Taphonomic investigation into environmental effects on bone surface modifications.
… current project investigated the extent to which taphonomic processes such as short-term exposure to the Biostratinomic effects of weathering and diagenetic effects of the soil matrix may alter or obliterate evidence of cutmarks on bones. It examined factors that may contribute towards bone …

Taphonomic studies of fossil preservation in coarse-grained siliciclastic environments
… strata of the later Phanerozoic suggests that a taphonomic window facilitated this mode of fossil preservation. However, environmental and biological factors that promoted fossilization remain unclear. To experimentally identify mechanisms of preservation in siliciclastic sediments, cyanobacteria …

Examining the taphonomic challenges to the 3D digitisation of fragmented bone
… we need to understand the impacts that the taphonomic histories of such samples have on our ability to 3D record them. Understanding the relationship of these taphonomic histories and the surface and optical properties will promote informed choices about the suitability of recording …

Taphonomic and Faunal Parameters From Pleistocene Hominid Site Assemblages in China
… significance. Analytic techniques assessing taphonomic processes have not been readily applied, particularly in controlled cross-site comparisons. This paper uses faunal analytic techniques and taphonomic indicators to address issues of site comparability and early hominid site use …

The response of wetlands to sea level rise: Ecologic, paleoecologic, and taphonomic models
… power, however: ecologic, sedimentalogic, and taphonomic. No single microtaxonomic group is well preserved in all depositional environments. Foraminiferal assemblages delineate salt to brackish marsh environments, but are absent in fresh marsh sediments. Ostracodes and diatoms occur in all …

A taphonomic investigation of the agency of microfaunal accumulation at Elands Bay Cave
Up until the present, analyses of micromammal assemblages in South Africa have been based upon the premise that the agent responsible for the accumulation of these assemblages was the Barn owl. These micromammal assemblages were used to make extrapolations of past changes in vegetation and climate. …

Quantitative Ecological and Taphonomic Patterns in Late Cenozoic Mollusk-Dominated Marine Fossil Assemblages
Applications in paleontological research are far from being limited to taxonomic collection and identification. Nor is such research limited to working solely on fossil data. Actualistic paleontology is the study of modern or recent organisms and processes to better understand those of the past. …

Broken Bones and Cutmarks: Taphonomic Analyses and Implications for the Peopling of North America
… modification processes is critical. Through neotaphonomic research, this dissertation investigates patterns in butchering, carnivore gnawing, and human-induced breakage of large mammal remains. It quantifies cutmark and tooth mark frequencies, placement, metrics, morphology, and fracture …

A taphonomic study of seal remains from archaeological sites on the Western Cape coast
… analysis of seal remains. Most of the existing taphonomic indices cannot be applied to seals because of their unique physiology. Appropriate field observations and laboratory measurements are used to construct taphonomic indices that can be widely applied to seal bone assemblages. These include: …

Cold case files : palaeoforensic and taphonomic study of the Mamafura dicynodont from the end permian
… ecology of the Late Permian and it enhances our taphonomic understanding.

Ecological, Evolutionary, and Taphonomic Comparisons of Brachiopods and Bivalves at Multiple Spatial and Temporal Scales
The fossil record is the primary source of information on the history of life. As such, it is important to understand the limitations of this record. One critical area in which there is still much work to be done is in understanding how the fossil record, and our interpretation of it, may be …

Investigating Taphonomic Changes of Deposits and Modeling of the 2010 Earthquake and Tsunami in South-Central Chile
… but these deposits may have undergone taphonomic processes since initial deposition. Therefore, to determine how tsunami deposits change during burial and preservation and the potential limitations of using paleodeposits in modeling, I investigated the modern 2010 M<sub>w </sub>8.8 …

Mysteries of the Dead: A Taphonomic Analysis of the Skeletal Remains from the Peruvian Highland Sites of Marcahuamachuco and Cerro Amaru
This thesis examines the taphonomic changes on skeletal material recovered from the ancient sites of Marcahuamachuco and Cerro Amaru by the Huamachuco Archaeological Project in the 1980s. The remains were recovered from three different burial contexts: (1) Wall niches; (2) Underneath the Castillo; …

The fate of leaves in south eastern Australian terrestrial and aquatic environments: implications for taphonomic bias in the tertiary macrofossil record
An understanding of the taphonomic processes that form and possibly bias plant fossil assemblages is of central importance to understanding and interpreting some of the anomalies in the Australian Cenozoic plant fossil record. This study measured a variety of ecosystem processes in contiguous …

Late Pleistocene and Early Holocene Small Mammals in South West Britain: Environmental and Taphonomic Implications, and their role in Archaeological Research
This project examines small mammal faunas from cave sites in south-west England and south Wales. The aims are threefold:<br/>- To examine the rapid environmental changes taking place in the Late Pleistocene and early Holocene:<br/>- To understand the processes by which small mammal remains were …

Taphonomic comparison of Hypacrosaurus stebingeri (Hadrosauridae: Lambeosaurinae) bonebeds from the upper Campanian Oldman and Two Medicine formations of Alberta and Montana
… adult, respectively. These bonebeds show uniform taphonomic signatures throughout the assemblage, characterized by little to no weathering and abrasion, uniform style of fracturing, and rare tooth marks in the assemblages. All three bonebeds are interpreted as mass-mortality assemblages. …

Geochemical and Taphonomic Signatures of Freshwater Mussel Shells as Evidence of Mercury-Related Extirpations in the North Fork Holston River, Virginia
… with shell length (r=-0.3; p=0.2) or degree of taphonomic alteration (r=0.18; p=0.28). Analysis of 366 shells for taphonomic signatures indicated that shells are most heavily altered and fragmented directly downstream of Saltville. In contrast, upstream sites, inhabited by reproducing mussel …
