An anatomically preserved mature stem from the Salamanca Formation (early Paleocene) at Palacio de Los Loros, central Patagonia, Argentina, is described and assigned to Paracacioxylon frenguellii sp. nov. The material was preserved by siliceous permineralization and shows features of the secondary xylem typical of subfamily Mimosoideae. This species represents the oldest record of the genus and of the Leguminosae along the western border of Gondwana, and is the world's second oldest record of Leguminosae wood. The species is characterized by ring-porous to semi-ringporous vessels that are solitary, in multiples of 2-4 and clustered, simple perforation plates, alternate and vestured inter-vessel pitting, homocellular 1-6 seriate rays, tyloses, crystals and diffuse apotracheal, vasicentric paratracheal and confluent axial parenchyma. Paracacioxylon frenguellii has anatomical similarities to Acacia Miller. The presence of Paracacioxylon frenguellii associated with pulvinate leaves suggests that the legumes might have been a component of mesothermal forests developed along the western margin of the Golfo San Jorge Basin during the early Paleocene 2009020179 中国东北部早期被子植物研究近期进展的综述 = A review of recent advances in the study of early angiosperms from northeastern China. ( 英文 ). Sun Ge; Dilcher D L; Zheng Shaolin. Palaeoworld, 2008, 17(3/4): 166-171 The last 10 years (1998–2007) were very productive and important in the study of early angiosperms in northeastern China. The new discoveries of the earliest well-documented records of angiosperms such as Archaefructus, as well as Hyrcantha decussata (= Sinocarpus decussatus), provided fresh knowledge for better understanding the primitive characters of the ancient angiosperms and also their aquatic (or wet) habitat and their herbaceous nature. Some new approaches such as the combination of molecular and morphological characters joined together to place Archaefructus in the angiosperm phylogenetic framework. These fossils demonstrate that we should expect more ancient angiosperms to be found in the pre-Cretaceous which will continue to add important new understanding to the nature of the origin and evolution of the angiosperms. 2009020180 美国堪萨斯白垩纪达科他组与悬铃木科有亲缘关系的中型化石 = Mesofossils with platanaceous affinity from the Dakota Formation (Cretaceous) in Kansas, USA. ( 英文 ). Wang Xin. Palaeoworld, 2008, 17(3/4): 246-252 The Platanaceae holds a basal position in the phylogeny of eudicots and therefore is of great interest to angiosperm systematists. The fossil record of the family is found in strata ranging from the Cretaceous to Recent in America, Europe and Asia. The research on the Platanaceae in the Dakota Formation can be traced back to 19th century; however, mesofossils of reproductive organs of the Platanaceae were never reported in the Midwest of North America before. This paper reports several specimens of Friisicarpus (Platanaceae) from the Dakota Formation in Kansas, USA. It complements the existing fossil records, and provides more information on reproductive biology of the family. The comparison with similar fossils from eastern North America and Europe provides some hints on biostratigraphy of the Cretaceous. 2009020181 新西兰中 - 晚中新世 Dunedin 火山岩群假山毛榉属 = Nothofagus from the Dunedin Volcanic Group (Mid — Late Miocene), New Zealand. ( 英文 ). Pole M. Alcheringa, 1993, 17(1`): 77 - 90 Two species of Nothofagus macrofossils, Nothofagus novaezealandiae and N. pinnata, are redescribed from sediments of late Middle Miocene to early Late Miocene age of the Dunedin Volcanic Province, New Zealand. Examination of leaf architecture and cuticular morphology places N. novaezealandiae in the subgenus Lophozonia (producing menziesiitype pollen), and indicates it was evergreen. N. pinnata was probably also in the subgenus Lophozonia 2009020182 黑龙江嘉荫晚白垩世水生被子植物 = Late Cretaceous Aquatic Angiosperms from Jiayin, Heilongjiang, Northeast China. ( 英文 ). Quan Cheng; Sun Ge. Acta Geologica Sinica, 2008, 82(6): 1133-1140 Three taxa of Late Cretaceous aquatic angiosperms, Queruexia angulata (Lesq.) Krysht., Cobbania corrugata ( Lesq. ) Stockey et al. and Nelumbites cf. extenuinervis Upchurch et al. from Jiayin of Heilongjiang, NE China, are described in detail. Among 58
