Caturoidea is a clade of Mesozoic predatory ray-finned fishes which lived mainly in the Jurassic. The clade has a few records in the earliest Cretaceous and only two in the Triassic. Among the latter, specimen MPCA 632 Caturus sp. doubtfully from continental Early Triassic of Argentina, i.e., outside Europe, was particularly problematic in the light of the known fossil record of the group, which suggested their origin in the Western Tethys. The micropaleontological and geochemical analysis of bulk-rock samples of MPCA 632 allowed us to correct the provenance of the specimen which corresponds to Tithonian marine outcrops of the Vaca Muerta Formation, Neuquén, Argentina. Specimen MPCA 632 is excluded from Caturus and reclassified as Caturoidea sp. MPCA 632 might be a specimen of Catutoichthys olsacheri, the only caturoid known from the Vaca Muerta Formation (Los Catutos Member), but the fossils are not comparable and, thus, this hypothesis needs further study. Additionally, the first-hand study of the type material of the only other alleged Triassic caturoid, Furo insignis, in the Norian of Seefeld, Austria, led to the exclusion of this taxon from the Caturoidea. Consequently, the clade Caturoidea is restricted to the Jurassic–Lowest Cretaceous. After a modest evolution during the Early Jurassic, the group had its initial radiation and westward dispersion across the Hispanic Corridor during the Middle Jurassic and reached its maximal diversity during the Kimmeridgian and Tithonian.

A strongly endemic Upper Pennsylvanian (Kasimovian) rugose coral association consisting of small, mostly non-dissepimented, simple structured and poorly diversified species is studied from the lower member of the Aheimer Formation (Western side of the Gulf of Suez, Egypt). The unit is composed of grey, silty mudstone intercalated with thin, ferruginous, silty dolostone–limestone and calcareous siltstone beds. Ten taxa from four families were identified. Four species of the Antiphyllinae are new; Actinophrentis crassithecata n. sp., Lytvolasma aheimerensis n. sp., L. paraaucta n. sp. and Monophyllum galalaensis n. sp. Besides, Rotiphyllum exile de Groot, 1963 and Bothrophyllum okense Kossovaya, 2001 were identified; four taxa remain in open nomenclature (Lytvolasma cf. canadense, Zaphrentites cf. parallela, Zaphrentites sp. and Ufimia sp.). Rejuvenation, encrustation and bioerosion phenomena are rare. Attachment structures during mature stages are not evident; attachment scars in the apical parts are also rare. Growth patterns and embedding in the muddy deposits indicates that the corals lived as mudstickers in soft substrate. Recrystallization, dolomitization and ferrugination of open pore spaces inside the corals are the most common diagenetic features. The corals from the lower Aheimer Formation represent a typical cyathaxonid fauna that was adapted to high clastic input and turbid waters in a restricted, sheltered, episodically storm-swept inner ramp environment in an embayment of the southern shelf of the Palaeotethys. A time-averaged ramp model shows a regressive development from a mixed carbonate–siliciclastic open inner ramp setting during the Moscovian to the restricted inner ramp of the lower Aheimer Formation (Kasimovian) and following peritidal to fluvial environments of the Gzhelian. General and local palaeoclimatic considerations indicate cooling. Besides relations to northern Spain that root Egypt in the western Palaeotethys, connections existed via the Donets Basin (and the southern Urals) to the Cordilleran–Arctic–Uralian realm which is a cool water province during the Lower and Middle Permian. The Egyptian fauna appears to be a precursor of the anti-tropical cyathaxonid fauna of the latter time slice and also of the Lower Permian cool-water faunas of the east Cimmerian peri-Gondwana terranes.
本文从Aheimer组下部(埃及苏伊西湾西部)研究了一个强烈地方性的上宾夕法尼亚(Kasimovian) rugose珊瑚群，该珊瑚群由小型，大多数非分离，结构简单和多样性差的物种组成。该单元由灰色粉砂质泥岩与薄的铁质粉砂质白云岩-灰岩和钙质粉砂岩夹层组成。鉴定出4科10个分类群。新种有4种;鉴定出放线菌属(Actinophrentis crassithecata n. sp)、Lytvolasma aheimerensis n. sp、L. paraaucta n. sp、Monophyllum galalaensis n. sp.此外，还鉴定出Rotiphyllum exile de Groot, 1963和Bothrophyllum okense Kossovaya, 2001;目前仍有4个分类群(Lytvolasma cf. canada, Zaphrentites cf. parallela, Zaphrentites sp.和ufinia sp.)处于公开命名状态。再生、结壳和生物侵蚀现象罕见。成熟期的依恋结构不明显;根尖部的附着疤痕也很少见。珊瑚在泥质沉积物中的生长模式和嵌入情况表明，珊瑚以泥贴的形式生活在柔软的基质中。珊瑚内部孔洞的再结晶、白云化和铁成矿是最常见的成岩特征。来自下Aheimer组的珊瑚代表了典型的cyathaxonid动物群，它们适应了高碎屑输入和浑浊的水域，在古特提斯南部大陆架的一个有限的、隐蔽的、偶尔被风暴冲刷的内部斜坡环境中。时间平均斜坡模型显示，从莫斯科期的碳酸盐-硅-碎屑混合开放内斜坡环境到下Aheimer组(Kasimovian)的限制内斜坡环境，再到Gzhelian期的潮外环境到河流环境，这是一个倒退的发展过程。一般和局部的古气候因素表明变冷。除了与古特提斯西部的埃及与西班牙北部的关系外，通过顿涅茨盆地(和乌拉尔南部)与科迪勒拉-北极-乌拉尔地区存在联系，这是二叠纪中下时期的一个冷水省。埃及动物群似乎是后一个时间片的反热带cyathaxon类动物群的先驱，也是东西米利亚-冈瓦纳周围地体的下二叠世冷水动物群的先驱。

