In the present work, we report the discovery of several carapaces of Zanthopsis sp. from the Lower Eocene of Central Iran, which represent the easternmost record of the genus. In addition, we discuss on the similarities of the different species and/or morphotypes of the genus, and conclude that the European species could be ascribed to the “Zanthopsis leachii complex”, until future works determine the validity of the species therein contained. In this sense, Zanthopsis jacobi Van Straelen, 1924, in agreement with Artal and Vía (1988), is herein considered a junior synonymous of Z. dufouri (H. Milne Edwards in d’Archiac, 1850). The presence of Zanthopsis in the lower Eocene of Iran suggests homogeneity of the brachyuran fauna on both sides of the Tethys Realm.
在本工作中,我们报告了在伊朗中部下始新世发现的几具Zanthopsis属的甲壳,它们代表了该属的最东端记录。此外,我们讨论了该属的不同物种和/或形态的相似性,并得出结论,欧洲物种可以归因于“Zanthopsis leachii complex”,直到未来的工作确定其中包含的物种的有效性。在这个意义上,Zanthopsis jacobi Van Straelen, 1924,与Artal和Vía(1988)一致,在这里被认为是Z. dufouri的低级同义(H. Milne Edwards In d 'Archiac, 1850)。伊朗始新世下部花萼的存在表明,在特提斯王国两侧的短叶兰动物群具有同质性。

Alcide d’Orbigny made his mark in the history of French Palaeontology by becoming, in 1853, the first holder of the chair of Palaeontology at the Museum of Natural History, Paris. His work on foraminifera made him one of the pioneers of Micropalaeontology. Today, his original collection of foraminifera, bought by the Museum after his death, represents one of the most prestigious collections of the institution. However, for more than a century, it had been relegated to the reserves and to the good will of a few enthusiasts, while the priority of research study was given to the large vertebrate fossils. It survived the conflicts that affected the Palaeontology department, and was moved in response to construction works, wars and natural accidents such as the great flood of 1910. These different events, combined with inappropriate storage conditions, probably caused the fragility of the specimens. In order to better understand this phenomenon, known as Byne's decay, research has been undertaken to reconstruct the various storage points of the collection from its acquisition to the present day. This article aims to demonstrate the close link between the Foraminifera Collection and the history of the chair of Palaeontology, through evidence drawn from the archives of the Palaeontology laboratory and the Museum of Natural History.

Shurabia taewani sp. nov., is the first representative of the reculid family Geinitziidae described from the Upper Triassic of South Korea. The preservation of numerous wing venation characters on this new fossil allows for its placement in the genus Geinitzia and a deep comparison with other genera of Geinitziidae. This discovery suggests that the insect paleofauna of the Amisan Formation is rich and needs to be further investigated. Shurabia taewani sp. nov. differs from the other species currently included in the genus, inter alia, because its vein ScP ends near wing mid-length, its fork of M is at the same level as the fork of R, its RP has five branches, its MA four branches, its MP two branches, and its vein m-cua ‘M5′ originates from the stem of M and ends into CuA.

The Moroccan Anti-Atlas belt preserves an exceptional record of an Ediacaran microbial biosphere. The Amane Tazgart Formation of the Ouarzazate Group corresponds to an Ediacaran volcanic alkaline lake depositional system (ca. 571 Ma) where microbial buildups accreted in an extreme environment. These microbial accumulations are exceptional not only for their diverse range of extreme conditions but also for their significance in understanding the early biosphere and earth's habitability. A description of these buildups provides insights into their Spatio-temporal distribution. The lower part consists of thrombolitic limestones, usually displaying irregular to patchy mesoclots, associated with composite and stromatolitic buildups. The upper part dominated by clastic stromatolites exhibits a variety of morphotypes ranging vertically from planar wrinkly laminated to large domes. The transitional morphotypes are made of linked and vertically oriented or inclined columns, grading upward to cone-shaped domes. The increase in laminated fabrics and the decrease in clotted fabrics toward the top of the section indicate that environmental conditions were likely suitable for coexisting both fabrics during microbial carbonate accretion. The demise of carbonate production at the late stage coincides with riverine input of clastic sediments, subsequently followed during low sediment input by growth of siliciclastic stromatolites.

The Aït Athmane section is located in the eastern part of the central High Atlas, about 20 km north of Errachidia. Its Toarcian series consists of silty marl and silty marly limestone. Its lower part, of early (Levisoni Zone?) to middle Toarcian (Bifrons and Gradata? Zones) age, is rich in brachiopods (rhynchonellides and terebratulides). Its upper part, of late Toarcian age, is rich in terebratulids. Among eighteen reported brachiopod taxa, six are new for the central High Atlas. Their specific assemblages and stratigraphic distributions are similar to those of the Toarcian brachiopods reported from several basins of northern and southern margins of the Tethys and the Subboreal domain, particularly of western France.

