The most prominent specimen, a branch with attached lateral branches of higher orders exhibits a distinct anisotomous branching pattern. The very dense wood is composed of tracheids with spaced and partly contiguous uniseriate pits and low rays with one pit per cross-field (mixed protopinaceous type). When foliage is not abraded, Duartenia exhibits coriacious Brachyphyllum-type leaves. Duartenia may be linked to cheirolepid conifers, however, the systematic affinity remains uncertain. The dense wood, characteristic growth pattern and thick, scale like, trichome bearing leaves may be related to ecological conditions that reflect a seasonally dry climate.","PeriodicalId":56273,"journal":{"name":"Palaeontographica Abteilung B-Palaeophytologie Palaeobotany-Palaeophytology","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2012-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75047926","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}

Manchester, Zhekun Zhou","doi":"10.1127/PALB/288/2012/135","DOIUrl":"https://doi.org/10.1127/PALB/288/2012/135","url":null,"abstract":"An emended diagnosis of the extinct cupressoid genus Ditaxocladus S. X. GUO & Z. H. SUN (syn. Fokieniopsis MCIVER & BASINGER) and its three species is proposed based on new collections from the type locality in the Paleocene Wulonggu Formation of Altai in NW China, and other sites from China, SE Russia and western North America. Ditaxocladus planiphyllus S. X. GUO & Z. H. SUN (generitype) is now known from compound racemose fertile branches bearing several opposite pairs of globose to sub-globose seed cones composed of 6-12 decussate peltate scales, in addition to typically oppositely branched sprays. Besides D. planiphyllus, two more species are recognized based on differences in seed cone morphology. D. kivdensis KODRUL in KRASSILOV et al. from the Paleocene of Raichikha in Amur Province, Russia, is distinguished by similar but slender and pendulous cones, while D. catenulatus (W. A. BELL) S. X. GUO, KVACEK, MANCHESTER & Z. K. ZHOU comb. n. (syn. Fokieniopsis catenulata (W. A. BELL) MCIVER & BASINGER and Fokienia ravenscragensis MCIVER & BASINGER) typified by early Paleocene records in North America bears ovoid seed cones with a higher number of cone scales. All three species share the same type of bipinnately and oppositely ramified elongate sprays of cladode-like foliage and pinnately and oppositely arranged seed cones at successive nodes on compound racemose fertile branches. They differ from the living Fokienia, with which they were formerly compared, in oppositely (vs. alternately) branched leafy sprays and oppositely clustered (vs. solitary) seed cones consisting of much fewer cone scales (6-12 vs. 12-18 in Fokienia). Sterile foliage attributed to Ditaxocladus occurs in the Upper Cretaceous to Paleocene of North America, Russia and Paleocene of Spitsbergen. Tracing differentiation of Ditaxocladus populations (or species) over the Northern Hemisphere is hampered by incompleteness of most records based on quite uniform foliage without seed cones. Tetraclinis salicornioides (UNGER) KVACEK from the Eocene to Pliocene of Europe and the Oligocene to Miocene of North America, which shares very similar gross morphology of foliage, differs from Ditaxocladus in the quadrivalvate seed cones and papillate leaf epidermis with undulate anticlinal walls.","PeriodicalId":56273,"journal":{"name":"Palaeontographica Abteilung B-Palaeophytologie Palaeobotany-Palaeophytology","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2012-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84817845","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}

Murthy, Bireswar Chakraborty, Joyti Shanker Roy","doi":"10.1127/PALB/288/2012/41","DOIUrl":"https://doi.org/10.1127/PALB/288/2012/41","url":null,"abstract":"The first stratigraphic borehole EBM-1 in the Muditoli block in the eastern part of the East Bokaro Coalfield, Damodar Basin, is worked out for its spore-pollen content. Gondwana sediments, approximately 1185.00 m thick, comprising green shales, carbonaceous shales, sandstones and coal seams have shown many levels of changing patterns in the spore-pollen groups in the Barren Measures and Barakar formations. Between 1198.30–1095.25 m the specimens are very dark brown and show a distorted exinal surface. The presence of radial monosaccate pollen taxa proves that this stratum is referable to the Talchir Formation, Early Permian. In the up-section, an abundance of Faunipollenites, Scheuringipollenites, Densipollenites and Striatopodocarpites is observed. The relative abundance of these taxa delimits varied levels in the palynosequence of the studied strata from 1086.95 to 13.00 m. Hence, it is inferred that these deposits contain representative palynoassemblages of Early to Late Permian age. The FAD’s of Lundbladispora micro­ conata, Playfordiaspora cancellosa and Arcuatipollenites pellucidus observed at 13.00, 51.50, and 66.70 m depth enhance the end of the Permian level, as these elements are the key species to mark the transition from the Permian into the Lower Triassic. Non-productive strata at varied depths in this complete succession contain an abundance of woody shreds, vegetal matter, and less of palynomorphs, maybe due to the depositional set-up within the sediments during Permian time.","PeriodicalId":56273,"journal":{"name":"Palaeontographica Abteilung B-Palaeophytologie Palaeobotany-Palaeophytology","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2012-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89393721","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}
