Description/Abstract:: The purpose of this dissertation were threefold: (1) to develop a taphonomically-based facies (taphofacies) model for a classic, modern carbonate system, the south Florida shelf; (2) to compare and contrast the south Florida taphofacies model to the only other published modern carbonate taphofacies model, that of Parsons (1992) study of the northeastern Caribbean; (3) to compare and contrast a taphofacies model developed from the total mollusc assemblage (pooled sample approach) to models that only evaluate taphonomic changes within a single taxon as it occurs in different environments.

Description/Abstract:: Filtration theory was developed by engineers to model the removal of particulate matter from industrial gases. Recently, it has been used by biologists and paleo-biologists to model the capture of food particles by filter feeding organisms. The purpose of this study was to test paleosynecologic (biofacies-level) and paleoautecologic (species-level) models of crinoid distribution utilizing filtration theory. These models were tested by analyzing the crinoid faunas of three transgressive-regressive sequences from the Upper Pennsylvanian Lansing Group of midcontinent North America.

Description/Abstract:: The nature of taphonomic overprint affecting the fossil records of the regular echinoid Families Cidaridae, Diadematidae, Toxopneustidae and Echinometridae is investigated using a synthesis of actualistic and literature-derived data. The actualistic portion of this study focuses on the following extant members of the four families: Eucidaris tribuloides, Diadema antillarum, Tripneustes ventricosus and Echinometra lucunter. Population censuses of these animals in tropical reef and near-reef environments demonstrate that the distribution of macro- and microscopic skeletal material does not reflect the distribution of the living fauna. Field experiments with freshly-killed carcasses of Eucidaris, Diadema and Echinometra indicate that loss of all organic tissue occurs within six days after death, reducing these echinoids to essentially bleached carcasses.

Description/Abstract:: The taxonomy, phylogeny, biostratigraphy, functional morphology, and paleoecology of Middle and Upper Ordovician (Blackriveran-Richmondian) Monoplacophora and bellerophontacean Gastropoda of the Cincinnati Arch region are discussed. Six genera and 29 species of monoplacophorans, and 13 genera and 56 species of bellerophontaceans are evaluated. The study is centered around new U.S. Geological Survey silicified collections.
