Cranial Morphology, Taxonomy, and Systematics of Pachycephalosaurids (Dinosauria, Ornithischia)
DownloadSpring 2022
Pachycephalosauridae (pachcycephalosaurids) were small to medium sized bipedal ornithischians, known solely from the Late Cretaceous of North America and Asia. These dinosaurs are characterised by thick, often domed frontals and parietals (frontoparietal dome), which are thought to have been used...

Ceratopsidae is a group of non-avian dinosaurs known for their distinctive cranial ornamentation and horns. This ornamentation has become the focal point of ceratopsid research and therefore has led to a state of affairs in ceratopsid palaeontology in which taxa are diagnosed on the basis of...

The human bony pelvis is important in many anthropological studies of archaeological populations and of human evolution as it balances two important human characteristics: upright walking and the birthing of large-brained infants. While it has been thought that the female pelvis is selectively...

A full understanding of the evolution of novel forms requires inference about their origins through the study of variation in extant taxa and clues from the fossil record. However, the origins of morphological diversity in many groups are obscured by the scarcity of transitional fossils or...

Leafrollers moths are one of the most ecologically and economically important groups of herbivorous insects. These Lepidoptera are an ideal model for exploring the drivers that modulate the processes of diversification over time. This thesis analyzes the evolution of Choristoneura Lederer, a well...

Osteology, Taxonomy, Phylogeny, and Body Shape Changes of Eocene Catostomid and Problematic Catostomid Fishes
DownloadFall 2016
Extant catostomid fishes occupy diverse aquatic ecosystems and niches in North America (NA). Less than 3% of catostomid taxonomic richness, or two species, are found outside of NA in Asia. Such adjunct and unbalanced distribution pattern has been established since the late Oligocene, when...

Bare-bones Paleontology: An Examination of the Systematic Methods Used in Vertebrate Paleontology and their Congruence with Avian Ichnotaxonomy
DownloadSpring 2016
Data used in the systematic paleontology of extinct vertebrates is limited to what can be collected from detailed comparisons of preserved anatomy. This restricts vertebrate paleontologists to those characters preserved on osteological specimens. Furthermore, parataxonomies such as ichnotaxonomy...

Mosasauridae is a lineage of extinct marine squamates that inhabited the world’s oceans during the Late Cretaceous (100-66 Ma). The name Mosasaurus was given to the first described specimen, which was a fossil discovered in Maastricht, the Netherlands, during the 1770s. Naturalists of the time...

Donovan, S.K., Jones, B., Harper, D.A.T.
The first fossil echinoids are recorded from the Cayman Islands. A regular echinoid, Arbacia? sp., the spatangoids Brissus sp. cf. B. oblongus Wright and Schizaster sp. cf. S. americanus (Clark), and the clypeasteroid Clypeaster sp. are from the Middle Miocene Cayman Formation. Test fragments of...
