Badgers belong to the genus Meles Brisson, 1762, which comprise four extant species (M. anakuma Temminck, 1844, M. leucurus (Hodgson, 1847), M. canescens Blanford, 1875, and M. meles (Linnaeus, 1758)). The genus is included in the subfamily Melinae Bonaparte, 1838, a polyphyletic group of Eurasian mustelids whose evolutionary relationships need further clarification. The evolutive relationships of the genus are complex and far from being resolved. This work aims to describe a nearly 1 Ma unpublished badger mandible from the Sierra de Quibas (Murcia) and to help clarify the evolutionary patterns of Euroasiatic badgers. To this end, we used 2D geometric morphometric techniques to measure 57 landmarks and semilandmarks in 79 first lower molars (m1) of Meles, ranging from Pleistocene to extant species. Our results show evidence for differentiating between primitive badgers and living species of Meles. The new m1 of Meles from the Quibas site is more gracile (relatively narrower and longer) than the other Eurasian extinct species, and shows that this specimen can be placed in the subspecies M. meles meles (Linnaeus, 1758). Our results also show that the denomination of M. meles atavus Kormos, 1914 as a related subspecies with a primitive morphology is morphologically supported. Therefore, we conclude that the living subspecies of badger M. meles meles was already differentiated in the south of the Iberian Peninsula at around 1 Ma, but some primitive remnant populations persisted in the north of the Iberian Peninsula, for which we recognize the subspecies M. meles atavus.

Polycotylidae Cope, 1869 is a clade of short-necked plesiosaurians that achieved a cosmopolitan distribution by the Late Cretaceous. Here, the material previously referred to Polycotylidae/Pliosauridae from the Upper Cretaceous of New Zealand is reviewed, concluding that only 2.4% and 7.7% respectively of the total plesiosaurians specimens recovered in these formations (late Campanian-early Maastrichtian Tahora Formation and Campanian-Maastrichtian Conway Formation) belong to Polycotylidae. This proportion is similar to that recorded in upper Campanian-Maastrichtian levels of the Allen, Los Alamitos and La Colonia formations, northern Patagonia (Argentina) and southernmost Chile, but contrasts with the coeval absence of polycotylids in Campanian-Santonian levels of Antarctica and central Chile. These new results improve our knowledge about the representation of Weddellian polycotylids and underline the relative scarcity of Campanian-Maastrichtian records in the Weddellia Province.

This paper presents a case study from the Hiem cave (Hoà Bình province, North Vietnam) showing how a multidisciplinary approach in archaeological research can develop knowledge on the everyday life of the hunter-gatherer Hoabinhian groups occupying the cave during the early Holocene (8500-8200 cal BC). The archaeological analysis presents the characteristic Hoabinhian artefacts and their usage, while archeozoological, malacological and archaeobotanical research throw light on the way of life, including plant and animal elements of a daily diet as well as the settlement seasonality of the cave.

The long ranging Silurian retiolitines belonging to the Paraplectograptus lineage (Spirograptus turriculatus to Cyrtograptus/lundgreni Biozone), represented by the genera Paraplectograptus Bouček & Münch, 1952 and Pseudoplectograptus Obut & Zaslavskaya, 1983 are described in detail based on well preserved, three-dimensional material from the Canadian Arctic and Poland. For the first time, reconstructions of their structure are attempted, and comparisons are made with the related genera, Stomatograptus Tullberg, 1883 and Retiolites Barrande, 1850. Ultrastructural details vary somewhat between the genera: the bandaging on the Paraplectograptus lineage and Pseudoplectograptus has a characteristic pustulose ornament, while that of Retiolites and Stomatograptus shows a surface of longitudinal striations. Prosicular preservation is generally incomplete, represented merely by the prosicular apex and prosicular rim. The thecal part of the Paraplectograptus and Pseudoplectograptus tubaria (rhabdosomes) possesses transverse rods, connecting rods, lateral apertural rods and lips. The ancora sleeve lists are variably developed but lack a dorsal/zigzag list, which is present in Stomatograptus and Retiolites. The Paraplectograptus lineage appears to mark an intermediate stage in the evolution of the retiolitines, from the early Silurian forms, with strong thecal and ancora sleeve frameworks (e.g. Retiolites, Stomatograptus), to late Silurian descendants with strong ancora sleeves, minimal thecal frameworks and pustular ornament, with no transverse rods.
以Paraplectograptus bou & m nch(1952年)和Pseudoplectograptus Obut & Zaslavskaya(1983年)为代表的Paraplectograptus bou ek & m nch属和Pseudoplectograptus Obut & Zaslavskaya属为代表的志留纪长生代雷石石，根据加拿大北极和波兰保存完好的三维材料进行了详细描述。本文首次对其结构进行了重建，并与相关属(Stomatograptus Tullberg, 1883)和(Retiolites Barrande, 1850)进行了比较。不同属间的超微结构细节有所不同:Paraplectograptus和Pseudoplectograptus的包扎表面有典型的绒纹装饰，而Retiolites和Stomatograptus的包扎表面有纵向条纹。一般来说，隐泡保存不完整，仅表现为隐泡尖端和隐泡边缘。横纹肌旁和管状拟横纹肌(横纹肌体)的鞘部具有横杆、连接杆、侧孔杆和唇。ancora套筒表发育不一，但缺乏背/之字形表，这在Stomatograptus和Retiolites中是存在的。Paraplectograptus谱系似乎标志着雷顺石组进化的中间阶段，从志留纪早期的雷顺石(例如，雷顺石，Stomatograptus)，到志留纪晚期的雷顺石，有强大的雷顺石套，最小的鞘架和小泡装饰，没有横杆。

