In the layers C4, C3 and C2, respectively from the oldest to the most Keywords: recent, terrestrial Helicidae mollusk shells (Helix aspersa) were dated by 14C. These layers also contained Giant deer many fragments of eggshell, belonging to Struthio cf. camelus, associated with mammal remains such as Extinction Oryctolagus/Lepus, Gazella sp., Sus scrofa, Ammotragus lervia, Alcelaphus buselaphus, Equus sp., Pha- Holocene cochoerus aethiopicus and an undetermined Caprini. Among these remains, an incomplete mandible of North Africa Speciation Megaceroides algericus Lydekker, 1890 with M1 and M2 was found in layer C3. The 6641 to 6009 cal BP Palaeoecology time range attributed to this layer has provided the most recent date known so far for M. algericus. In this study, we review and contextualize the findings of this particular species both in time and space and discuss its systematic position. We describe the morphology of the typical pachyostosic mandibular bone with the teeth and compare the dimensions with existing data. The assumption of the combined development, on the one hand, of the pachyostosic phenomenon and on the other hand, of the body weight fluctuations and growth of antlers for cervids strongly affected by seasonality is not supported. In order to understand the origin and the extinction of M. algericus, we examined the AMS radiocarbon dates available in the literature and calibrated them with RenDateModel software. Comparisons are then made with sea surface temperatures (e.g. GISP2 d18O), eustasy and related environmental changes throughout the time span of this species. Based on these data a possible migration route by the Strait of Gibraltar connected with with eustatic rises in sea-level rises are discussed. The speciation-extinction processes for M. algericus and their correlations with climatic shifts on a long time-scale in North Af- rica (e.g. Heinrich events, 8200 cal BP event) are also considered. Finally, this new discovery in Bizmoune cave clearly shows that M. algericus lasted until the very end of the Epipaleolithic, around 6000 cal BP (middle Holocene), whereas this species was formerly not believed to have survived until the early Epipaleolithic (around 8000 cal BP). © 2015 Elsevier Ltd and INQUA.

The cavern is formed within Upper Cretaceous limestone with an entrance that faces The cave of Bizmoune (834032.9900W/3140010.0200N; WGS 84) southwest. It is roomy and well-lit, measuring some 15 m deep by is located about 20 km southeast of Essaouira (Mogador) and was 10 wide. Test excavations in the cave in 2007 revealed the presence discovered in 2005 by A.

  • Megaloceros Giganteus) from the Pleistocene in Poland
    Palaeontologia Electronica palaeo-electronica.org Healed antler fracture from a giant deer (Megaloceros giganteus) from the Pleistocene in Poland Kamilla Pawłowska, Krzysztof Stefaniak, and Dariusz Nowakowski ABSTRACT We evaluated the skull of an ancient giant deer with a deformity of one antler. The skull was found in the 1930s in the San River near Barycz, in southeastern Poland. Its dating (39,800±1000 yr BP) corresponds to MIS-3, when the giant deer was wide- spread in Europe. Our diagnostics for the antler included gross morphology, radiogra- phy, computed tomography, and histopathology. We noted signs of fracture healing of the affected antler, including disordered arrangement of lamellae, absence of osteons, and numerous Volkmann’s canals remaining after blood vessel loss. The antler defor- mity appears to be of traumatic origin, with a healing component. No similar evaluation process has been described previously for this species.

Food habits of "Praemegaceros"cazioti (Depéret, 1897) from Dragonara Cave (NW Sardinia, Italy) inferred from cra­ nial morphology and dental wear. In ALCOVER, JA & BOVER, P. (eds.): Proceedings ofthe International Symposium "Insular Vertebrate Evo­ lution: the Palaeontological Approach': Monografies de la Societat d'Història Natural de les Balears, 12: 233-244. Resum S'ha estudiat l'adaptació alimentària de "Praemegaceros" cazioti (Depéret, 1897), en base a la rica mostra trobada als dipòsits del Pleistocè tardà de la cova de Dragonara (nord-oest de Sardenya, Itàlia). Amb aquest objecte, s'han pres en consi­ deració els trets cranials, així com el gradient de desgast d'abrasió - atrició (mesodesgast), i els efectes produïts a l'esmalt den­ tari per les particules contingudes als vegetals, per l'acidesa i/o duresa del menjar i per la força i direcció dels moviments mandibulars (microdesgast). Els resultats de les anàlisis qualitatives i quantitatives són consistents amb una adaptació alimentària a una dieta mixta, tal com també ho són algunes característiques cranio-dentàries: en particular, el morro, més aviat quadrat, les grans àrees d'inserció del musculus masseter, el desenvolupament de la prominència massetèrica sobre el M', la profunditat i altura del corpus i ramus a I' angulus mandibulae, la superfície d'inserció reduïda del musculus temporalis a la mandibula i les dents hipsodontes. Els resultats de la nostra anàlisi suggereixen que el cèrvid de la Cova Dragonara era un animal de dieta mixta, que va incrementar el consum d'herba en comparació amb el seu possible ancestre.

