Cave pollen taphonomy in Kurdish Iraq
This thesis aims to understand the mechanisms involved in pollen transport and deposition in cave environments and the influence of different factors on the composition of the pollen assemblage, with special reference to the problem of the Neanderthal ‘Flower burial’ at Shanidar Cave, Kurdish Iraq. …

Taphonomy of pigmentary colours in fossil insects
… approach is utilized to elucidate the taphonomy of pigmentary colours in fossil insects. Decay and tumbling experiments are combined to explore environmental, biological and compositional biases constraining the potential for fossilisation of cuticles in various extant taxa. In …

Dating Death: Forensic taphonomy and the postmortem interval
Determining the postmortem interval (PMI) remains one of the most important but challenging factors to establish in a suspicious death investigation. Unfortunately, as time passes current methods lose accuracy and only allow investigators to approximate how long ago death occurred. Bodies interred …

Chuaria, Vendotaenia, and the taphonomy of the Carbonaceous Compression
… preservational style for fossils, yet their taphonomy remains poorly understood. Previous studies focusing on the taphonomy of carbonaceous compressions have primarily looked at exceptionally preserved faunas in plane view. The precious nature of these fossils leaves destructive techniques of …

Burrows and bedding : site taphonomy and spatial archeaology at Tortoise cave
… of deposition. For this latter, the term 'Site Taphonomy' has been coined, to end the confusion that has existed concerning the meaning and correct application of the words 'Stratigraphy' and 'Stratification'. These terms should now be restricted to refer to the archaeological constructs alone, …

Taphonomy of Sediments: Bioturbation in the Triassic Moenkopi Formation in Southwestern Utah
<p>Measurement of bioturbation reflects physical and biological processes operating over time and can be used to reveal information about paleo-environments. The purpose of this study was to determine the intensity of bioturbation in Triassic Moenkopi Formation at Hurricane Mesa in Southwestern …

Early human adaptation in the northern hemisphere and the analytic implications of taphonomy
A comparative analysis is presented of faunal remains from six archaeological and six palaeontological open-air sites dating to the Lower and Middle Pleistocene. The presumed causal association between lithic tools and faunal remains at these early sites is evaluated, as is the presumed primary or …

Paleoecology and Taphonomy of Ediacaran macrofossils from the Khatyspyt Formation, Olenek Uplift, Siberia
… and methods for studying the paleoecology and taphonomy of Ediacaran macrofossils. The second chapter presents the results of a geochemical analysis to resolve taphonomic and paleoecological questions about the Ediacara-like discoidal holdfast fossil Aspidella. Stable isotope data of organic …

Paleobiology, Biostratigraphy, and Taphonomy of Neoproterozoic Eukaryotes and Cambrian Animals with Carbonaceous Preservation
… the paleobiology, biostratigraphy, and taphonomy of carbonaceous fossils in critical times of early life evolution, including Neoproterozoic and Cambrian. Chapters 2 to 5 in this dissertation present original research that helps to decipher hidden biological structures of various …

Taphonomy and Palaeoecology of multi-element skeleton invertebrates: a genetic model for exceptional preservation
The aim of the research is to improve the understanding on the origin of fossil accumulations by investigating their taphonomic and sedimentological features and by using stratigraphic data and the autecology of the organisms forming the shell beds. A number of highly different oligospecific high …

Taphonomy of a Lance Formation(Maastrichtian, WY) Dinosaur Bonebed with a Focus on Tooth Traces
<p>The Rose Quarry bonebed found in the Maastrichtian Lance Formation of eastern Wyoming possesses a complex blendof taphonomic signatures. Disarticulated, disassociated, fragmented bones of various states of abrasion from dinosaurs, turtles, and crocodilians are clustered together in a channelized …

Sedimentology and taphonomy of cenozoic vertebrates from Langebaanweg, Cape West Coast, South Africa; with palaeoecological interpretations
… and the lithology, sedimentology and taphonomy of remains recovered from the test pits was studied. The test pits were located in the sivathere bonebed, the 1976/2 excavation and in a new locality positioned 200 m to the south of the 1976/2 excavation. The depositional environment of …

Forensic taphonomy: investigating the post mortem biochemical properties of cartilage and fungal succession as potential forensic tools
Post mortem interval (PMI – the time elapsed since death and discovery) is important to medicolegal investigations. It helps to construct crucial time lines and assists with the identification of unknown persons by inclusion or exclusion of a suspect’s known movements. Accurate methodologies for …

THE IMPLICATIONS OF ATMOSPHERIC POLLEN RAIN FOR FOSSIL POLLEN PROFILES IN THE ARID SOUTHWEST (AEROBIOLOGY, PALAEOBOTANY, TAPHONOMY, PRESERVATION).
I compared atmospheric and soil pollen values to determine taphonomic influences on pollen in Southwestern soils. Burkard traps sampled atmospheric pollen for six years from multiple sites in Tucson, Arizona. Tauber and soil samples were collected for two years at Tumamoc Hill (Tucson). Morus, …

Heads, shoulders, knees and toes: Exploring bodies, body parts and personhood in late Neolithic Malta through funerary taphonomy
This research addresses the body and personhood in late Neolithic Malta (c. 3600–2300 cal BC) by reconstructing funerary practices at two collective burial sites: the Xemxija Tombs (Malta) and Xagħra Circle (Gozo). The range and sequence of funerary practices are identified through implementing …

Fluvial facies, vertebrate taphonomy and palaeosols of the Teekloof formation (Permian) near Beaufort West, Cape Province, South Africa
… facies analysis with investigations of the taphonomy of in situ therapsid fossils and the nature and distribution of palaeosols. Such an approach has not previously been applied to any of the Karoo strata. The results contain descriptive and quantitative information on sedimentary processes, …

Taphonomy, palaeoecology and taxonomy of an ophiuroid-stylophoran obrution deposit from the Lower Devonian Bokkeveld Group, South Africa
… Hex River Pass, Western Cape. In this study the taphonomy, taxonomy and the palaeoautecology of Palaeozoic ophiuroids and stylophorans was investigated using micro CT scans. Over 60 samples were scanned, manually segmented and stitched together to create a virtual 3D model of a portion of the …

The taxonomy and taphonomy in mio-pliocene and late middle pleistocene micromammals from the Cape west coast, South Africa
The study sites investigated in this thesis are situated along the southwest coast of South Africa in an area dominated by the sclerophyllous fynbos of the Strandveld and Sandveld, which supports a well-known micromammal (murid, soricid, macroscelid, bathyergid and chrysochlorid) fauna. This study …
