In this paper, five new pollen genera and twenty new pollen species of angiospermae from the Late Cretaceous of a certain basin in central China are described. Four new organ genera and their species include: Morinoipollenites normalis gen. et sp. nov., Morinoipollenites minor gen. et sp. nov., Morinoipollenites polyprojectus gen. et sp. nov., Morinoipollenites rhombiformis gen. et sp. nov., Jianghanpollis ringens gen. et sp. nov., Jianghanpollis, mikros gen. et sp. nov., Jianghanpollis radiatus gen. et sp. nov., Jianghanpollis sayangensis gen. et sp. nov., Jianghanpollis arciformis gen. et sp. nov., Myoporumpollonites variabilis gen. et sp. nov., Myoporumpollenites striatus gen. et sp. nov., Lythraites giganteus Yu, Guo et Mao gen. et sp. nov. Lythraites clavatus sp. nov., Lythraites dilutus sp. nov., Lythraites magnus sp. nov., Lythraites varrustriatus sp. nov., Lythraites pachyrrhachis sp. nov.; the new-form genus and its species are: Crassimarginpollenites reticulatus gen. et sp. nov., Crassimerginpollenites mirus gen. et sp. nov., Crassimarginpollenites psilatus gen. et sp. nov. The new pollen genera and their species described herein have been compared in some details with recent pollens and considered their affinity with such recent families as Dipsacaceae, Myoporaceae, Apocynaceae and Lythraceae. According to the age of the pollen-bearing strata, a preliminary discussion is made regarding to the taxonomy of the recent plants families with which our new described pollens are related. Hence, this study may provide some mieropalaeobotanical information for deciphering 'the phylogeny of these plants.  相似文献

Neoselachian sharks and rays from the British Bathonian (Middle Jurassic)   总被引:2,自引:1,他引:1  
Extensive sampling of Bathonian sediments from localities across southern and central England has produced over 8000 neoselachian teeth. These comprise diverse faunas, with over 25 species being represented in total, most of them previously undescribed. Seventeen new species and seven new genera are named: Palaeoscyllium tenuidens sp. nov., Praeproscyllium oxoniensis gen. et sp. nov., Eypea leesi gen. et sp. nov., Proheterodontus sylvestris gen. et sp. nov., Paracestracion bellis sp. nov., Palaeobrachaelurus mussetti sp. nov., Heterophorcynus microdon gen. et sp. nov., Dorsetoscyllium terraefullonicum gen. et sp. nov., Ornatoscyllium freemani gen. et sp. nov., Pseudonotidanus semirugosus gen. et sp. nov., Synechodus duffini sp. nov., Protospinax magnus sp. nov., P. bilobatus sp. nov., P. carvalhoi sp. nov., Belemnobatis kermacki sp. nov., B. stahli sp. nov. and Spathobatis delsatei sp. nov. In addition, a new family, the Pseudonotidanidae fam. nov., is defined and the status of Paranotidanus Ward and Thies, 1987, Hybodus levis Woodward, 1889 and Breviacanthus brevis (Phillips, 1871) are discussed. These taxa show strong facies specificity, with different species being restricted to different palaeoenvironments.  相似文献

Until now, only two Psychodoidea were known from Lebanese amber. We describe two new genera and species of Phlebotomidae ( Mesophlebotomites hennigi gen. et sp. nov., Libanophlebotomus lutfallahi gen. et sp. nov.) and four new genera with six new species of Psychodidae ( Paleopsychoda solignaci gen. et sp. nov., Paleopsychoda jacquelinae sp. nov., Protopsychoda nadiae gen. et sp. nov., Protopsychoda hammanaensis sp. nov., Libanopsychoda abillamai gen. et sp. nov., Cretapsychoda inexpectata gen. et sp. nov.) from the Lower Cretaceous amber of Hammana/Mdeirij, Lebanon. These fossils are included in a phylogenetic analysis of the subfamilies of Psychodoidea. This superfamily was probably as diverse in the Early Cretaceous as now.  相似文献

The rich fauna of Late Devonian (Late Frasnian) siliceous sponges from the Holy Cross Mountains, Poland is composed of 15 species and 11 genera. Both astylospongid demosponges (lithistids) and hexactinosan hexactinellids are present. The following new genera and/or species are proposed: D regulara Rigby and Pisera sp. nov., Jazwicella media Rigby and Pisera gen. et sp. nov., Astyloscyphia irregularia Rigby and Pisera gen. et sp. nov., A. turbinata Rigby and Pisera gen. et sp. nov., Astylotuba modica Rigby and Pisera gen. et sp. nov., Paleoregulara cupula Rigby and Pisera gen. et sp. nov., Paleoramospongia bifurcata Rigby and Pisera gen. et sp. nov., Cordiospongia conica Rigby and Pisera gen. et sp. nov., Paleocraticularia elongata Rigby and Pisera gen. et sp. nov., P gigantia Rigby and Pisera gen. et sp. nov., Polonospongiadevonica Rigby and Pisera gen. et sp. nov., P fistulata Rigby and Pisera gen. et sp. nov., Urnospongia modica Rigby and Pisera gen. et sp. nov., and Conicospongia annulata Rigby and Pisera gen. et sp. nov. The investigated fauna contains the youngest astylospongiids known and the oldest well-preserved, and most diversified Palaeozoic hexactinosans. The sponge fauna constituted a significant element of a brachiopod-coral-sponge assemblage that inhabited a deep slope of the local Dyminy Reef structure, during its final phase of growth, in a clearly hemipelagic setting. This fauna is limited to the intrashelf depression within an incipiently drowned carbonate platform.  相似文献

