Unpublished data resulting from extensive palynological investigation of coal and carbonaceous rocks from more than thirty boreholes, drilled in the Czech sector of the Intra-Sudetic Basin in the second half of the 20 th century, were taxonomically upgraded and analysed for stratigraphic and systematic evaluation. In total 78 genera and 322 miospore and pollen species have been recorded within a radioisotopically constrained ~21 Ma long interval from middle Bashkirian to early Asselian times, i.e. between 318 and 297 Ma. The miospore and pollen assemblages of coal seams are characteristic by the occurrence of stratigraphically important genera ( e.g . Waltzispora , Radiizonates , Tripartites , Kosankeisporites , Gillespieisporites , Cadiospora , Angulisporites , Latensina , Lueckisporites , Spinosporites ) and taxa recorded only within each member with the combination of quantitative data. Five new palynozones of the basin are recognised. All miospore and pollen taxa are divided into categories based on their plant affinity for the comparison of palynological and macrofloral records in terms of the diversity and vegetation patterns based on the combination of unpublished palynological and freshly published plant fossil records.
20世纪下半叶在苏台海内盆地捷克地区钻探的30多个钻孔中,对煤和碳质岩石进行了广泛的孢粉学调查,获得了未公布的数据,这些数据经过分类升级和分析,用于地层和系统评价。从巴什基尔阶中期到阿塞利阶早期,即318到297 Ma之间,在放射性同位素限制的~21 Ma长间隔内,共记录了78属322种小孢子和花粉。煤层的中孢子和花粉组合以地层上重要的属(如Waltzispora、Radiizonates、Tripartites、Kosankeisporites、Gillespeisportes、Cadiospora、Angulisporites、Latesina、Lueckisportes、Spinosporites)的出现为特征,并结合定量数据仅在每个成员内记录分类群。识别出该盆地五个新的坡缕岩带。根据未发表的孢粉学和新发表的植物化石记录的组合,将所有小孢子和花粉分类群根据其植物亲和性划分为类别,以在多样性和植被模式方面比较孢粉学和大花记录。

logical studies of present day bivalves that the Ordo­ vician–Recent members of the Class Bivalvia Linnaeus, 1758 form a monophyletic group, although some relation­ ships within the group remain unresolved (Schneider 2001; Giribet 2008; Plazzi et al. 2011; Sharma et al. 2012, 2013; Bieler et al. 2014; González et al. 2015; Lemer et al. 2019). However, the derivation of Bivalvia from ancestral univalved molluscs and its stem group evolution in the Cambrian remains the subject of speculation (Cope 1997, 2000; Carter et al. 2000, 2011; Fang & Sánchez 2012; Cope & Kříž 2013; Ponder et al. 2020). Two Cambrian bivalved groups are recognised as potential ancestors of Bivalvia but their morphological dissimilarity, together with the general absence of material from the late Cambrian (Furongian), obscures the evolutionary pathway. The Order Fordillida Pojeta, 1975 includes Fordilla Barrande, 1881 (Fig. 1L, N) and Pojetaia Jell, 1980 (Fig. 1M) and its oldest members appeared in the Terreneuvian. The Order Tuarangiida MacKinnon, 1982 contains Tuarangia MacKinnon, 1982 (Fig. 1K) and is described from the late Miaolingian Series (Guzhangian Stage), about 20 Ma later. Tuarangia and the youngest specimens of Pojetaia occur together in the Guzhangian of Denmark (Hinz­Schallreuter 2000). Carter et al. (2011) rationalised the dilemma con­ cerning origin(s) by recognising two major divisions of Class Bivalvia. A Grade Euprotobranchia Nevesskaja, 2009 embraced the two orders Fordillida and Tuarangiida, which were considered in some way likely to be an­ cestral to crown group bivalves, but together did not comprise a monophyletic entity. The grade recognises the dichotomy as stem group bivalves between Fordilla and Pojetaia, and Pseudomyona Runnegar 1983 and Tuarangia, discussed by Runnegar & Pojeta (1992), as a result of which Pseudomyona and Tuarangia were not considered to be Bivalvia. Carter et al. (2006) had considered Tuarangia, Pseudomyona, Watsonella Grabau, 1900 (Fig. 1J) and Anabarella Vostokova, 1962 to form a sister group to Pojetaia and Fordilla and post­Cambrian Bivalvia. A Clade Eubivalvia Carter in Carter et al. (2011) included the post­Cambrian groups traditionally regarded as Bivalvia, but Sharma et al. (2013), Bieler et al. (2014) and others considered Fordilla to be a crown group bivalve. Conversely, Ponder et al. (2020, p. 552) placed
对现代双壳类的逻辑研究表明,1758年林奈双壳类的Ordo - vicii -新近成员形成了一个单系群,尽管该群内的一些关系仍未解决(Schneider 2001;Giribet 2008;Plazzi et al. 2011;Sharma et al. 2012, 2013;Bieler et al. 2014;González et al. 2015;Lemer et al. 2019)。然而,双壳类动物从祖先的单瓣软体动物衍生而来及其在寒武纪的茎群进化仍然是猜测的主题(Cope 1997,2000;Carter et al. 2000, 2011;Fang & Sánchez 2012;Cope & Kříž 2013;Ponder et al. 2020)。两个寒武纪双壳类被认为是双壳类的潜在祖先,但它们形态上的差异,加上普遍缺乏来自晚寒武纪(弗龙纪)的材料,使进化途径变得模糊。1975年的Fordillida Pojeta目包括1881年的Fordilla Barrande(图1L, N)和1980年的Pojetaia Jell(图1M),其最古老的成员出现在Terreneuvian。Tuarangiida MacKinnon, 1982目包含Tuarangia MacKinnon, 1982(图1K),描述于距今约20 Ma的苗岭系晚期(古张期)。Tuarangia和最年轻的Pojetaia一起出现在丹麦的Guzhangian (Hinz-Schallreuter 2000)。Carter等人(2011)通过承认双壳类的两个主要分支来合理化关于起源的困境。A级原鳃亚(Euprotobranchia Nevesskaja), 2009,包括Fordillida和Tuarangiida两个目,它们在某种程度上被认为可能是冠类双壳类的祖先,但一起不构成一个单系实体。该等级将其划分为介于Fordilla和Pojetaia,以及Runnegar和Pojeta(1992)讨论的pseudoomyona Runnegar 1983和Tuarangia之间的茎类双壳类,因此pseudo omyona和Tuarangia不被认为是双壳类。Carter等人(2006)认为Tuarangia, Pseudomyona, Watsonella Grabau, 1900(图1J)和Anabarella Vostokova, 1962构成了Pojetaia和Fordilla以及后寒武纪Bivalvia的姊妹类群。Carter et al.(2011)中的A Clade Eubivalvia Carter包括传统上被认为是双壳类的后寒武纪类群,但Sharma et al.(2013)、Bieler et al.(2014)等人认为Fordilla是冠类双壳类。相反,Ponder et al.

