Human Palaeoecological Interactions and Owl Roosting at Tron Bon Lei,Alor Island,Eastern Indonesia

We report on tetrapod (Reptilia, Amphibia, Mammalia, Aves) vertebrates recovered during excavations at Tron Bon Lei rockshelter on the south coast of Alor Island, eastern Indonesia. These include both archaeological specimens recovered from a 1 m² test pit dating from ～21 kya cal BP to the late Holocene, and a modern eastern barn owl deposit recovered nearby. To discern between the depositional processes that accumulated the small numbers of micro- and macrovertebrate remains from the archaeological deposits, the taphonomic signature of the natural assemblage was quantified and compared to the archaeological record. The taphonomic data indicates that the tetrapod archaeofaunal remains are a combination of barn owl predation of microfauna and human predation of larger fauna. This approach provides new information on human-tetrapod interactions on Alor in Wallacea during the late Quaternary, including an apparent increase in cave site use and hunting intensity during the Pleistocene-Holocene transition, sea turtle butchery and probable transport, and extinctions of previously unknown giant to large rat species.     

Stone Age exploitation of birds on the island of Gotland,Baltic Sea: a taphonomic study of the avifauna on the Neolithic site of Ajvide

We have conducted a detailed taphonomic study of the avifauna of the Pitted Ware culture site of Ajvide on the Island of Gotland in the Baltic Sea, in order to investigate the fowling patterns and the taphonomic history of the bird remains. We have investigated cultural as well as natural modifications on the bird bones, fragmentation and fracture patterns, and performed a systematic surface modification study. No specific area for the deposition of bird remains or specific bird species was identified. All major anatomical parts of birds are present in the assemblage, but there is a dominance of specimens from the wing elements. Traces of cultural modification were observed on the bones, including cut marks, burning, modification (implements, beads, raw material), and gnawing marks. The bone surface modifications and fracture analysis indicate that the majority of the bird bones at Ajvide did not lie on the soil surface for an extended period of time before being deposited in the soil. Dry fractures increase while fresh fractures decrease towards the upper levels of the stratigraphy, indicating more extensive post‐depositional destruction. This may partly be connected to modern agriculture, but also to later use of the settlement area as a burial ground. The Ajvide assemblage contains a variety of birds living in different biotopes. However, bird hunting was mainly focused on sea birds. Auks and ducks are the most common families in the assemblage. We find it likely that the Ajvide hunters conducted organised hunting expeditions to two nearby islands for the hunting of auks, while it was possible to hunt other birds such as ducks closer to the site. The presence of medullary bone and bones from subadult birds indicates a main hunting season in late spring and early summer. However, comparisons with modern migration patterns indicate that hunting may have occurred throughout the year. Of special palaeozoological interest is the find of gannet (Morus bassanus), which apparently in Neolithic times visited the Baltic area more regularly than today.

A conceptual model for freshwater mussel (family: Unionidae) remain preservation in zooarchaeological assemblages

Expectations for survival of vertebrate remains have been well developed and intensely studied in the zooarchaeological taphonomic literature. Taphonomic studies of shellfish remains focus on marine species and on variables relevant to remains from paleontological contexts (e.g., fossil marine beds). In this paper we develop a conceptual framework from which to derive expectations concerning the preservation of freshwater mussel remains focusing on two parameters, shell microstructure and shell shape. Shell size does not influence survivorship. Our model is validated through application to late Holocene zooarchaeological mussel assemblages from north Texas. Taphonomically robust species are important regarding zooarchaeological and biogeographic interpretations based on mussel paleofaunas, and fragile species are important indicators of whether or not an assemblage is well preserved.     

Examining criteria for identifying and differentiating fossil faunal assemblages accumulated by hyenas and hominins using extant hyenid accumulations

Numerous authors have put forth criteria for distinguishing between assemblages collected by hyenas and hominins. Of the seven most recognised criteria used to distinguish hyenid from hominin assemblages, it has recently been suggested that four be rejected and three retained. The four rejected criteria are: an excessive proportion of horns and horn cores in hyena accumulated assemblages; the absence of small, hard, compact bones; mortality profiles; and the ratio of cranial bones to postcranial bones. The three criteria previous researchers suggested be retained are: a carnivore MNI ratio of ≥20%; an abundance of cylinder fragments; and hyena‐inflicted damage upon the bones. In this examination of over 27,000 faunal remains associated with all three species of extant bone‐collecting hyenids from four countries and two continents, six of the seven previously established criteria and reconsiderations of criteria have been evaluated. The results of the present study indicate that of the six criteria examined, none, as written, are indicative of hyenid activity on bone assemblages of unknown origin.

Taphonomy and interpretation: An analytical framework for social zooarchaeology

Taphonomy is central to many attempts to address social questions from archaeological animal remains, especially where those questions relate to practices of consumption and deposition. Without a clear analytical framework for this purpose, however, results can verge on the anecdotal. Following a review of the structure of taphonomy, this paper presents just such a framework designed to isolate archaeologically relevant patterns of behaviour through a comprehensive, quantitative analysis of numerous taphonomic variables. The typical formation processes shaping zooarchaeological assemblages are grouped into five broad stages and considered in reverse chronological order, allowing the analyst to work backwards towards the ‘death assemblage’ while identifying evidence of cultural practices. Particular attention is paid to differences between taxa, context types, phases, etc., that cannot be explained in mechanistic terms. This process is illustrated with selected data from a wider study of the Vinča (late Neolithic) site of Gomolava, Serbia, tracing the identification of one particular set of depositional practices.

