Article Reference New Archaeozoological Data from the Fayum ‘‘Neolithic’’ with a Critical Assessment of the Evidence for Early Stock Keeping in Egypt
Faunal evidence from the Fayum Neolithic is often cited in the framework of early stock keeping in Egypt. However, the data suffer from a number of problems. In the present paper, large faunal datasets from new excavations at Kom K and Kom W (4850–4250 BC) are presented. They clearly show that, despite the presence of domesticates, fish predominate in the animal bone assemblages. In this sense, there is continuity with the earlier Holocene occupation from the Fayum, starting ca. 7350 BC. Domesticated plants and animals appear first from approximately 5400 BC. The earliest possible evidence for domesticates in Egypt are the very controversial domesticated cattle from the 9th/8th millennium BC in the Nabta Playa-Bir Kiseiba area. The earliest domesticates found elsewhere in Egypt date to the 6th millennium BC. The numbers of bones are generally extremely low at this point in time and only caprines are present. From the 5th millennium BC, the numbers of sites with domesticates dramatically increase, more species are also involved and they are usually represented by significant quantities of bones. The data from the Fayum reflect this two phase development, with very limited evidence for domesticates in the 6th millennium BC and more abundant and clearer indications in the 5th millennium BC. Any modelling of early food production in Egypt suffers from poor amounts of data, bias due to differential preservation and visibility of sites and archaeological remains, and a lack of direct dates for domesticates. In general, however, the evidence for early stock keeping and accompanying archaeological features shows large regional variation and seems to be mainly dependent on local environmental conditions. The large numbers of fish at Kom K and Kom W reflect the proximity of Lake Qarun.

Article Reference New archaeozoological evidence for the introduction of the guinea pig to Europe
The remains are described of a guinea pig dated to the end of the 16th - beginning of the 17th c. AD. The animal was discovered at a site in Mons, Belgium, and is the first European archaeozoological find dated with certainty on the basis of both the archaeological context and a radiocarbon dating of its bone. This find confirms that the guinea pig was introduced to Europe soon after the conquest of South America. The morphological and metrical analyses performed on the skeletal remains are in agreement with the iconographic and literary sources indicating the domestic status of the animals imported to Europe. While a previous discovery in England suggested that the guinea pig was a prestigious animal, the present study argues that it was accessible to several classes of the population which may be related to the rapid spread of this prolific animal after its introduction in Europe.

Inproceedings Reference New bats (Chiroptera) from the Earliest Oligocene Boutersem-TGV locality in Belgium document the earliest occurence of Myotis
Early Oligocene mammals from Europe are not well known. In Belgium this interval (reference level MP 21) is represented by four coeval localities, Boutersem, Boutersem-TGV, Hoogbutsel and Hoeleden. Included in a vertebrate assemblage of 20+ mammalian genera, one bat, Quinetia misonnei, has been previously described from Hoogbutsel, based on four lower dentitions. Twenty new specimens of Quinetia were recently recovered from Boutersem-TGV including six upper molars, a humerus, and thirteen lower dentitions. These new specimens confirm that Quinetia is a plecotine vespertilionid and consequently represents the earliest known occurrence of this tribe. Additionally, twenty five other dental specimens document the presence of a larger vespertilionid from Boutersem-TGV. These specimens are assigned to Myotis based on the primitive 3.1.3.3 dental formula, the presence of a single-rooted p3, myotodont lower molars, a relatively high crowned lower canine with well-developed mesial and distolingual shelves, M1 and M2 lacking both paraconules and metalophs, protofossa of M1 and M2 open posteriorly, and M3 being relatively short. The Boutersem-TGV Myotis specimens represent the earliest known record of this extant genus. Only some isolated potential myotine teeth from Le Batut (MP 19) in France are older but these teeth differ from Myotis in having upper molars with a paraloph and a protofossa closed posteriorly, both features more typical of the enigmatic “Leuconoe”. Myotodont species, such as “L”. salodorensis from Oensingen (MP 25) in Switzerland and “L”. lavocati from Le Garouillas (MP 25-28) in France, both share features of upper teeth that distinguish them from Myotis. Younger still are three Myotis species from Herrlingen 8-9 (MP 29) in Germany. Compared to the Boutersem-TGV Myotis, M. minor is much smaller with a relatively smaller, shorter and more delicate p4, M. intermedius is somewhat smaller in molar dimensions but with a substantially smaller and shorter p4, while M. major has larger m1-2, similar sized m3, smaller p4, more robust M1 and a more constricted P4 lingual shelf. The origin of Myotis appears to be at least as old as the earliest Oligocene.