ments of the Iranian and Arabian plates is important for the reconstruction of terrestrial vertebrate distribution in the Afro-Eurasian continents after the subduction of NeoTethys. A part of this importance is related to Cenozoic vertebrate migrations between Afro-Eurasian territories via the Iranian corridor (Hopkins 1959, Steininger et al. 1985, Tchernov 1992, Vrba 1992). The Iranian land bridge, however, may have been limited by natural barriers such as the Zagros Mountains, resulting in endemic realms for some species in Central Iran and the Persian Gulf region. Contrary to the body fossils, vertebrate footprints are autochthonous documents, and new data from Cenozoic vertebrate tracks from Persian Gulf region are an important aid for paleobiogeographic studies of the Middle East. In this context, the aim of this study is twofold: 1) to report a new vertebrate tracksite from the Persian Gulf region and, 2) to evaluate Cenozoic mammal and bird ichnodiversity in the Middle East. The new footprints described in this contribution are from the Agha Jari Formation (late Mio cene–Pliocene) in the northwest of Konar Takhteh, Bandar-e Bushehr area, northern Persian Gulf (Fig. 1).
伊朗和阿拉伯板块的组成对于重建新特提斯俯冲后非洲-欧亚大陆陆生脊椎动物的分布具有重要意义。这种重要性的一部分与新生代脊椎动物经由伊朗走廊在非洲-欧亚大陆之间迁徙有关(Hopkins 1959,Steinger等人1985,Tchernov 1992,Vrba 1992)。然而,伊朗陆桥可能受到扎格罗斯山脉等自然屏障的限制,导致伊朗中部和波斯湾地区的一些物种成为特有物种。与身体化石相反,脊椎动物足迹是本地文献,来自波斯湾地区新生代脊椎动物足迹的新数据是对中东古生物地理学研究的重要帮助。在这种情况下,本研究的目的有两个:1)报告波斯湾地区一个新的脊椎动物踪迹,2)评估中东新生代哺乳动物和鸟类的遗迹多样性。本贡献中描述的新足迹来自波斯湾北部班达尔-布什尔地区Konar Takhteh西北部的Agha Jari组(中新世晚期-上新世)(图1)。

First report of Mid Ordovician (Darriwilian) cephalopods from the Saluk Mountains, southern Kopet-Dagh Region, north-east Iran 伊朗东北部Kopet-Dagh地区南部Saluk山脉中奥陶世(Darriwilian)头足类的首次报告

An assemblage of orthoconic cephalopods collected from oolitic ironstones at the base of the Pelmis Formation (New) of the Saluk Mountains of the southern Kopet-Dahg Region of north-eastern Iran indicate that the base of the Pelmis Formation is likely to be Darriwilian in age. Preservation of the assemblage suggests that it is time averaged and may represent a condensed deposit. The assemblage consists of a single endoceratid, several members of the Orthoceratida as well as an indeterminate taxon. Overall, the assemblage shows affinities with South China and Baltica, as well as with other Middle Ordovician cephalopod assemblages recorded from Iran. • Key words: Ordovician, Darriwilian, Pelmis Formation, Cephalopoda, Orthoceratida, palaeobiogeography, peri-Gondwana, Kopet-Dagh, Iran.
从伊朗东北部Kopet-Dahg地区南部Saluk山脉Pelmis组(New)底部的鲕状铁矿中收集的正锥头足类组合表明,Pelmis组底部的年龄可能为Darriwilian。保存的组合表明,它是时间平均的,可能代表一个浓缩矿床。该组合包括单个内角虫,正角虫的几个成员以及一个不确定的分类群。总体而言,该组合与中国南部和波罗的海以及伊朗记录的其他中奥陶世头足类组合具有相似性。•关键词:奥陶纪,Darriwilian, Pelmis组,头足目,正角目,古生物地理,perio - gondwana, Kopet-Dagh,伊朗
