The understanding of the taxonomy, diversity, and evolutionary patterns of caviids in northwestern Argentina is still in the process of development. This paper presents new insights into the systematic and evolution of Orthomyctera andina (Rovereto, 1914), one of the most abundant species within Caviidae Fischer de Waldheim, 1817, in the fossil record of this region. A comprehensive anatomical description and taxonomic review of Orthomyctera andina in a phylogenetic context is provided. Moreover, it includes a redescription of the type specimen of Orthomyctera rigens (Ameghino, 1888). The taxonomical results confirm that O. andina belongs to a different genus: Orocavia (Kraglievich, 1932). The phylogenetic analysis further confirms the placement of both species within Caviinae Fischer de Waldheim, 1817. Orthomyctera andina is the sister taxon of the clade that includes Microcavia Gervais & Ameghino, 1880, Dolicavia Ameghino, 1916, Neocavia Kraglievich, 1932, and Orthomyctera Ameghino, 1889. It is supported by a combination of plesiomorphic characters (e.g. furrow opposite to hypoflexus/id in molariforms) shared with basal taxa and Dolichotinae Pocock, 1922 and derived characters (such as a terreced palate, external auditory meatus below the occlusal surface , length of p4-m1 shorter than length of m2-m3) shared with Caviinae. This study aims to elucidate the taxonomic status of these poorly known rodents and their relationships within Caviidae. Additionally, it incorporates a biogeographic analysis of caviomorph communities from the late Neogene in Argentina.

The asymmetry observed in rhynchonellid brachiopod shells has been discussed for decades and continues to attract attention. This noteworthy modification of the anterior margin morphology during the ontogeny has evolved several times in rhynchonellids, and seems to reflect a genetic basis. First, we try to clarify the terminology regarding asymmetrical, dissymmetrical and symmetrical shells that has existed since the beginning of the 20th century. The Cretaceous populations observed clearly exhibit antisymmetry (also called random asymmetry). During the Cretaceous, some populations of Cyclothyris McKoy, 1844 include a mixture of truly asymmetrical specimens and others that exhibit an intermediate degree of asymmetry, herein called atypical morphologies. Shapes of specimens coming from two different locations in France were captured using geometric morphometrics. We used the range of different morphologies: 1) to test alternative hypotheses about the ontogeny of asymmetry; 2) to test for the possibility of several morphogroups; and 3) to discuss the determinism of the asymmetry.

The crocodylian dwarf species (i.e., Osteolaemus sp. and Paleosuchus sp.) that live in the equatorial forests all share the peculiarity to present an osteoderm shield which extends beyond the dorsal area that lies between the skull and the caudal crest symphysis. Here we study both the morphology and the microanatomy of the osteoderms in Paleosuchus palpebrosus (Cuvier, 1807), in order to both assess the distribution of bone ornamentation over the osteoderm shield, and to compare the porosity between the dorsal osteoderms with the non-dorsal osteoderms. Since both the ornamental pit excavation and the bone porosity are relevant proxies to the osteoderm blood vessel content, we mapped the distribution of the vascular network within the osteoderm shield in P. palpebrosus. Our results show that both the bone ornamentation and the bone porosity are significantly more pronounced within the dorsal shield osteoderms. Our results suggest that the dorsal osteoderms may be involved in heat transfer via the superficial blood vessels that are located in the ornamental pits if they are artificially exposed to a basking lamp in captive conditions; it is however unlikely to be the case under the canopy of the equatorial forest since the sun exposure is poor. We therefore hypothesize that the dwarf crocodylian extended osteoderm shield mostly consists of a labile calcium resource that would allow to buffer the diet variations which are related to the various equatorial forest niches (i.e., streams, excavated pools, jungle floors, caves).