The lower Cenomanian strata from the Batna region (NE Algeria) constitute the richest and most diversified deposits in terms of macro-invertebrates, mainly dominated by bivalves both in terms of specimens and taxa. Among them, Crassatellidae are restricted to the lower Cenomanian stratigraphical levels. They are represented by the single species Crassatella baudeti. The species is easily distinguished by its flattened boat anchor shape and quite strong commarginal lamellae, and is very abundant. It is present in levels ranging from Sharpeiceras schlueteri Subzone to Cunningtoniceras inerme Zone. The species is, therefore, a good marker of the last levels of the lower Cenomanian and the beginning of the midlle Cenomanian. A precise palaeontological description and an environmental discussion were conducted. Thus, Cr. baudeti would be indicative of a shallow environment, with cold but calm waters, normal salinity and moderately soft substrate. Recorded exclusively from the Cenomanian of a few Tethys localities, the exclusive presence of Cr. baudeti reflects a specific thermal gradient and climatic zonation.

Ammonitoceras Dumas, 1876 is a genus of heteromorph ammonites characterized by the presence of a peculiar ontogenetic stage in its inner whorls: the Ammonitoceras stage. But in spite of its wide paleogeographic and biostratigraphic extension throughout the Aptian (Lower Cretaceous), this genus remains poorly known. In the present work we study specimens of Ammonitoceras from the lower Aptian Deshayesites multicostatus (Deshayesites deshayesi Zone) to Dufrenoyia furcata (Dufrenoyia furcata Zone) subzones of the Les Ferres Aptian Basin (southeastern France). The results are as follows: (1) representatives of Ammonitoceras from this area are regarded dimorphic with criocone macroconchs and ancylocone microconchs, (2) their ontogenetic sequence is described, (3) their intraspecific variability is significant and concerns the adult size and the duration of the ontogenetic stages, especially the Ammonitoceras stage, (4) two species are recognized: the earlier Ammonitoceras ucetiae Dumas, 1876, characterized by a brief Ammonitoceras stage on average, and the latter Ammonitoceras lahuseni (Sinzow, 1906), characterized by a longer Ammonitoceras stage on average. The sample of the Deshayesites grandis Subzone (Deshayesites deshayesi Zone) is composed of specimens too fragmentary to be identified at species level.

A new genus and species of anaxyelid wasp is described and figured from the mid-Cretaceous Burmese amber as Curvitexis kopylovi gen. et sp. nov. The placement of this new genus within the Anaxyelidae is corroborated by its wing venation and the configuration of its mesosoma. This new genus differs from all other Syntexinae from the mid-Cretaceous Burmese amber biota, inter alia, owing to its forewing with the vein 1Rs curved and longer than 1M, the crossvein 1r-rs absent, the vein 2Rs + M present; the hind wing with the abscissa 2M + Cu present, the vein m-cu absent, and the cell r closed. The recently described Paraxiphydria resinata Gao et al., 2022 is transferred to Anaxyelidae: Syntexinae, and the subfamily Paraxiphydriinae Gao et al., 2022 is synonymized under Syntexinae.

The metriorhynchids from the Jurassic of Normandy have been known since the 19th century. However, the remains studied until now have rarely been found in anatomical connection. The acquisition of specimen MPV 2010.3.610 that was found in the Callovian of Vaches-Noires cliffs by the Paleospace Museum in 2010, allowed the first description of the most complete Metriorhynchidae from this locality so far. The analysis of this Metriorhynchidae raises questions about the taxonomic value of several criteria currently used to distinguish between the different Callovian and Oxfordian species. The study of the cranial and postcranial elements shows that this specimen presents diagnostic criteria of different Metriorhynchidae such as the shape of the prefrontals, the mandible, the palato-maxillary suture, the atlas/axis, the cervical vertebrae as well as the extension of the jugal bone and the morphology of the teeth. A discussion highlights the limitations of the current classification of Metriorhynchidae.

A discussion highlights the limitations of the current classification of Metriorhynchidae.</p></div>","PeriodicalId":50780,"journal":{"name":"Annales de Paleontologie","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46455831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the ammonite collection from the Neuquén and Mendoza provinces made by G. Bodenbender, stands Aspidocerasbodenbenderi Behrendsen. This rare aspidoceratid is assigned to the lower Alternans Zone because of the associated Parodontoceras calistoides (Behrendsen), and can be most likely attributed to the recently established genus Hypowaagenia Schweigert & Schlampp.