Article Reference New bio-chemostratigraphic dating of a unique early Eocene sequence from southern Europe results in precise mammalian biochronological tie-points
European early Eocene (Ypresian) mammalian biochronology, covering a timespan of about 8 myr, includes three distinct MP (Mammal Paleogene) reference levels MP7, MP8+9 and MP10. These are represented in the unique succession of the Minervois (Southern France) by the localities of Fournes (close to MP7), Sainte-Eulalie (close to MP8+9) and Azillanet (close to MP10). Considering homogenous terrestrial organic matter contribution (type III) as suggested by palynofacies and Rock-Eval pyrolysis, we here demonstrate that the organic carbon isotope curve of the predominantly continental Ypresian of the Minervois closely matches the marine standard carbonate carbon isotope curve. The here studied mammalian faunas and their supposed corresponding MP levels can thus be accurately dated and correlated on a global scale. The endemic Fournes mammal fauna, located just above the Eocene Thermal Maximum 2 - ETM2, is assigned to mid-Biochron NP11 (Calcareous Nannoplankton Zone). Accordingly, the Fournes mammal site is about 2.5 myr younger than the MP7 reference level of Dormaal (Belgium, latest Biochron NP9), about 1 myr younger than the MP7 mammalian locality of Le Clot in the Corbières (Southern France, late Biochron NP10 or early Biochron NP11) and very close to the Wasatchian Wa-5 mammalian biozone of Wyoming. A mid-Biochron NP12 age is inferred for the endemic Sainte-Eulalie fauna because of its position at the very top of (or just above) the isotopically negative “ETM3 interval”, whereas the Azillanet fauna, recorded at the top of a δ13Corg positive trend above the “ETM3 interval”, ranges from late Biochron NP12 to early Biochron NP13. Our results indicate that the short-term hyperthermals ETM2 and ETM3 did not affect the endemic character of the mammalian faunas in Southern and Northern Europe during the MP7 to MP8+9 interval. The end of this mammalian endemism likely occurred during the early phases of the EECO (Early Eocene Climatic Optimum) in early late Biochron NP12.

Article Reference New carnivoraforms from the Latest Paleocene of Europe and their bearing on the origin and radiation of Carnivoraformes (Carnivoramorpha, Mammalia)
We report the discovery of the earliest European carnivoraforms, based on two new taxa from the latest Paleocene of France and Romania. A new species of Vassacyon, V. prieuri, from the locality of Rivecourt (MP6b; Oise, France) (MP D Mammalian Paleogene reference levels) is described based on a dentary fragment and isolated teeth. This species displays several primitive features compared with species of Vassacyon known from the early Eocene of North America and Europe. A second Paleocene carnivoraform, cf. Gracilocyon sp., is described based on fragmentary specimens from the locality of Jibou (MP6b; Transylvania, Romania). Carnivoraformes were previously unknown in Europe before the Eocene, and Vassacyon prieuri and cf. Gracilocyon sp. are their oldest records in Europe. These discoveries favor the hypothesis of a dispersal of these two genera from Europe to North America during the Paleocene-Eocene Thermal Maximum. Vassacyon prieuri and cf. Gracilocyon sp. strengthen support for the level MP6b and its correlation with the Clarkforkian. The geographic origin of the Carnivoraformes remains unknown. However, based on the observed biochronological and geographic distributions of the carnivoraforms, we infer a possible Asian origin for this group. In this scenario, Gracilocyon and Vassacyon dispersed to Europe during the Clarkforkian MP6b time, probably together with rodent taxa, whereas Uintacyon dispersed from Asia to North America shortly after rodents and tillodonts