Marine ostracods of the family Bairdiidae Sars, 1888 have an evolutionary history starting from the Ordovician with an explosive diversification of ornate forms during the Triassic. Representatives of the family are notoriously homeomorphic, which makes their taxonomy a major challenge of modern ostracodology. Their classification has thus been problematic since the 1970s. Here we present the first CT-scan investigation of recent and fossil ornate Bairdiidae valves in order to characterize and evaluate the taxonomic significance of unexploited characters, such as pores and pore canals. Thanks to 3D tomography, we explore the distribution of pores at the surface and the pathway of pore canals within the valve wall of the recent genus Triebelina van den Bold, 1946 and the Triassic genera Nodobairdia Kollmann, 1963 and Mirabairdia Kollmann, 1963. In Triebelina indopacifica van den Bold, 1946, we describe an unexpected system of double pore canals, so far unknown in ostracods. We confirm that pore systems in Triebelina have largely intramural positions. In the Triassic Bairdiidae (Nodobairdia mammilata Kollmann, 1963 and Mirabairdia pernodosa Kollmann, 1963), we recognize simple unrimmed and massively nodular pores as well as marginal pores. Lateral normal pores of the Triassic specimens appear to be mostly in intra-solum positions. Although still exploratory and at the limits of the tomographic resolution, these observations provide new evidence to reject the formerly proposed synonymy of Triassic genera with Triebelina, which obstructed the establishment of a phylogenetic classification.
Bairdiidae Sars, 1888 科海洋梭形纲动物的进化史始于奥陶纪，在三叠纪期间出现了爆炸性的华丽多样化。该科的代表动物具有众所周知的同型性，这使得它们的分类成为现代梭形纲动物学的一大挑战。因此，自 20 世纪 70 年代以来，它们的分类一直是个问题。在这里，我们首次对新近和化石的华丽 Bairdiidae 瓣膜进行了 CT 扫描研究，以描述和评估未利用特征（如孔隙和孔道）在分类学上的意义。借助三维断层成像技术，我们探索了气孔在最近的 Triebelina van den Bold（1946 年）属以及三叠纪的 Nodobairdia Kollmann（1963 年）属和 Mirabairdia Kollmann（1963 年）属瓣膜壁表面的分布情况以及气孔通道的路径。在 Triebelina indopacifica van den Bold（1946 年）中，我们描述了一种意想不到的双孔道系统，这是迄今为止在梭口类动物中未知的。我们证实，Triebelina 的孔道系统主要位于体内。在三叠纪贝类（Nodobairdia mammilata Kollmann, 1963 和 Mirabairdia pernodosa Kollmann, 1963）中，我们发现了简单的无缘孔、大结节孔以及边缘孔。三叠纪标本的侧向正常气孔似乎大多位于溶胶内部。尽管这些观察结果仍是探索性的，而且处于断层扫描分辨率的极限，但它们为否定以前提出的三叠纪属与三叶虫属的同义提供了新的证据，这种同义阻碍了系统发育分类的建立。

The reconstruction process of the skull and skeleton represents a critical step in the study of fossil vertebrates and is often responsible for how the evolutionary history of a taxon is interpreted. It is also an important step in any test of the researcher’s understanding of the anatomy of the fossil. Even so, there is no recognized method for its completion, leaving the actual process to the individual undertaking the investigation. While this is often accomplished in an appropriate manner, there remains extensive room for error. With the onset of cladistic methodology dating back to the 1980s, character state description has become ever more critical in establishing phylogenetic histories, and over a period of 40 years, character state interpretation has often relied on specimen drawings and reconstructions. Based on a career dedicated to the detailed skeletal reconstruction of tetrapods, the content presented here highlights a stepwise approach that is designed to minimize error and increase the value of fossil reconstructions. We describe the skull reconstruction of the Palaeozoic tetrapod Limnoscelis paludis Williston, 1911 and highlight some of the more critical strategies that are necessary to maximize accuracy and hence increase phylogenetic reliability as well as support opportunities for testing anatomical interpretations as well as functional and ultimately behavioural interpretations. We also take the opportunity to highlight the extensive career contributions made to the field of palaeontology by Diane Scott, who for over 40 years has represented the nec plus ultra of fossil preparation, illustration, and reconstruction.

Disarticulated cranial and postcranial bones of a giant salamander (Cryptobranchidae: Andrias sp.) were found in the Upper Pliocene deposits of the Belorechensk locality in the Northern Caucasus. These remains probably belonged to one individual that died during a stage of rapid growth and had a total length of about 90-100 cm. The giant salamander from Belorechensk is among the geologically youngest and the easternmost known in Europe.

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).

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 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.