them, Cobbania and Nelumbites from the Upper Cretaceous in China are reported for the first time. The aquatic angiosperm assemblage of Queruexia-Cobbania- Nelumbites appears to imply a seasonal, warm and moist environment in the Jiayin area during the Santonian-Campanian time. 2009020183 加拿大不列颠哥伦比亚麦卡阿比始新世神秘的花 = The Eocene mystery flower of McAbee, British Columbia. ( 英文 ). Manchester S R; Pigg K B. Canadian Journal of Botany, 2008, 86(9): 1034–1038 A distinctive, extinct type of flower and fruit is described based on coalified compression and impression fossils from the Eocene lake bed deposits of McAbee, British Columbia. Dillhoffia cachensis gen. et sp. nov. has an elongate-ellipsoidal fruit with an epigynous, completely connate funnelform calyx 1.8 – 2.9 cm in diameter, with an unlobed, orbicular margin. The fruit narrows apically into a single style divided into four slightly recurved stigmatic arms. Fruits are pedicellate, borne in globose heads. Stamens, pollen, and internal fruit morphology remain unknown, but the available details of gynoecial and perianth morphology present a suite of characters not encountered in any known extant genus, and the familial affinities remain uncertain. This is noteworthy, because many other elements of the same Eocene flora represent extant genera with clear familial assignments such as Cunninghamia, Ginkgo, Aesculus, Alnus, Betula, Dipteronia, Fagus, Trochodendron, and Ulmus. 古无脊椎动物学综论 2009020184 Rhodes( 希腊 ) 上新世 - 渐新世沉积中钙质微化石 , 介形类 , 和有孔虫生物地层学及与 Vrica ( 意大利 ) 剖面的对比 = Calcareous nannofossil, ostracode and foraminifera biostratigraphy of Plio- Pleistocene deposits, Rhodes (Greece), with a correlation to the Vrica section (Italy). ( 英文 ). Thomsen E; Rasmussen T L; Hastrup A. Journal of Micropalaeontology, 2001, 20(part 2): 143-154 The Kalithea Bay section is situated on the southeastern coast of the island of Rhodes. The section comprises a sedimentary sequence ranging from brackish water gravel and nearshore sand to deep-water clay. The brackish water and nearshore deposits are assigned to the Kritika Formation, while the deep-water deposits are assigned to the Lindos Bay clay. Calcareous nannofossil biostratigraphy shows that the age of the marine sequence is Early Pleistocene. The brackish water sediments cannot be dated with any degree of certainty. The marine deposits are rich in ostracodes and foraminifera and several species, have been recognized, which previously have been used as biostratigraphic markers in the Plio-Pleistocene deposits of Rhodes. Biostratigraphic correlation between the Kalithea Bay section and the Plio- Pleistocene boundary stratotype at Vrica, southern Italy, shows that the ostracodes and foraminifera events generally are diachronous relative to the calcareous nannofossil events. The only exception is the first occurrence of the benthic foraminifera Hyalinea balthica. As calcareous nannofossil events are thought to be virtually synchronous within the Mediterranean region, it is concluded that the diachroneity is due to a relative delay in the appearance of ostracodes and foraminifera at Kalithea, caused by differences in the palaeobathymetric settings between the two sites. 2009020185 热带美国新近纪的 Cupuladriidae 科 II— 巴拿马海峡对岸现生 Discoporella 的系统学 = Neogene Cupuladriidae of Tropical America. II: Taxonomy of Recent Discoporella from opposite sides of the Isthmus of Panama. ( 英文 ). Herrera-Cubilla A; Dick M H; Sanner J; Jackson J B C. Journal of Paleontology, 2008, 82(2): 279-298 15 图版 . We used up to 30 morphological characters to discriminate and describe species of the genus Discoporella based on complete colony specimens collected from both coasts of the Isthmus of Panama. The characters included zooidal characters and colony-level characters such as colony size and basal granule density. Species were classified by a series of multivariate cluster and linear discriminant analyses until the majority of specimens were assigned to their putative species with high confidence. In the first phase of the analyses, the colonies were grouped by ocean (Caribbean versus eastern Pacific), discriminated predominantly by colony size and basal granule density, characters that might reflect ecophenotypic responses to different conditions in primary productivity 59
