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of palynological and macrofloral records in terms of the diversity and vegetation patterns based on the combination of unpublished palynological and freshly published plant fossil records.","PeriodicalId":9332,"journal":{"name":"Bulletin of Geosciences","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2021-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46195457","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}

{"title":"Pseudomyona from the Cambrian of North Greenland (Laurentia) and the early evolution of bivalved molluscs","authors":"J. S. Peel","doi":"10.3140/BULL.GEOSCI.1827","DOIUrl":"https://doi.org/10.3140/BULL.GEOSCI.1827","url":null,"abstract":"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","PeriodicalId":9332,"journal":{"name":"Bulletin of Geosciences","volume":"1 1","pages":"195-215"},"PeriodicalIF":1.9,"publicationDate":"2021-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41638750","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}

Abbassi, H.

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).","PeriodicalId":9332,"journal":{"name":"Bulletin of Geosciences","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2021-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42428135","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}