Article Reference New carnivoraforms from the early Eocene of Europe and their bearing on the evolution of the Carnivoraformes
Two new mammalian carnivoraform species, Uintacyon hookeri sp. nov. and Quercygale smithi sp. nov., are described from the early Eocene of Europe. U. hookeri sp. nov. is recorded in Mutigny (MP8 + 9, PE IV), Avenay (MP8 + 9, PE V), Brasles, Condé-en-Brie (MP8 + 9) and Cuis (MP 10), while Q. smithi sp. nov. comes from Mutigny and Mancy (MP10). Because the two species are not recorded in earliest Eocene localities such as Dormaal and Le Quesnoy (MP7, PE I), it is proposed that they dispersed after the main phase of the Mammal Dispersal Event. U. hookeri sp. nov. supports the existence of terrestrial connections with North America, while Q. smithi sp. nov. implies possible faunal exchange with Asia. This evidence for the evolution of the Carnivoraformes supports: (1) a rapid decrease in their diversity after the Mammal Dispersal Event; and (2) the existence of a mammal turnover event in Europe during the early Eocene. The discovery of a new species of Quercygale, which is generally considered as the closest carnivoraform to the crown-group Carnivora, shows that the genus had already lost the M3 by the early Eocene and supports an important, but very poorly known, radiation of the carnivoraforms at least during the earliest early Eocene.

Proceedings Reference NEW DATA AND A REVIEW OF THE HYAENODONTANS FROM THE PALEOGENE OF AFRICA
Hyaenodontida is a group of carnivorously adapted mammals, which was successful in the Paleogene of Africa. Contrary to Laurasian representatives, African hyaenodontidans had no ecological competitors until the late Oligocene. On one hand, the late Eocene and early Oligocene hyaenodontidans have been known since the beginning of 20th century thanks to the discovery of fossils from the Fayum area (Egypt). On the other hand, the Paleocene-Middle Eocene history of these predators was clarified only recently thanks to fieldwork in Northern Africa (Algeria, Morocco, and Tunisia). The recent discovery of the koholiine, Lahimia, in the Paleocene of Ouled Abdoun Basin (Morocco) allows the origin of the African hyaenodontidans to be traced as far back as the Selandian. A second Paleocene taxon is recorded in the Ouarzazate Basin (Morocco): Tinerhodon from the Thanetian. Lahimia and Tinerhodon interestingly display two distinct dental morphologies: Tinerhodon has very primitive dental features, while Lahimia is derived in the secant morphology of its molars and loss of P1. These differences can be explained by a presently unknown Paleocene radiation. The recent discoveries of hyaenodontidans in the late early or early middle Eocene of Gour Lazib area (Algeria) and middle Eocene-early Oligocene of Dur At-Talah (Libya) show that three new families appeared in Africa, at least during the middle Eocene: Apterodontinae, Hyainailourinae, and Teratodontinae. The postcranial material of Apterodon shows that hyaenodontidans even occupied a semi-aquatic niche in Africa. New fossils from Chambi, in Tunisia, show a common carnivorous fauna with the sites from Gour Lazib area. Interestingly, hyainailourines and teratodontines were also present in southern Africa (Sperrgebiet, Namibia; Lutetian); this is evidence that hyaenodontidans had a wide African distribution. Hyaenodontidans show a global trend of body size increase during the Paleogene. However, the recent discovery of the small hyaenodontidan Furodon in the Gour Lazib area and Chambi shows that small hyaenodontidans co-existed with large ones. Several hypotheses on hyaenodontidan origins in Africa were proposed. Some assume an endemic African origin, while others suppose several trans-Tethyan dispersals from Laurasia to Arabo-Africa. The best evidence is for the dispersal of endemic African hyainailourines and apterodontines in Europe around the Eocene-Oligocene boundary, participating in the renewal of the European carnivorous fauna at the ‘Grande Coupure’.

Article Reference New data on Barbatodon oardaensis Codrea, Solomon, Venczel & Smith, 2014, the smallest Late Cretaceous multituberculate mammal from Europe
Surprisingly, after the Early Cretaceous taxonomic diversity recorded in Europe, which probably is largely an artifact of inadequate taxonomy and inflation of taxa, multituberculate mammals became extremely scarce in the Late Cretaceous in this continent, being reported exclusively from the uppermost Cretaceous continental deposits of the so-called “Haţeg Island” in Transylvania, Romania. Such mammals have been documented from the Haţeg and Rusca Montană sedimentary basins, as well as from the southwestern area of the Transylvanian Basin. All these records belong to the endemic family Kogaionidae. The present paper reports additional data related to the smallest Cretaceous kogaionid, Barbatodon oardaensis Codrea, Solomon, Venczel & Smith, 2014 based on a series of new isolated teeth recovered mainly from the type locality, Oarda de Jos (Oarda A). Furthermore, the fossil locali-ties Oarda B and Vălioara are other new occurrences for the species. Based on this new material, the intraspecific variability of B. oardaensis is confirmed and its presence is attested in the three basins. Details related to the diversity of the “Haţeg Island” kogaionids are also provided.