Abstract  A new family, Grammolingiidae of fossil lacewings is erected, of which 3 new genera and 6 new species are described and illustrated: Grammolingia boi . gen. nov. et sp. nov., Lithlingia rhra gen. nov. et sp. nov., Litholingia eumopha gen. nov. et sp. nov. and Litholingiu polychotom gen. nov. et sp. nov., Leptolingia jurassica gen. nov. et sp. nov. and Leptolingia tianyiensis gen. noc. et sp. nov. A key to genera within this new family is provided. All specimens described were collected from the Middle Jurassic Jiulongshan Formation of Eastern Inner Mongolia, China. The present discovery demonstrates that present knowledge of the Jurassic Neuropetra fauna remains very poor. The fossil specimens are deposited in Yizhou Fossil Museum and Department of Biology, Capital Normal University, respectively.  相似文献

Seven new species of Paramunnidae from the Magellan Strait are described, two of which are placed in new genera: Paramunna magellanensis sp. nov., P. menziesi sp. nov., P. parasimplex sp. nov., P. patagoniensis sp. nov., Allorostrata ovalis gen. et sp. nov., Austrosignum dentatum sp. nov., and Magellianira serrata gen. et. sp. nov. Four known paramunnid species from the same location are redescribed: Parammunna integra, P. simplex, P. subtriangulata and Munnogonium tillerae . While investigating the genus Paramunna , two species of this group, Acutomunna foliacea (Chardy, 1975) gen. nov. and Paramunna foresti Carvacho , 1977 were removed, which involved the erection of a new genus. The allocation of P. foresti remains uncertain. Some diagnostic characters of the Paramunnidae and a key to the Magellanic species of Paramunna are presented.  相似文献

Abstract:  Twenty species of bivalves (14 new) and 14 genera (six new) are described from two localities in the Silurian, upper Telychian, Oktavites spiralis Biozone of Spain: Cardavia cathleenae gen. et sp. nov., C. hafi sp. nov . , C. stefani sp. nov.; Copenychia franta gen. et sp. nov., C. pristina sp. nov.; Stolidotus marco sp. nov.; Telycardia malinka gen. et sp. nov.; Silurinka vetula gen. et sp. nov.; Bolsopteria lentilka gen. et sp. nov.; Nennapteria ibericola gen. et sp. nov., N. ollicula sp. nov.; Actinopteria dakryodes sp. nov., A. isabelae sp. nov. and Dceruska hispanica sp. nov. They comprise two closely related communities, the Copenychia-Cardavia-Actinopteria Community and the Dceruska-Copenychia-Stolidotus Community, which belong to the Snoopyia Community Group. The occurrence of Dceruska Barrande, 1881, Dualina Barrande, 1881, Patrocardia Barrande, 1881, Silurinka , gen. nov., Slava Barrande, 1881 and Stolidotus Hede, 1915 in the Telychian of the Central Iberian Domain, Spain, supports palaeogeographical relationships with other Lower Silurian regions of north Gondwanan and Perunican Europe: the Carnic Alps (Austria), the Montagne Noire (France), Sardinia (Italy) and the Prague Basin (Bohemia), and also to Avalonia: the Welsh Borderland (Great Britain) and Baltica–Skåne (Sweden). These genera together with the new genera Cardavia, Copenychia (the earliest known representatives of the Silurian family Cardiolidae), Telycardia (the oldest known representative of the family Praecardiidae) and Silurinka belong to a Bohemian type of bivalve. Bolsopteria lentilka is closely related to Bolsopteria elliptica (Hind, 1910) from the Aeronian (middle Llandovery) of Scotland.  相似文献

Abstract:  A diverse fauna of three-dimensionally preserved sponges is described from nearshore volcanogenic sandstones near Llandrindod, Mid-Wales. The fauna was preserved through early marginal silicification, in rare examples with silicification of soft tissue, and includes aspicular and spicular demosponges, hexactinellids, and a heteractinid. The fauna is largely endemic, with the following new species, genera and families erected: Onerosiconcha gregalia gen. et sp. nov., Ordinisabulo quadragintaforma gen. et sp. nov., Miritubus erinaceus gen. et sp. nov., Vadosifistula milvus gen. et sp. nov., Polycornua trescelestus gen. et sp. nov. (Pseudolanciculidae fam. nov.), P. entropus sp. nov., Palaeocallyoides improbabilis gen. et sp. nov., Reticulicymbalum tres gen. et sp. nov., Triactinella rigbyi gen. et sp. nov. (Triactinellidae, fam. nov.), Spissiparies minuta gen. nov., Brevicirrus arenaceus gen. et sp. nov., Pyritonema scopula sp. nov. (Pyritonemidae, fam. nov.) and Microastraeum tenuis gen. et sp. nov. In addition, Pseudolancicula Webby and Trotter is recorded outside Australia for the first time, although only as isolated spicules. The environment represented by this fauna has not previously yielded articulated sponges, and thus the apparent endemism may be misleading.  相似文献

Abstract:  Three new genera including four new species of the bivalve family Mysidiellidae are described from late middle to early late Anisian (Middle Triassic) deposits of Qingyan, Guizhou Province, south-west China. The new taxa Leidapoconcha gigantea gen. et sp. nov., Waijiaoella elegans gen. et sp. nov., Waijiaoella speciosa gen. et sp. nov. and Qingyaniola mirabilis gen. et sp. nov. significantly increase the known taxonomic diversity within the Mysidiellidae. These findings suggest a somewhat endemic evolutionary development within this small bivalve family during the Middle Triassic in south-west China.  相似文献
