beyazpi̇ri̇nç, Ali Ekber Akçay, Muhamed Çoban, Osman Candan, Osman Ersin Koralay, Meftun Kerem Sönmez, Halil Yusufoğlu

Bulletin of the Mineral Research and Exploration

Metamorphites of Niğde Massif, which form the basis of the study area covering the Niğde vicinity in Central Anatolia, are composed of Late Devonian Gümüşler, Carboniferous-early Permian Kaleboynu late Permian Kızıldağ formation and unconformable Triassic-Late Cretaceous cover units from bottom to the top, which are separated from each other with unconformities. The Triassic succession (Söğütlüdere formation) of phyllite-marble-schist alternations with common amphibolite levels is first distinguished in this study, unconformably overlies the Paleozoic succession. Thick homogeneous marbles of Jurassic-Cretaceous period, is defined by quartzite at the bottom representing the unconformity at the base, is defined as the Kırtepe formation. The …

The Geology Of El Paso, William Cornell, Diane Doser, Richard Langford, Joshua Villalobos, Jason Ricketts

Books & Monographs

The Geology of El Paso describes the history of El Paso, Texas and its surrounding region from the Precambrian formation of the continent to the modern use of geologic resources. This book is written in an easy to digest format, with definitions or links for specific geologic terms and references for further reading. It reviews the formation and evolution of local landmark features such as the Franklin Mountains, Cerro Cristo Rey, and the Sierra de Juarez. Fossils and stratigraphic units of the El Paso area are described as well as important geologic features. The book puts the events that shaped …
