Preliminary results of the bioarchaeological research at the Neolithic site of Mursalevo (S Bulgaria): evidence on food storage, processing and consumption form the building contexts
-
Archaeozoological and archaeobotanical evidence from domestic contexts at the Early and Late Neolithic site of Mursalevo was used to explore food consumption and storage practices, subsistence strategies and exploitation of natural resources. Bioarchaeological evidence indicates diachronic changes of herd management and crop cultivation. During the Early Neolithic breeding of domesticates was focused on the production of meat, and crop assemblages point towards good growing conditions. In the Late Neolithic, herd management involved also milk production, with a larger contribution of cattle, while the dominating crops included mainly cereals and pulses that were adapted to unfavorable conditions. In addition, wild resources were less intensively used through time

A New Mammal Skull from the Late Cretaceous of Romania and Phylogenetic Affinities of Kogaionid Multituberculates
-
Among the Late Cretaceous fossil sites of Europe, only those from the so-called “Haţeg Island” in Transylvania, western Romania, are remarkable by their abundance in mammal remains. Curiously, all of them belong to a single family of multituberculates, the Kogaionidae, one of the rare families that survived the Cretaceous-Paleogene mass extinction in Europe. Kogaionids are mostly represented by isolated teeth except for three partial large skulls from the Maastrichtian Sânpetru Formation of the Haţeg Basin that have been described from the Sânpetru locality as Kogaionon ungureanui and from the Pui locality as Barbatodon transylvanicus and Litovoi tholocephalos. Here we report for the first time the discovery of a partial skull associated with p4 of a small-sized kogaionid from the Nălaţ-Vad locality in the Sânpetru Formation that we refer to Kogaionon radulescui, sp. nov. An updated phylogenetic analysis, including seven Maastrichtian and Paleocene kogaionids is performed and confirms that Kogaionidae is a monophyletic clade at the base of Cimolodonta. Kogaionon differs from Barbatodon in its narrower snout, proportionally smaller P1, narrower anterior part of P4 with four similar-sized cusps in the middle row, more squared or rounded M1 with an anteroposteriorly longer lingual row, and shorter p4 (at least for K. radulescui). Litovoi tholocephalos is here considered to be a junior synonym of B. transylvanicus. Despite their Maastrichtian age, the very simple and conservative dental morphology of these Romanian kogaionids suggests that they originated from an eobaatarid-like ancestor dispersing from Asia or possibly already existing in Europe between the Barremian and Albian, 40 to 55 Ma earlier.

A new partial skeleton of Kryptobaatar from the Upper Cretaceous of Bayan Mandahu (Inner Mongolia, China) relaunch the question about variability in djadochtatherioid multituberculate mammals
-
A new well-preserved partial skeleton of the djadochtatheriid multituberculate Kryptobaatar is here described from the Campanian Bayan Mandahu Formation of the southern Gobi Basin in Inner Mongolia, China. We refer to it as Kryptobaatar sp. because it presents characters that are specific to Kryptobaatar dashzevegi and others specific to Kryptobaatar mandahuensis, as well as characters of its own. When those taxa are incorporated into a phylogenetic analysis of the Djadochtatherioidea, the Kryptobaatar species appear to be paraphyletic. This raises again questions about the high intraspecific variability in some multituberculates. Based on a comparison with the published specimens, we conclude that K. mandahuensis is a valid species, close to but distinct from K. dashzevegi. Our results also suggest that endemism alone in the Gobi Basin is not the cause of the high variability observed in the genus Kryptobaatar. But the impact of a possible difference in age or paleoenvironment between the different Kryptobaatar-bearing sites of the Gobi Desert is, for the moment, not possible to test in the current state of knowledge.

Original articleSystematics and diversity of the giant soft-shelled turtles (Cryptodira,Trionychidae) from the earliest Eocene of Belgium
-
In 1909, the famous paleontologist Louis Dollo identified two putative new species of giant soft-shelled turtles from the lowest Eocene record of Belgium, ‘Trionyx erquelinnensis’ and ‘Trionyx levalensis’, from Erquelinnes and Leval, respectively. However, these proposals did not meet the requirements of the International Code of Zoological Nomenclature, so they were considered as nomina nuda. The information on these specimens or about any other specimen of this lineage of giant turtles from the Belgian record is currently extremely limited. Relatively scarce material from giant trionychids has been described for the lower Eocene record of other European regions. Considering the available information, all the European material has recently been recognized as belonging to the genus Axestemys, which has a North American origin, and possibly attributable to a single species, Axestemys vittata, which currently lacks a diagnosis. Numerous and well-preserved Belgian specimens are deposited in the Royal Belgian Institute of Natural Sciences. In addition to the cited individuals from Erquelinnes and Leval, additional specimens from both localities, as well as others from Orp-le-Grand, are part of this collection. These specimens, found between the decades of 1910 and 1930, have been recently restored, and their study is carried out here. The presence of Axestemys vittata in Belgium (in Leval and Orp-le-Grand) is confirmed. Knowledge about this species is significantly improved, and a diagnosis is proposed. However, the hypothesis proposed by Dollo is here confirmed, this species being not the only identified in the Belgian record. So, Axestemys erquelinnensis nov. sp. is defined based on the carapace from Erquelinnes known by Dollo, suggesting that the genus probably reached Europe during the Paleocene Eocene Thermal Maximum.

Carbon and nitrogen isotopic ratios in archaeological and modern Swiss fish as possible markers for diachronic anthropogenic activity in freshwater ecosystems
-
The aim of this study is to investigate isotopic variability in archaeological (n=85) and modern (n=29) freshwater fish specimens from Switzerland. Here, carbon (δ13C) and nitrogen (δ15N) stable isotope ratio analysiswas performed on bone collagen samples of pike (Esox lucius), perch (Perca fluviatilis), barbel (Barbus barbus), roach (Rutilus rutilus) and carp (Cyprinus carpio) fromeleven archaeological (11th to 18/19th centuries CE) andmodern sites. The archaeological vs. modern fish data revealed significant isotopic differences for pike, perch and barbel (δ13Cp≤ 0.03; δ15Np≤ 0.008), and provides possible evidence for a temporal change in Swiss aquatic ecosystems from Medieval to modern times. In comparison to archaeological fish (δ13C mean ± SD; −23.3 ± 1.6‰; δ15N mean ± SD; 8.3 ± 1.8‰), the modern fish samples show decreased δ13C and increased δ15N values (δ13C mean± SD; −27.4 ± 2.3‰; δ15N mean± SD; 12.5± 4.1‰) that can be associated with anthropogenic effects: fossil fuel combustion, deforestation and organic waste in the form of sewage and fertilizers. The isotopic signatures of archaeological fish remains indicate a local fishery practice, but also the exploitation of distant fishing grounds and freshwater fish transportation. Furthermore, a diachronic isotopic trend is observed in young perch from sites in Basel, dating between the 12th and 15/16th centuries CE, and the isotopic data from the Rhine freshwater fish (18/19th century CE) suggests that a significant shift in the river's trophic state was possibly caused by organic pollution fromurban and industrial wastewater. This retrospective research illustrates possible natural processes and human activitieswhich can cause differences in fish stable isotope data and highlights the ability to elucidate changes in past bodies of water. Furthermore, this study provides an interpretative framework for additional palaeoenvironmental studies and modern restoration projects focused on freshwater ecosystems.