The present paper deals with the ecomorphological characteristics of two sympatric species of ictitheres: Ictitherium viverrinum Roth & Wagner, 1854 and Hyaenictitherium wongii (Zdansky, 1924) from the Late Miocene of the Eastern Mediterranean. These two species represent different taxonomic groups with allegedly distinct ecological roles. The values of 11 ecomorphological proxies were calculated using cranial and dental elements, in order to make an extensive comparison between them (body mass, bite force, canines’ and incisors’ bending strength, endocranial volume, relative rostral width, dental mesowear, intercuspid notches and carnassial vs grinding surfaces). The proxies show similar results for both species, pointing out that they had a similar ecological niche in the Late Miocene ecosystems. Carnivorans are usually in the top of the food chain, so the existence of two ecologically similar species in the same spatiotemporal range results in interspecific competition. This explains the geographical distinction of the two species with several localities being dominated by only one of the two (e.g. Samos for Hyaenictitherium Kretzoi, 1938 and Pikermi for Ictitherium Wagner, 1848). The reason for the prevalence of each genus can be associated with their postcranial morphology, as Hyaenictitherium has been proposed to be better adapted to chase hunting, because of its longer limbs, while Ictitherium is characterized by shorter and stouter limbs.

Mantis shrimps (Stomatopoda Latreille, 1817) are marine predatory crustaceans of the group Hoplocarida Calman, 1904 with an interesting, though incompletely known, evolutionary history. Here we introduce a new species of fossil mantis shrimps, Ostenosculda teruzzii n. gen., n. sp. from the Early Jurassic (Sinemurian) limestone formation of Osteno (Northern Italy). We present distinctive features that characterize the specimens as a new species, such as a unique arrangement of maxillipeds 2-5 (maxilliped 2 is the major raptorial appendage). We also present a phylogenetic systematic interpretation of the species based on the available features of morphology and body organisation. The unusual arrangement of the maxillipeds appears to represent a plesiomorphic condition relative to extant mantis shrimps: the maxillipeds are arranged in an almost straight anterior-posterior line, with rather large distances between them. This contrasts with extant forms and slightly younger fossils of about 150 million years old lithographic limestones (Late Jurassic) where further anterior maxillipeds are inserting far laterally and further posterior ones more medially, with very small distances between the next posterior ones. The herein studied specimens are the first of their kind to be confirmed for this period and geographical region and further close gaps in our understanding of the evolution of mantis shrimps.
螳螂虾(Stomatopoda Latreille, 1817)是一种海洋掠食性甲壳类动物，属于Hoplocarida Calman, 1904年，具有有趣的，尽管不完全了解的进化史。本文介绍了意大利北部奥斯蒂诺早侏罗世(Sinemurian)石灰岩地层中发现的螳螂虾化石的一个新种——osteosculda teruzzii n. gen.， n. sp.。我们提出了该标本作为新种的独特特征，如2-5肢的独特排列(2肢是猛禽的主要附属物)。我们还提出了基于形态学和身体组织的可用特征的物种的系统发育系统解释。相对于现存的螳螂虾，这种不寻常的颌足类排列似乎代表了一种非对称状态:颌足类排列在一条几乎笔直的前后直线上，它们之间的距离相当大。这与现存的形式和稍年轻的化石形成鲜明对比，这些化石大约有1.5亿年的历史(晚侏罗世)，在这些化石中，更前的颌足动物是向远处插入的，而更后的颌足动物是向中间插入的，后面的颌足动物之间的距离非常小。本文研究的标本是这一时期和地理区域首次确认的同类标本，进一步填补了我们对螳螂虾进化的认识空白。

