The Occurrence Of An Abdominal Fauna In An Articulated Tapir (Tapirus Polkensis) Recovered From The Miocene Gray Fossil Site Northeast Tennessee., Shannon M. Mcconnell
The Occurrence Of An Abdominal Fauna In An Articulated Tapir (Tapirus Polkensis) Recovered From The Miocene Gray Fossil Site Northeast Tennessee., Shannon M. Mcconnell
Electronic Theses and Dissertations
The analysis of samples recovered from the abdominal area of an articulated tapir from the Late Miocene (4.5-7 million bp) Gray Fossil Site, revealed a rich palyno-fauna comprised of about 94% egg/oocyst-like structures and 6% pollen and other palynomorphs. In addition, a tight grouping of six hickory nuts (Carya) was recovered from the same area suggesting that the samples represent the abdominal contents. The analysis of a sample from immediately outside the tapir produced a sample with 98% pollen and less than 0.5% egg-like structures. The size, shape, and general morphology of egg-like structures were analyzed with light …
Salamanders Of The Mio-Pliocene Gray Fossil Site, Washington County, Tennessee., Grant Stanley Boardman
Salamanders Of The Mio-Pliocene Gray Fossil Site, Washington County, Tennessee., Grant Stanley Boardman
Electronic Theses and Dissertations
Screening efforts at the Gray Fossil Site, Washington County, Tennessee, have yielded a unique and diverse salamander fauna for the southern Appalachian Mio-Pliocene; including at least five taxa from three modern families (Ambystomatidae, Plethodontidae, and Salamandridae) supporting the woodland-pond interpretation of the site. All specimens represent the earliest record of their respective families in the Appalachian Mountains; with the Notophthalmus sp. vertebrae being the only Mio-Pliocene skeletal fossil known for the family Salamandridae in North America. Three types of plethodontid salamander are present, with one type representing the earliest known desmognathine. The desmognathine fossils lend credence to the 'Appalachian' origin …
Pleistocene Peccaries From Guy Wilson Cave, Sullivan County, Tennessee., April Season Nye
Pleistocene Peccaries From Guy Wilson Cave, Sullivan County, Tennessee., April Season Nye
Electronic Theses and Dissertations
Descriptive and taphonomic analyses of undescribed Pleistocene Tayassuidae from Guy Wilson Cave within the East Tennessee State University and McClung Museum collections revealed a MNI of 16 Platygonus compressus and 2 Mylohyus from left femora and isolated teeth, respectively. Linkage between upper dentition and species identification is suggested by comparing Mylohyus fossilis to M. nasutus from other Pleistocene-aged sites. Long-bone NISP and age profiles show a predominance of Platygonus adults. Tayassuidae upper canines, likely Platygonus, suggest sexual dimorphism. Long bones were analyzed for carnivore damage and utilization revealing light utilization similar to that caused by modern wolves. Long bone …
