Sixteen small samples of fragmentary “chlorite” containers, coming from three different workshop sites of the Konar Sandal South network (Iran), were analyzed using a multianalytical approach, consisting in thin-section petrography and mineralogical characterization by X-ray powder diffraction. This preliminary study singled out at least two major different mineralogical groups, suggesting that different craft groups, possibly in different times, exploited different local sources of chloritic rocks. Results also indicates that the surroundings of Konar Sandal South, the main urban hub of the Halil valley, were involved – probably for several centuries – in the production of three major different classes of stone pots (cylindrical vessels with intricate geometric patterns, plain bell-shaped bowls and incised série récente vessels).
研究人员采用薄片岩相学和 X 射线粉末衍射矿物学特征描述等多分析方法，对来自科纳尔沙尔南网络（伊朗）三个不同作坊遗址的 16 个 "绿泥石 "容器碎片小样本进行了分析。这项初步研究确定了至少两大不同的矿物学组别，表明不同的工艺组别可能在不同时期开采了当地不同来源的绿泥石。研究结果还表明，科纳尔-桑达尔南区（哈利勒河谷的主要城市中心）周边地区--可能有几个世纪--参与了三大类不同石器的生产（带有复杂几何图案的圆柱形器皿、朴素的钟形碗和刻有刻纹的圆形器皿）。

The paper provides an overview of the Chilotherium Ringström, 1924 fossils from Romania, which are recorded so far in three different Upper Miocene localities of the Eastern Carpathians Foreland: mammal localities of Reghiu, Bacău and Pogana. The fossils include a partial skull, several maxillary and mandible fragments and isolated teeth. They have been partially illustrated, but never described excepting the isolated teeth of Pogana. The previous assignments were confusing, ranging from Chilotherium schlosseri (Weber, 1905) and C. cf. sarmaticum for Reghiu specimens to an indeterminate species close to C. sarmaticum Korotkevich, 1958, C. kiliasi (Geraads & Koufos, 1990), and C. kowalevskii (Pavlow, 1913) for Pogana teeth. Based on descriptions and comparisons with other Chilotherium remains, all specimens from Romania can be referred to C. schlosseri. Chilotherium schlosseri is the most widespread species of the genus, ranging from Eastern Europe to Central Asia. The presence of this genus in Romania, and more globally in Eastern Europe, attests to a transition area between the more closed and wooded environments of Western Europe (where Chilotherium is absent) to the more open ones in Asia.
本文概述了罗马尼亚的 Chilotherium Ringström, 1924 年化石，这些化石目前记录在东喀尔巴阡山前缘三个不同的上新世地点：雷吉乌、巴卡乌和波加纳的哺乳动物地点。这些化石包括一个部分头骨、几块上颌骨和下颌骨碎片以及个别牙齿。这些化石已被部分图解，但除了波加纳的个别牙齿外，从未被描述过。以前的归属很混乱，从雷丘标本的 Chilotherium schlosseri（韦伯，1905 年）和 C. cf. sarmaticum，到接近 C. sarmaticum Korotkevich，1958 年的不确定物种、C. kiliasi（Geraads & Koufos，1990 年），以及波加纳牙齿的 C. kowalevskii（Pavlow，1913 年）。根据描述和与其他 Chilotherium 遗骸的比较，罗马尼亚的所有标本都可以归为 C. schlosseri。Chilotherium schlosseri 是该属中分布最广的物种，分布范围从东欧到中亚。该属在罗马尼亚以及更广泛的东欧地区的存在，证明了西欧（没有 Chilotherium 的地区）较为封闭和树木繁茂的环境与亚洲较为开阔的环境之间的过渡区域。

