Interdisciplinary Studies Masters Degree In Anthropological & Science Based Education, Robert Porter

Electronic Theses, Projects, and Dissertations

The goal of this project is to develop anthropological and science-based curricula that will emphasize a place-based approach while actively engaging students in their education. I developed two curricula for elementary aged students in San Bernardino. The first curriculum was based anthropologically on the local history of indigenous groups and early San Bernardino history. The second was based on paleontology here in California with a focus on dinosaurs and fossils.

To improve and validate the curricula I sent the examples to educational experts and had them critique the lessons and information provided. Then I used their input to improve the …

Redescription And Phylogenetic Analysis Of The Materials Assigned To The Taxon "Captorhinikos" Chozaensis, Jason Paul Jung

Electronic Theses, Projects, and Dissertations

“Captorhinikos” chozaensis is a multiple-tooth-rowed captorhinid reptile from the Lower Permian Clear Fork Group, undivided formation. Upon re-examination of the materials associated with the species from both the Chicago Field Museum of Natural History, and the Smithsonian United States National Museum, I reaffirm their affinity and collective identity as a valid taxon. “Captorhinikos” chozaensis does not, however, belong with either of the two members of its genus, C. valensis or “C.” parvus, instead occupying its own branch on the phylogenetic tree of the Captorhinidae. This conclusion is based in strong results from a combined phylogenetic parsimony analysis combined with …

Digital Reconstruction Of A Ceratopsid Pes, Ken Conrad Noriega

Theses Digitization Project

A complete and fully articulated right pes of a centrosaurine ceratopsid from the Dinossaur Park Formation of Alberta, Canada provides important information regarding the structure and function of the pelvic limb in this group. A reconstructed centrosaurine foot with all data coming directly from actual specimens could be accurately modeled in three-dimensional morphospace and provide the basis of a digital atlas of the elements.

Comparative Osteohistology Of Hyperelongate Neural Spines In Basal Synapsids (Vertebrata, Amniota): Growth And Mechanical Considerations, Adam Keith Huttenlocker

Theses Digitization Project

Basal synapsids comprise one of the best represented groups of early tetrapods and demonstrate a classic example of a macroevolutionary transition. The basal synapsid fossil record is of significant interest to paleontolists because it presents an excellent opportunity for studying the evolution of vertebrate morphology. In the present study, neural spine osteohistology is further examined across a broad range of basal synapsid genera with hyperlongate neural spines. Due to the limited availability of specimens and the comparative approach required for destructive analysis, the present study is divided into two major comparative investigations: analysis of hyperlongate neural spine in (1) Spenacodontidae …

A Reinterpretation Of The Small Captorhinid Reptile Captorhinikos Parvus Olson As A New Genus, Reanalysis Of Its Cranial Anatomy, And A Phylogenetic Analysis Of The Basal Reptilian Family Captorhinidae, Gavan Mcbride Albright

Theses Digitization Project

The cranial anatomy of the basal captorhinid reptile Captorhinikos parvus (Reptilia, Captorhinidae), is reinterpreted here based on analysis of a group of new specimens recovered subsequent to its original diagnosis as well as further analysis of the original specimens utilized in E.C. Olson's original characterization of the species. Structural features inconsistent with the generic description suggest the redefinition of C. parvus as a new genus, Rhodotheratus parvus. Analyses of basal members and selected derived members support the characterization of Rhodotheratus as a distinct taxon.