  • Deer from Late Miocene to Pleistocene of Western Palearctic: Matching Fossil Record and Molecular Phylogeny Data
    Zitteliana B 32 (2014) 115 Deer from Late Miocene to Pleistocene of Western Palearctic: matching fossil record and molecular phylogeny data Roman Croitor Zitteliana B 32, 115 – 153 München, 31.12.2014 Institute of Cultural Heritage, Academy of Sciences of Moldova, Bd. Stefan Cel Mare 1, Md-2028, Chisinau, Moldova; Manuscript received 02.06.2014; revision E-mail: [email protected] accepted 11.11.2014 ISSN 1612 - 4138 Abstract This article proposes a brief overview of opinions on cervid systematics and phylogeny, as well as some unresolved taxonomical issues, morphology and systematics of the most important or little known mainland cervid genera and species from Late Miocene and Plio-Pleistocene of Western Eurasia and from Late Pleistocene and Holocene of North Africa. The Late Miocene genera Cervavitus and Pliocervus from Western Eurasia are included in the subfamily Capreolinae. A cervid close to Cervavitus could be a direct forerunner of the modern genus Alces. The matching of results of molecular phylogeny and data from cervid paleontological record revealed the paleozoogeographical context of origin of modern cervid subfamilies. Subfamilies Capreolinae and Cervinae are regarded as two Late Miocene adaptive radiations within the Palearctic zoogeographic province and Eastern part of Oriental province respectively. The modern clade of Eurasian Capreolinae is significantly depleted due to climate shifts that repeatedly changed climate-geographic conditions of Northern Eurasia. The clade of Cervinae that evolved in stable subtropical conditions gave several later radiations (including the latest one with Cervus, Rusa, Panolia, and Hyelaphus) and remains generally intact until present days. During Plio-Pleistocene, cervines repeatedly dispersed in Palearctic part of Eurasia, however many of those lineages have become extinct.

Biogeographic relationships of Pliocene and Pleistocene North-western African Mammals Denis GERAADS CNRS – UPR 2147 – 44 rue de l’Amiral Mouchez – F-75014 PARIS [email protected] tel 33 1 43 13 56 21 fax 33 1 43 13 56 30 Abstract North-western Africa, today included in the Palaearctic realm, is well separated from the Ethiopian province by the Sahara, but the distribution of large mammals shows that these biogeographic domains cannot simply be extrapolated to the late Cenozoic. In the latest Miocene and earliest Pliocene, there were close connections with central Africa, but also remarkable similarities with East Africa, in some instances reaching the species level. There is no evidence of northern influence among large mammals, although several small mammals had a wide range in the Mediterranean.

    Science in China Series D: Earth Sciences © 2007 SCIENCE IN CHINA PRESS Springer Occurrences of warm-adapted mammals in north China over the Quaternary Period and their paleo- environmental significance TONG HaoWen Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, Beijing 100044, China (email: [email protected]) The north and south China faunas are subdivided along the line of Huaihe River-Qinling Mountains- Hengduan Mountains-Himalayas, to the north is the Palearctic Region, and to the south is the Oriental Region, which is the result of long-time evolution. Hundreds of Quaternary fossil localities have been known up to now, more than 60 of which contain warm-adapted elements which can be referred to 20 species. Among the warm-adapted elements appearing in north China, Hystrix, Macaca, Palaeoloxodon, Dicerorhinus and Bubalus are the most frequently recorded genera. There are three kinds of causal explanation about the frequent appearance of warm-adapted elements in north China: The first hy- pothesis attributed them to the dispersal events of warm-adapted mammals from the south during warm stages or warm seasons; the second scenario thinks that these warm-adapted mammals in north China were once derived there in situ and subsequently emigrated to the south with the cooling down of the global climate; the last hypothesis believes that these warm-adapted elements were not real warm-climate animals at that time. This study shows that almost none of the warm-adapted mammals in north China was recovered in the loess, and also almost all of the fossil localities which bear warm-adapted mammals fall within the warm temperate zone of nowadays.