The Eocene-Oligocene transition marks a period of dramatic global climatic change correlated with pronounced mammalian faunal change. Fossil evidence is indispensable for studying the distribution of taxa through time, and determining how abiotic parameters shaped ancient biodiversity. Here we report ruminant artiodactyls and a new anthropoid primate from Süngülü, a locality in Eastern Anatolia that has yielded a diversified and largely endemic assemblage of rodents. Three taxa of ruminants are recognized, the tragulid Iberomeryx parvus Gabunia, 1964, a larger species of Iberomeryx Gabunia, 1964, and a bachitheriid referred to cf. Bachitherium sp. A lower molar is identified as the new eosimiid primate Sungulusimias unayae n. gen., n. sp., which is the first occurrence of Paleogene anthropoids in western Asia. The lower molar of Sungulusimias unayae n. gen., n. sp. is characterized by protoconid and metaconid closely spaced and of similar height and volume, paraconid cuspidate and nearly connate with metaconid, strong mesiobuccal cingulid, and entoconid without strong connection to hypoconulid via the postcristid. The composition of this assemblage together with rodents indicates a probable Latest Eocene age for Süngülü, although an early Oligocene age cannot be completely ruled out. The rodent fauna from Süngülü suggests that endemism persisted at the periphery of Balkanatolia until the latest Eocene while Eastern Anatolia was situated in a strategic corridor for faunal exchanges between eastern Asia, Indo-Pakistan and Europe. During the Eocene-Oligocene transition, Balkanatolia probably functioned as a “holding pen” where various taxa were confined for significant intervals of time before proceeding to colonize Western Europe at the Grande Coupure.
始新世-更新世过渡时期标志着一个与哺乳动物群明显变化相关的全球气候剧变时期。化石证据对于研究分类群在不同时期的分布以及确定非生物参数如何影响古代生物多样性是不可或缺的。在这里，我们报告了产自东安纳托利亚苏恩居鲁（Süngülü）的反刍半齿兽和一种新的拟人灵长类动物。发现了三个反刍动物类群，分别是Iberomeryx parvus Gabunia（1964年），Iberomeryx Gabunia（1964年）的一个较大的物种，以及Bachitheriid（与Bachitherium sp.同属）。Sungulusimias unayae n. gen., n. sp.的下臼齿的特征是原齿和元齿间隔很近，高度和体积相似，副齿骤尖，几乎与元齿合生，中颊齿较强，内齿通过后嵴与下齿没有很强的联系。该动物群与啮齿类动物群的组成表明，Süngülü的年代可能为晚始新世晚期，但也不能完全排除早渐新世的可能性。来自 Süngülü 的啮齿动物群表明，巴尔干托利亚周边地区的地方性一直持续到晚始新世，而东安纳托利亚则位于东亚、印巴和欧洲之间动物交流的战略通道上。在始新世-更新世过渡期间，巴尔干亚托利亚可能起到了 "收容所 "的作用，各种类群在这里被收容了相当长的一段时间，然后才开始在大飓风时期向西欧殖民。

Matamata turtles (Chelus Duméril, 1806) are composed of two extant species, Chelus fimbriata Schneider, 1783 and Chelus orinocensis Vargas-Ramírez, Caballero, Morales-Betancourt, Lasso, Amaya, Martínez, Silva-Viana, Vogt, Farias, Hrbek, Campbell & Fritz, 2020, inhabitants of the main freshwater drainages of northern South America. The systematics and palaeobiogeography of Chelus is still unresolved. Here, we describe several new fossil specimens from the Late Miocene of Urumaco (Venezuela) and Tatacoa (Colombia). The fossils are mostly complete, articulated shells that allow reestablishing validity of two extinct taxa, Chelus colombiana Wood, 1976 and Chelus lewisi Wood, 1976. One of the specimens of C. lewisi from Urumaco represents the first record within the genus for which autopodial bones (a left manus) and additional limb bones are preserved together with ashell, demonstrating evolutionary conservatism in limb anatomy for the genus. The specimen comes from the Socorro Formation, representing the earliest so far known record of Chelus for the Urumaco sequence. Additionally, one specimen from Tatacoa is the first fossil for which cervical and pectoral girdle elements are preserved. Phylogenetic analysis supports the existence of two separate clades inside of Chelus, one formed by the extinct species and the other by the extant ones.