Evidence for Differential Ancient DNA Survival in Human and Pig Bones from the Norse North Atlantic

Current models of DNA degradation and previous research on Icelandic human skeletons predict ancient DNA preservation in the Norse North Atlantic faunal remains to be excellent. In contrast, we found that DNA preservation in Viking‐Age pig remains was poor. We posit that this discrepancy in DNA survival between human and faunal remains is due to differing taphonomies. Our results highlight that DNA degradation is strongly dictated by micro‐environmental taphonomic processes even in regions where the climate is conducive to DNA survival. Due to these differences, DNA preservation in animal remains may not be suitable proxies for DNA preservation in associated human remains. Copyright © 2012 John Wiley & Sons, Ltd.     

Mammalian Microfaunal Remains from Khonkho Wankane (Late Formative Period), Mollo Kontu (Middle Horizon Period) and Pukara de Khonkho (Late Intermediate Period) in the Bolivian Altiplano

Paleoecological and taphonomic analysis of the mammalian microfauna from three Bolivian altiplano sites is presented: Khonkho Wankane [Late Formative period; number of identified specimens (NISP) = 1019], Mollo Kontu (Middle Horizon period; NISP = 610) and Pukara de Khonkho (Late Intermediate period; NISP = 165). The following species, all of which are present in this region today, were identified: Akodon boliviensis (Bolivian grass mouse), Andinomys edax (Andean mouse), Auliscomys sublimis (Andean leaf‐eared mouse), Cavia porcellus (guinea pig/cuy), Chinchilla chinchilla (chinchilla), Ctenomys leucodon (white‐toothed tuco‐tuco), Eligmodontia puerulus (Andean gerbil mouse), Galea musteloides (common yellow‐toothed cavy), Lagidium viscacia (vizcacha), Neotomys ebriosus (Andean swamp rat),and Oligoryzomys destructor (destructive pygmy rice rat). Some direct human involvement with the deposition of some of the larger species (Cavia porcellus, Chinchilla chinchilla, Ctenomys leucodon and Lagidium viscacia) was noted, although C. porcellus was identified only from a single element from Mollo Kontu. Most deposition was likely due to natural in‐burrow deaths and other natural attrition of these species. No significant shift in environment during the occupation of these sites was detected.

The Red Fox (Vulpes vulpes) as an Accumulator of Bones in Cave‐like Environments

Identifying the behavioural patterns of bone collecting animals is a crucial aspect of taphonomic studies. Although many studies have established criteria for identifying animal‐collected or animal‐modified bones, very few papers describe the distinguishing features of fox‐made bone assemblages. The bone assemblage collected in an inactive underground stone mine in Potok‐Senderki (Poland) is diagnostic of a red fox (Vulpes vulpes) den. This site provides an ideal opportunity to develop an understanding of the bone collecting behaviour of red foxes in cave‐like environments. This study showed that bones collected by red foxes are concentrated in clusters. The bones represent a broad spectrum of local fox prey species, with most bones showing the marks of gnawing. Each cluster may contain from <10 to >100 bones. Furthermore, the long axes of the bones in clusters frequently show specific orientation. The analysis of bones at this site might make an important contribution towards the establishment of baseline criteria for the identification and evaluation of fox‐accumulated bone assemblages.

Palaeoecology and palaeoenvironment of the Jurassic Talbragar Fossil Fish Bed,Gulgong, New South Wales,Australia

BEATTIE, R.G. & AVERY, S., December 2012. Palaeoecology and palaeoenvironment of the Jurassic Talbragar Fossil Fish Bed, Gulgong, New South Wales, Australia. Alcheringa 36, 451–465. ISSN 0311-5518.

The Talbragar Fossil Fish Bed has produced a significant number and variety of insect fossils, including the orders Hemiptera, Coleoptera, Orthoptera, Plecoptera, Odonata, Neuroptera, Diptera, Hymenoptera and Mecoptera. Hemiptera are the most common insects. Coleoptera are both common and diverse. Both orders include terrestrial and aquatic species. The other insect orders represented are less common. Many of the insect fossils discovered were previously unknown in the Australian region during the Jurassic, and the new records extend their palaeogeographic range into southeastern Gondwana. A recent collection of insects, fish, coprolites, gastropods, bivalves, bark, leaves, fruiting bodies, burrows and other ichnofossils supports a model of a shallow-water-lake palaeoenvironment at the northern end of the deposit, grading to a shoreline palaeoenvironment towards the southern end of the deposit. The existence of a productive lake supporting a large population of fish and a diverse, aquatic/shoreline and terrestrial woodland fringe palaeoecosystem, dominated by insects and woody plants, is demonstrated. There is no evidence of tetrapods. The Talbragar Fossil Fish Bed has similarities to Type A and B Mesozoic lake deposits reported from Transbaikalia. Culicimorph pupae are numerous and may have filled a significant niche near the base of the aquatic palaeoecosystem. Other immature aquatic insects are rare. The generally articulated nature of the fossil insects is interpreted to have resulted from a sudden but low-energy burial event.
