Article Reference Diversity in pig husbandry from the Classical-Hellenistic to the Byzantine periods: An integrated dental analysis of Düzen Tepe and Sagalassos assemblages (Turkey)
Ethnographical, historical and archaeological evidence suggests that a great diversity in pig husbandry may have existed in the past. However, such diversity remains difficult to document from traditional zooarchaeological methods and its study may necessitate the implementation of combined methodological approaches. An integrated dental analysis, combining kill-off patterns, traditional and geometric morphometrics, linear enamel hypoplasia (LEH), microwear and stable isotope (δ18O,δ13C, δ15N) data, has been performed on assemblages from the neighbouring sites of Düzen Tepe and Sagalassos (SW Turkey) dated to Classical-Hellenistic to Byzantine time periods. Results indicate a diachronic evolution in slaughter practices, and a gradual decrease in pig mean size from the Early-Middle Imperial to the Byzantine. The seasonality of physiological stressing events remains the same, although their intensity varies through time. During the Early Byzantine period (CE 450–700), pig demographic management is characterized by two birth seasons, and a great diversity in diet and scale of management occurred, from free-ranging pigs – whether or not given food supplement - to closely confined wellwatered and more omnivorous pigs.

Article Reference The Rapid Spread of Early Farming from the Aegean into the Balkans via the Sub-Mediterranean-Aegean Vegetation Zone
Close examination of the geographic position of Early Neolithic settlements in SE-Europe shows that the oldest sites are almost exclusively situated in some very specific biogeographic areas. These earliest Neolithic settlements are all concentrated in a region that Pavle Cikovac calls the Sub-Mediterranean-Aegean biogeographic region. It covers the northern and north-western edge of the Aegean, including Thessaly, Greek Macedonia and Greek Thrace, and extends further into the Balkans, but only along the valleys rivers of the Vardar (Axios), Struma (Strymon) and Mesta (Nestos) rivers. Surprisingly, although Thrace is the closest landscape to Anatolia, it does not contain any sites of the earliest phase of the Neolithic at all beyond the narrow zone of the northern Marmara. In the present paper we explain this remarkable situation in terms of the natural environment in this particular region of the southern Balkans. To begin, we propose that the lack of oldest Early Neolithic settlements in Thrace is related to the extreme microclimate of this region. As shown by modern vegetation analogues, Thracian oriental hornbeam-downy oak forests are exposed to stronger continental influence with frosts in the winter and average temperatures during the coldest months that are ca. 2-3 °C lower than those in the Central Balkans that have Sub-Mediterranean vegetation. In general terms, what we may expect is that the earliest Neolithic groups would first appear in regions with similarly mild conditions, on a yearly average, to those in the Mediterranean. Such mild conditions are indeed present in the Sub-Mediterranean biogeographic region. On the other hand, before moving further to the north along the north-south oriented river systems of the Central Balkans, the Neolithic economy based on agriculture and stockbreeding would first have to be adapted to the relatively harsh winters in the Balkans. In consequence, it would have been possible to apply the new Neolithic lifestyle in the neighbouring areas of Thrace, Walachia, Dobrudža and the Carpathian Basin only after a certain period of adaptation. Available 14C-data show that the adaptation period is identical to the time-span of Rapid Climate Change (RCC: 6550-6050 calBC) as defined in previous studies.

Article Reference Fuel for debating ancient economies. Calculating wood consumption at urban scale in Roman Imperial times
Abstract Estimating wood extraction rates from forests based on archaeological and historical evidence is an important step in evaluating the sustainability of past social-ecological systems. In this paper, we present a calculation tool to estimate human wood resource use for a selected location during a defined period in the past. We illustrate the method by its application to the ancient town of Sagalassos (South-west Anatolia, Turkey) during the Roman Imperial period, with a focus on pottery production and the Roman Baths. Based on archaeological data, thermodynamic formulas and calorific values, an estimation is provided of the amount of wood used within a time step of one year. Because quantitative information on ancient technology and lifestyle is rather scarce and uncertain, input values consist of ranges. In order to take this uncertainty into account, a Monte Carlo procedure is included, offering a probability distribution of possible outcomes. Our results indicate that wood consumption in 2nd century Sagalassos was quite high, with a lifestyle including frequent hot bathing, export driven pottery production and a climate that required heating during winter months. Based on the available woodland area, we conclude that the community of Sagalassos was intensively using the surrounding forests.