The hominoid Ouranopithecus macedoniensis (Bonis, Bouvrain, Geraads & Melentis, 1974) is known from three Late Miocene localities in Greece. All are correlated with late Vallesian, MN10; more precisely, they are dated between 9.6 and 8.7 Ma. During the last 50 years several fossils of this hominoid have been recovered. The present article describes the first specimen with upper deciduous teeth, recovered from the locality Ravin de la Pluie in Axios Valley (Macedonia, Greece). The upper deciduous dentition of O. macedoniensis is characterised by a small canine relative to the length of the deciduous premolars, with a rounded occlusal crown outline, a trapezoidal dP3 with metacone and a rudimentary hypocone, a sub-squared dP4, and the absence of cingulum. The taxonomic and sexual attribution of the studied material is based on the preserved and virtually reconstructed permanent dentition, using high resolution microcomputed tomography. The morphological and metrical comparisons of the permanent dentition with the available sample of O. macedoniensis, as well as the monospecific character and the strong sexual dimorphism of the Ravin de la Pluie sample, allow its attribution to a female sub-adult individual of this taxon. The upper deciduous teeth of Ouranopithecus macedoniensis preserve some morphological features, that may have a phylogenetic value, but this hypothesis requires further investigation as the available material of all fossil taxa is poor.
原始人马其顿乌古猿(Bonis, Bouvrain, Geraads &Melentis, 1974)在希腊的三个晚中新世地区被发现。均与晚瓦利西亚期有关，MN10;更准确地说，它们的年代在9.6到8.7 Ma之间。在过去的50年里，这种人科动物的一些化石已经被发现。本文描述了在希腊马其顿阿克索斯山谷的Ravin de la Pluie地区发现的第一个具有上乳牙的标本。O. macedoniensis的上乳牙列的特征是相对于乳牙前臼齿的长度而言犬齿较小，具有圆形的咬合冠轮廓，具有后锥体和初级下锥体的梯形dP3，亚方形dP4和缺乏带。研究材料的分类和性别归属是基于保存和虚拟重建的永久牙列，使用高分辨率微计算机断层扫描。通过与现有的O. macedoniensis样本的形态学和测量比较，以及Ravin de la Pluie样本的单特异性特征和强烈的性别二态性，可以将其归属于该分类单元的一个女性亚成年个体。马其顿Ouranopithecus macedoniensis的上乳齿保留了一些形态特征，这可能具有系统发育价值，但由于所有化石分类群的可用材料都很差，这一假设需要进一步研究。

Data on turtle limb bone histology and microstructure are spotty, especially for Mesozoic taxa, despite significant progress made in recent years. Here we provide first detailed information on the stylopodia of the Late Triassic stem turtles Proganochelys quenstedtii Baur, 1887 from Switzerland and Proterochersis porebensis Szczygielski & Sulej, 2016 from Poland. In both taxa we observed large, internal medullary regions filled with endosteal trabeculae and poorly to moderately vascularized parallel-fibered (grading locally to lamellar) periosteal cortices. Primary vasculature is predominantly longitudinal, in Proterochersis porebensis locally with radial inclination. In large specimens, secondary remodeling is significant in the deeper cortex, but it neither completely obliterates the primary tissue nor reaches the external surface of the bone in either taxon. Comparison of histological data, limb morphology, shell and limb lengths as well as proportions reveal differences in growth patterns between the taxa: Proganochelys quenstedtii seems to grow faster during early life stages than Proterochersis porebensis and attained distinctly larger body sizes earlier in ontogeny, even though the asymptotic body size is roughly the same for both species. Overall, the histological and microstructural characteristics of stylopodial bones of Triassic turtles more closely resemble those of more recent representatives of that group than earlier stem turtles.

This present work reports new data on the palaeohistology of Chañares Formation (early Carnian) proterochampsids based on appendicular bones, particularly Chanaresuchus bonapartei Romer, 1971 (i.e., PULR-V 116, femur, tibia and fibula) and Tropidosuchus romeri Arcucci, 1990 (i.e., PVL-4606, femur), and provides new insights into their paleobiology, histovariability, as well as lifestyle. Chanaresuchus bonapartei presents intraspecific and interelemental histovaribility with collagen fibers organized from lamellar to woven fibered bone tissue, and degree of vascular density from sparse to dense. Both specimens appear to have attained sexual and skeletal maturity, but somatic maturity could not be inferred. Tropidosuchus romeri presents intraspecific histovaribility with collagen fibers organized from parallel-fibered to woven fibered bone tissue, and dense vascularization. The lifestyle analysis for T. romeri, using a statistical model that employs anatomical and microanatomical data, suggests a terrestrial habit. The Proterochampsidae Romer, 1966 recovered from the Chañares Formation exhibits a large disparity in growth strategies among individuals of the same taxa, and with respect to other contemporaneous Archosauriformes.

