Eagle Owl (Bubo bubo) Pellets from Roman Sagalassos (SW Turkey): Distinguishing the Prey Remains from Nest and Roost Sites
-
Two concentrations of animal bones, almost exclusively from small mammals and wild birds, were found within the destruction debris of a Roman bath complex in Sagalassos (SW Turkey). The overall species spectrum, skeletal element representation, fragmentation and preservation condition of the bones indicate that they represent the prey remains of a large nocturnal avian predator, more precisely the eagle owl (Bubo bubo). Differences in skeletal element representation and in prey species’ spectrum show that the two bone clusters derive from pellets deposited near a nest site and a roost site, respectively. Radiocarbon dates obtained from the bones indicate that eagle owls lived in the collapsing bath complex during the second half of the 6th to the beginning of the 7th century AD, before the final abandonment of the town. The MNI of the prey animals found at the nest site, confronted with the daily dietary needs of a female eagle owl and its young, indicates repetitive use of the same place during several years.

Earliest Mysticete from the Late Eocene of Peru Sheds New Light on the Origin of Baleen Whales
-
Although combined molecular and morphological analyses point to a late middle Eocene (38–39 million years ago) origin for the clade Neoceti (Odontoceti, echolocating toothed whales plus Mysticeti, baleen whales, and relatives), the oldest knownmysticete fossil dates from the latest Eocene (about 34 million years ago) of Antarctica [1, 2]. Considering that the latter is not the most stemward mysticete in recent phylogenies and that Oligocene toothed mysticetes display a broad morphological disparity most likely corresponding to contrasted ecological niches, the origin of mysticetes from a basilosaurid ancestor and its drivers are currently poorly understood [1, 3–8]. Based on an articulated cetacean skeleton from the early late Eocene(Priabonian, around 36.4million years ago) of the Pisco Basin, Peru, we describe a new archaic tooth-bearing mysticete, Mystacodon selenensis gen. et sp. nov. Being the geologically oldest neocete (crown group cetacean) and the earliest mysticete to branch off described so far, the new taxon is interpreted as morphologically intermediate between basilosaurids and later toothed mysticetes, providing thus crucial information about the anatomy of the skull, forelimb, and innominate at these critical initial stages of mysticete evolution. Major changes in the morphology of the oral apparatus (including tooth wear) and flipper compared to basilosaurids suggest that suction and possibly benthic feeding represented key, early ecological traits accompanying the emergence of modern filter-feeding baleen whales’ ancestors.

Early Byzantine fish consumption and trade revealed by archaeoichthyology and isotopic analysis at Sagalassos, Turkey
-
We document the dietary and economic role of fish at Sagalassos, a town in ancient Pisidia (southwest Turkey) for the Early Byzantine period (c. 550 – 700 CE) through a detailed analysis of animal bones and stable isotopes. The role of fish in the diet is quantified, for the first time, based on large samples of sieved remains retrieved during the excavation of a number of spaces in an urban residence. The table and kitchen refuse from the mansion shows that fish was a regular part of the diet. However, past isotopic work focused on human individuals excavated in the city’s necropolises, slightly postdating the faunal remains examined, did not reflect this consumption of aquatic food. The studied assemblage comprises at least 12 different fish taxa, including five marine species, a Nilotic fish and six Anatolian freshwater species. Since the origin of the freshwater fishes could not be unambiguously determined by zoogeography alone, we analyzed carbon, nitrogen and sulphur stable isotope ratios in archaeological fish bones from Sagalassos as well as in bones of modern fish collected at different sites in Turkey. We show that most freshwater fish, i.e., all cyprinid species, came from Lake Eğirdir. No evidence was found for fish from the local Aksu River basin. The exact origin of pike, which account for 3% of all freshwater fish, could not be directly determined due to a shortage of modern comparative data. Using the data obtained on the provenance of the fish, the ancient trade routes possibly used in the Early Byzantine period are reconstructed using a combination of archaeological, numismatic and historical data on past commercial relations.