Abstract In comparison to other cephalopods such as ammonites and belemnites, nautilid shells are relatively rare fossils in Jurassic marine deposits and knowledge of their taxonomy is therefore still patchy. We describe herein a new species of Cenoceras , C. rumelangense , from the early Bajocian Humphriesianum Zone of Luxembourg and Southwest Germany. In Luxembourg, the type material occurs in the ‘Marnes sableuses d’Audun-le-Tiche’ unit, which yields other large-sized cephalopods, such as the largest known belemnite genus, Megateuthis . The new species reaches a remarkable size, with diameters up to 610 mm. Thus, it is amongst the largest known post-Triassic nautilids worldwide, together with Paracenoceras giganteum and Paracenoceras ingens from the Upper Jurassic. Additionally, we discuss some aspects of the taphonomy of these large shells deposited in a shallow marine setting.

Abstract Understanding the diversity of deep-sea fish fauna based on otoliths in the tropical and subtropical West Pacific has been limited, creating a significant knowledge gap regarding regional and temporal variations in deep-sea fish fauna. To address this gap, we collected a total of 122 bulk sediment samples from the Lower Pliocene Gutingkeng Formation in southwestern Taiwan to reconstruct the otolith-based fish fauna. Using planktonic foraminiferal biostratigraphy, we determined the age of the samples to be 5.6 to 3.1 Ma. A total of 8314 otoliths were assigned to 64 different taxa from 33 families, including the discovery of one new genus, Gutingichthys gen. nov., and three new species: Benthosema duanformis sp. nov., Benthosema parafibulatum sp. nov., and Gutingichthys changi sp. nov. Comparisons with other regional otolith-based assemblages highlighted the exceptional diversity of our collection, making it the most diverse fossil fish fauna reported from Taiwan to date. Otolith diversity analysis revealed very few taxa were dominant in the assemblage, particularly the mesopelagic Myctophidae, with a wide variety of minor taxa. The co-occurrence of shallow-water elements suggests episodic storm events as a potential source. The predominance of deep-sea and oceanic fishes indicated an outer-shelf to upper slope environment, resembling the modern outer-shelf and upper slope fish fauna in the region. Our findings suggest an early establishment and persistent presence of the mesopelagic fish community since the Early Pliocene. Further investigations of the Upper Miocene and Pleistocene sections of the Gutingkeng Formation would provide valuable insights into the evolution of deep-sea fish fauna in the area.

Further investigations of the Upper Miocene and Pleistocene sections of the Gutingkeng Formation would provide valuable insights into the evolution of deep-sea fish fauna in the area.","PeriodicalId":56059,"journal":{"name":"Swiss Journal of Palaeontology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135388448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Convergent evolution is a common phenomenon, independently leading to similar morphologies in different evolutionary lineages. Often similar functional demands drive convergent evolution. One example is the independent evolution of grasping structures in different lineages of Euarthropoda, though the exact morphology of these grasping structures varies significantly. In this study, we investigated grasping apparatuses with two movable counteracting structures as well as some related structures, exemplified by the stylets (compound structures of mouthparts) of aphidlion-like larvae (part of Neuroptera or lacewings) and the cerci of immature earwigs (Dermaptera). For the stylets of aphidlion-like larvae, studies have pointed to a significant loss in morphological diversity in the last 100 million years. We used quantitative morphology to evaluate if a similar process has also occurred in the cerci of earwigs. The cerci of extant immature earwigs exhibit two distinct types of morphologies in the modern fauna: elongated cerci divided into several ringlets with a feeler-type function, and pincer-like stout cerci. In some fossil immature earwigs, however, the cerci are generally elongated but undivided and roughly occupy the morphospace between those of the two modern cerci types; hence this fossil cerci morphology appears to have been lost. To some extent, a comparable loss is also found in certain lacewing larvae. Outgroup comparisons suggest that the morphologies no longer present today are in fact not ancestral, but instead specialised, hence their loss is possibly resulting from disruptive evolution in earwigs as well as lacewings. We discuss the possible functions of these specialised grasping structures.