Millipedes have a long evolutionary history, with the oldest presumed fossils of Diplopoda de Blainville in Gervais, 1844 being from the Silurian and the first definite fossil record originating from Devonian deposits. The phylogeny of Diplopoda is not fully resolved yet, especially not concerning fossil representatives. At the same time, already in the Palaeozoic millipedes showed quite a morphological and presumably also ecological variety. We describe here a new species of a Carboniferous millipede from the Westphalian A of the Netherlands, Lauravolsella willemeni n. gen., n. sp., a possible representative of Archipolypoda (†Archipolypoda Scudder, 1882). The species is based on a single specimen, preserved with part and counterpart, which both show a three-dimensional preservation. The specimen has unusually long tergites, in normal life position covering most of the following segment. These long tergites might have been beneficial when performing defensive enrolling. In extant millipedes, enrolling is usually facilitated by softer areas between the sternites, allowing for a certain degree of ventral compression. In the new fossil, the sclerotic sternites occupy the entire length of the ventral side of the segment, not allowing for any type of compression. The new fossil therefore demonstrates another solution for the mechanical challenges during enrolment and increases the morphological diversity of Carboniferous millipedes.
千足虫有很长的进化历史，据推测，1844年在热尔韦发现的最古老的布兰维尔双足虫化石来自志留纪，而第一个确定的化石记录来自泥盆纪沉积物。双足动物的系统发育尚未完全解决，特别是化石代表。与此同时，早在古生代，千足虫就已经表现出相当大的形态多样性，想必也是生态多样性。本文描述了荷兰威斯特伐利亚甲纲石炭纪千足虫的一个新种，Lauravolsella willemeni n. gen.， n. sp.，可能是Archipolypoda Scudder的代表(†Archipolypoda Scudder, 1882)。该物种是基于一个单一的标本，保存了部分和对应的标本，两者都显示了三维保存。标本有异常长的土晶，在正常的生活位置覆盖了大部分的以下部分。这些长牙体在进行防御招募时可能是有益的。在现存的千足虫中，通常通过胸骨之间较软的区域，允许一定程度的腹侧压迫，来促进吸收。在新的化石中，硬化的胸骨骨占据了节段腹侧的整个长度，不允许任何类型的压缩。因此，新化石为登记过程中的机械挑战提供了另一种解决方案，并增加了石炭纪千足虫的形态多样性。

Microremains of fungi from Neogene deposits from the Gray Fossil Site (Tennessee, United States) and the Bełchatów Lignite Mine (Poland), similar to the enigmatic fossil-species Kutchiathyrites eccentricus R.K. Kar, 1979, were reconsidered as representatives of the modern mitosporic genus Mycoenterolobium Goos, 1970. A new combination, Mycoenterolobium eccentricum (R.K. Kar) G. Worobiec, n. comb., is proposed. The geographical and stratigraphical range and ecology of the fossil and modern Mycoenterolobium species are discussed. Investigated remains of Mycoenterolobium eccentricum (R.K. Kar) G. Worobiec, n. comb. document the first fossil record of this fungus from both Northern America and Europe, while the Bełchatów mine represents the northernmost known fossil and modern occurrence of the Mycoenterolobium genus. Both modern and fossil species of Mycoenterolobium seem to prefer warm (tropical to warm temperate), usually humid climates. They are associated with plant debris (mainly wood) decaying in a damp or aquatic environment. Mycoenterolobium eccentricum (R.K. Kar) G. Worobiec, n. comb. is suggested to be used as a non-pollen palynomorph proxy for palaeoclimatic and palaeoenvironmental reconstructions.

Kar, 1979相似，被重新认为是现代有丝孢子真菌属(Mycoenterolobium Goos, 1970)的代表。一个新组合，Mycoenterolobium eccentricum (R.K. Kar) G. Worobiec, n. comb.。，建议。讨论了古真菌肠菌属和现代真菌肠菌属的地理、地层范围和生态学。离心分枝肠杆菌(R.K. Kar) G. Worobiec, n. comb.。在北美和欧洲都发现了这种真菌的第一个化石记录，而Bełchatów矿则代表了最北的已知化石和真菌属的现代出现。现代和化石种的分枝杆菌似乎更喜欢温暖(热带到暖温带)，通常是潮湿的气候。它们与植物残骸(主要是木材)在潮湿或水生环境中腐烂有关。偏心肠杆菌(R.K. Kar) G.