Fossil remains herein described are referred to different species of Dasypodidae Gray, 1821 (Mammalia, Xenarthra, Cingulata) and come from the upper levels of the lower member (Late Miocene-Early Pliocene) of the Toro Negro Formation at Quebrada de Las Torrecillas, La Rioja Province, Argentina, where previous vertebrate records only include those of Pyramiodontherium scillatoyanei De Iuliis, Ré & Vizcaíno, 2004 (Mammalia, Xenarthra) and Opisthodactylus cf. kirchneri Noriega, Jordan, Vezzosi & Areta, 2017 (Aves, Rheidae). The remains of Dasypodidae herein presented include Vetelia ghandii Esteban & Nasif, 1996, Chasicotatus peiranoi Esteban & Nasif, 1996, Macrochorobates scalabrinii (Moreno & Mercerat, 1891), Prozaedyus sp., and Paleuphractus argentinus (Moreno & Mercerat, 1891), and constitute the first records of these species for the Toro Negro Formation, increasing the mammal diversity for this unit. The association of dasypodids here described shows strong affinities with those described for Late Miocene localities of Northwestern Argentina. Under these evidences, the Dasypodidae here reported for Quebrada de Las Torrecillas site show a characteristic association of taxa from Northwestern Argentina, suggesting a Messinian age (Late Miocene) for the bearing levels of the Toro Negro Formation. In this way, these records support the accurate ages recently proposed for the lower Member of the Toro Negro Formation (i.e., Late Miocene-Early Pliocene).
本文所描述的化石遗迹是指1821年Dasypodidae Gray(哺乳类，Xenarthra, Cingulata)的不同物种，来自阿根廷里奥哈省Quebrada de Las Torrecillas的Toro Negro组下部(晚中新世-上新世早期)的上层，其中先前的脊椎动物记录仅包括2004年的Pyramiodontherium scillatoyanei de Iuliis, r & Vizcaíno(哺乳类，Xenarthra)和约旦kirchneri Noriega的Opisthodactylus。Vezzosi & Areta, 2017 (Aves, Rheidae)。本文介绍的Dasypodidae的化石包括Vetelia ghandii Esteban & Nasif, 1996, Chasicotatus peiranoi Esteban & Nasif, 1996, Macrochorobates scalabrinii (Moreno & Mercerat, 1891)， Prozaedyus sp.和Paleuphractus argentinus (Moreno & Mercerat, 1891)，构成了这些物种在Toro Negro组的第一次记录，增加了该单元哺乳动物的多样性。这里描述的准足类的关联与阿根廷西北部晚中新世地区的关联有很强的亲缘关系。根据这些证据，在Quebrada de Las Torrecillas遗址发现的Dasypodidae显示了来自阿根廷西北部的分类群的特征关联，表明Toro Negro组的水平存在于迈西尼亚时代(晚中新世)。这样，这些记录支持了最近提出的托罗内格罗组下部(即中新世晚期-上新世早期)的准确年龄。

The specimen MLL-Pv-010 is composed of three articulated anterior-middle cervical vertebrae (with their respective ribs in position and an associated fourth rib), seven dorsal vertebrae with associated dorsal ribs, a distal caudal vertebra, a left scapula and the proximal end of a right scapula. The new specimen shows features, especially in the middle cervical vertebrae, that link it to Pilmatueia faundezi. Additionally, the specimen MLL-Pv-010 shows features previously unknown for the species, such as the morphology and orientation of the bifid neural spines of the anterior and mid-cervical vertebrae. The information obtained from the specimen MLL-Pv-010 allows us to propose an expanded diagnosis of Pilmatueia faundezi. Moreover, two phylogenetic analyses focusing on South American dicraeosaurids show that Pilmatueia Coria, Windholz, Ortega & Currie, 2019 is well nested within Dicraeosauridae Huene, 1927. One of our phylogenetic hypotheses differs from previous contributions in showing South American dicraeosaurids as a monophyletic group. However, in the second hypothesis these are not recovered as a natural group. We think that it is reasonable to recover a South American dicraeosaurid clade, and that eventually it will be best supported once more evidence is recovered.

