Stylets are specialized for piercing, liquefying and sucking the tissues of their prey. The shape, length and thickness of the stylets can differ immensely among larvae of different in-groups of Neuroptera. In addition, the stylets may possess a single tooth or multiple teeth of various sizes and positions, or may totally lack teeth. The larvae of split-footed lacewings (Nymphidae) are often characterized by a single tooth on each stylet and a relatively wide head capsule. The tooth in known larvae is arranged in the plane of movement of the stylet itself, as also often seen in other lacewing larvae. Here we describe and analyse a new type of fossil representatives of Nymphidae from about 100-million-year-old Kachin Myanmar amber. The new fossil type has a special morphology with prominent lateral processes on the head capsule and a single prominent tooth per stylet. The fossil type differs from all the other known larvae of Nymphidae by the arrangement of the tooth: it extends outside of the plane of movement of the stylets. Similar arrangements of teeth or spines outside of the plane of movement also occur in some raptorial appendages of other representatives of Euarthropoda, where they form a grasping basket. We discuss the implications of this unusual fossil type, concerning its functional morphology and ecology. •","PeriodicalId":9332,"journal":{"name":"Bulletin of Geosciences","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46681547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The late Katian fauna includes the trinucleid Auritolithus corbetti gen. et sp. nov., the calymenids Salterocoryphe ? bailliei sp. nov. and Vietnamia hyron sp. nov., and limited material of the lichid Amphilichas ? and two indeterminate asaphids. Auritolithus , characterized by the markedly subpentagonal outline of the cephalon, cannot be assigned to any of the existing trinucleid subfamilies but seems closely related to forms occurring in the Upper Ordovician of the Precordillera Basin of Argentina. Salterocoryphe ? bailliei , the first record of a member of the Colpocoryphinae from Australia, is considerably younger stratigraphically than other occurrences of that genus in the middle to upper Darriwilian of France and the Iberian Peninsula. The Rhuddanian fauna from the Arndell Sandstone includes the illaenid Pepodes agrestis gen. et sp. nov., the scutelluid Japonoscutellum senectum sp. nov., the brachymetopid Niuchangella agastor sp. nov., the encrinurids Arndellaspis oryxis gen. et sp. nov. and Cromus ?, the calymenid Gravicalymene clarkei sp. nov. and the homalonotid Brongniartella calveri sp. nov. Niuchangella is accepted as a senior synonym of Radnoria . Arndellaspis is not closely related to other members of the Encrinurinae from Australia but shares unique derived characters of the pygidium with Encrinurus ( s.s. ) and Wallacia , occurring in Laurentia, Avalonia and Baltica, and Arndellaspis may share common ancestry with Encrinurus . The commonly broadly interpreted Gravicalymene is revised and restricted to a smaller number of closely related species from the Darriwilian to middle Telychian. The faunal affinities of the trilobites suggest links with terranes that lay along the north-western margin of Gondwana and with South America in the Late Ordovician, and with South China and possibly Laurentia in the early Silurian.","PeriodicalId":9332,"journal":{"name":"Bulletin of Geosciences","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42704564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In northern Kerman Province, the Ordovician sedimentary interval is known as the Katkoyeh Formation, which encompasses ~ 70–300 m of siliciclastic rocks with scarce carbonate and thick pyroclastic beds in its upper part. Previous studies provided several ages for the Katkoyeh Formation, puzzled by the limited number of palaeontological studies, mostly based on spot samples, the presence of regional important stratigraphic gaps, and the inherent structural complexity of the area. In order to adjust the depositional time of the Katkoyeh Formation, a systematic sampling for microfossils was conducted in the Banestan Section, located about 12 km northwest of the city of Zarand, in the vicinity of the Banestan village. Based on the occurrence of important biostratigraphic species, we recorded three conodont intervals in ascending order in the Katkoyeh Formation, namely the Rossodus manitouensis/ Paltodus deltifer Concurrent Range Zone (Tremadocian, Lower Ordovician), the Juanognathus variabilis Range Zone (Floian, Lower Ordovician), and the Icriodella superba Range Zone (Katian–?Hirnantian, Upper Ordovician). The conodont biostratigraphy is discussed and analysed, improving the Ordovician intrabasinal correlation of Iran as well as correlation with distant palaeobiogeographic domains. The Upper Ordovician conodont assemblage is accompanied by two new species of ostracods: Satiellina zarandensis sp. nov. and Ceratopsis persicus sp. nov., both suggesting palaeobiogeographical affinities mainly with Gondwana and peri-Gondwanan regions. •","PeriodicalId":9332,"journal":{"name":"Bulletin of Geosciences","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44759083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