Inproceedings Reference Vestibular sensitivity and locomotor behavior in early paleocene mammals
The end-Cretaceous extinction triggered the collapse of ecosystems and a drastic turnover of mammalian communities. During the Mesozoic, mammals were ecologically diverse, but less than extant species. Modern ecological richness was established by the Eocene, but questions remain about the ecology of the first wave of mammals radiating after the extinction. Postcranial fossils are often used to determine locomotor behavior; however, the semicircular canals of the inner ear also represent a reliable proxy. These canals detect the angular acceleration of the head during locomotion and transmit neuronal signals to the brain to allow stabilization of the eyes and head. Accordingly, vestibular sensitivity to rapid rotational head movements is higher in species with a larger canal radius of curvature and more orthogonal canals. We used high-resolution computed tomography scanning to obtain inner ear virtual endocasts for 30 specimens. We supplemented these with data from the literature to construct a database of 79 fossils from the Jurassic to the Eocene and 262 extant mammals. We compared data on canal morphology and another lifestyle proxy, the size of the petrosal lobules, which have a role in maintaining eyes’ movements and position. We find that Paleocene mammals exhibited a lower average and more constricted range of Agility Indices (AI), a new measure of canal radius size relative to body size, compared to Mesozoic, Eocene and extant taxa. In the early Paleocene, body mass and canal radius increased, but the former outpaced the latter leading to an AI decline. Similarly, their petrosal lobules were relatively smaller on average compared to other temporal groups, which suggests less ability for fast movements. Additionally, Paleocene mammals had similar AIs to extant scansorial and terrestrial quadrupeds. In contrast, the lack of canal orthogonality change from the Mesozoic to the Paleocene indicates no trend toward lower vestibular sensitivity regardless of changes in body size. This result may reflect functional differences between canal orthogonality and radius size. Our results support previous work on tarsal morphology and locomotor behavior ancestral state reconstruction suggesting that ground dwelling mammals were more common than arboreal taxa during the Paleocene. Ultimately, this pattern may indicate that the collapse of forested environments immediately after extinction led to the preferential survivorship of more terrestrially adapted mammals.

Article Reference Evolution of European carnivorous mammal assemblages through the Palaeogene
The rise of Carnivora (Mammalia: Laurasiatheria) is an important evolutionary event that changed the structure of terrestrial ecosystems, starting at the dawn of the Eocene, 56 Mya. This radiation has been mainly analysed in North America, leaving the evolution of carnivoran diversity in other regions of the globe poorly known. To tackle this issue, we review the evolution of terrestrial carnivorous mammal diversity (Mesonychidae, Oxyaenidae, Hyaenodonta and Carnivoramorpha) in Europe. We reveal four episodes of intense faunal turnovers that helped establish the dominance of carnivoramorphans over their main competitors. We also identify two periods of general endemism. The remaining time intervals are characterized by dispersals of new taxa from North America, Asia and Africa. The European Palaeogene carnivorous mammal fauna appears to have been almost constantly in a transient state, strongly influenced by dispersals. Many of the bioevents we highlight for European carnivorous mammals are probably best seen as ecosystem-wide responses to environmental changes. In contrast to the North American record, European hyaenodonts remain more diverse than the carnivoramorphans for the entire Eocene. The replacement of hyaenodonts by carnivoramorphans as the most diverse and dominant predators only occurred after the ‘Grande Coupure’ at 33 Mya, about 16 Myr later than in North America.

Article Reference Brawn before brains in placental mammals after the end-Cretaceous extinction
Mammals are the most encephalized vertebrates, with the largest brains relative to body size. Placental mammals have particularly enlarged brains, with expanded neocortices for sensory integration, the origins of which are unclear. We used computed tomography scans of newly discovered Paleocene fossils to show that contrary to the convention that mammal brains have steadily enlarged over time, early placentals initially decreased their relative brain sizes because body mass increased at a faster rate. Later in the Eocene, multiple crown lineages independently acquired highly encephalized brains through marked growth in sensory regions. We argue that the placental radiation initially emphasized increases in body size as extinction survivors filled vacant niches. Brains eventually became larger as ecosystems saturated and competition intensified.