The technocomplexes of the European Lower Palaeolithic are often attributed to the so-called Acheulean. Through several prehistoric sites located in the South Armorican coast, a distinct and contemporary Acheulean cultural facies was proposed at the end of the 1980s. Based on the study of lithic industries at the Pointe de Saint-Colomban site in Carnac, it is called “Colombanian” and is characterised by the coexistence of macro-tools on pebbles and a variety of small tools on flakes. As is often the case, the presence or absence of handaxes is a determining criterion to qualify a lithic assemblage as “Acheulean”. However, this categorial attribution loses all meaning when a technological analysis is conducted. Consequently, we used a techno-structural approach to illustrate the technological and functional variability of lithic artefacts from the early occupations of the Pointe de Saint-Colomban site (layers 5, 6 and 7). The application of the “chaîne opératoire” principle allowed us to reveal the processes and objectives of the lithic production system and to establish a homogeneous reading grid among the different pieces of the assemblage. We present here the data from our study which clearly shows that the “Colombanian” is no longer valid and that we need to initiate a change of definition. The lithic industry of the Pointe de Saint-Colomban site is dominated by the concept of flaking (débitage) represented by numerous cores and flake tools. The concept of shaping (façonnage) is illustrated by only two sandstone pebble tools. All this highlights the diversity and originality of the lithic technical systems of the Lower Palaeolithic of the Atlantic Armorican coastline.
欧洲旧石器时代晚期的技术复合体通常被归因于所谓的阿舍利人。通过位于南美洲海岸的几个史前遗址，一个独特的当代阿舍利文化相在20世纪80年代末被提出。根据对Carnac的Pointe de Saint-Colomban遗址的石器工业的研究，它被称为“哥伦比亚”，其特点是鹅卵石上的宏观工具和薄片上的各种小工具并存。通常情况下，手斧的存在与否是判定石器组合是否为“阿舍利”的决定性标准。然而，当进行技术分析时，这种分类归因就失去了所有意义。因此，我们使用技术结构方法来说明来自圣科伦班角遗址(第5层、第6层和第7层)早期职业的石器人工制品的技术和功能可变性。“cha ne opsamatoire”原则的应用使我们能够揭示石器生产系统的过程和目标，并在不同的组合中建立一个均匀的阅读网格。我们在这里提出我们研究的数据，这些数据清楚地表明“哥伦比亚人”不再有效，我们需要开始改变定义。Pointe de Saint-Colomban遗址的岩屑工业以大量岩芯和剥落工具为代表的剥落概念(d bitage)为主导。仅用两种砂岩卵石工具就说明了成形(far onnage)的概念。所有这些都突出了大西洋美洲海岸旧石器时代晚期石器技术系统的多样性和独创性。

The Neogene of Kutch, India is well known for its rich marine and terrestrial vertebrate assemblages. However, the data of piscean fauna from the middle Miocene of India is very scarce. We report here additional chondrichthyan and osteichthyan remains from the middle Miocene deposit of Chhasra Formation, Palasava site, Kutch, Gujarat, India. The elasmobranchs include Carcharhinus Blainville, 1816 (C. brevipinna (Müller & Henle, 1839), C. falciformis (Müller & Henle, 1839), C. cf. leucas, C. aff. perezi, Carcharhinus sp.), Negaprion Whitley, 1940 (Negaprion sp.), Aetobatus Blainville, 1816 (Aetobatus sp.), Myliobatis Cuvier, 1816 (Myliobatis sp.), Dasyatis Rafinesque, 1810 (D. probsti Cappetta, 1970, D. rugosa Probst, 1877), Himantura Müller & Henle, 1837 (H. menoni Sahni & Mehrotra, 1981), Pastinachus Rüppell, 1829 (Pastinachus sp.), and Taeniurops Garman, 1913 (Taeniurops sp.). The teleosts of Palasava are represented by four families including Bagridae Bleeker, 1858, Channidae Fowler, 1934, Characidae Latreille, 1925 and Cyprinidae Cuvier, 1817. Sørensen-Dice coefficient data of Palasava elasmobranchs show a good similarity index with their counterparts in the Mediterranean Sea suggesting the existence of short-lived reopening of the marine pathway. However, a much higher faunal affinity with those of Eastern Pacific indicates a gradual shift in migration path through the Pacific Ocean to Indo-Pacific region after the permanent landbridge was formed. The vertebrate fauna from the Palasava suggests a coastal, marginal marine, near-shore littoral to neritic environment of deposition with the influence of freshwater riverine system. The integration of the floras and faunas from Palasava locality indicates the presence of warm, humid/wet, tropical to sub-tropical environmental conditions during the middle Miocene.
