Two New Species and a Revised Phylogeny of the Ellimmichthyiformes (Teleostei: Clupeomorpha)
DownloadFall 2015
The Ellimmichthyiformes is an extinct order of clupeomorph fishes. This group includes fossil species from marine, estuarine, and freshwater sediments ranging in time from the Early Cretaceous to the Eocene. In spite of the long history of taxonomic studies on the Clupeomorpha, phylogenetic...

The Role of Acoustic Detail in the Production and Processing of Vowels in Spontaneous Speech
DownloadFall 2016
This dissertation examines the correlations between morphology and spontaneous speech production and perception. Specifically, this dissertation focuses on a subset of irregular English verbs and the production of vowel formants and the perception of vowel durations of those verbs. The...

Systematics of an Oligocene-Aged Fossil Snake Assemblage from the White River Formation, Wyoming
DownloadSpring 2014
Extinct snake taxa are primarily recognized from isolated vertebrae. A new specimen from the Oligocene of Wyoming provides a rare opportunity to examine four nearly complete and articulated fossil snakes. Informally assigned previously to the ‘erycine’ vertebral form taxa Ogmophis and...
