A NEW OXFORDIAN PLIOSAURID (PLESIOSAURIA, PLIOSAURIDAE) IN THE CARIBBEAN SEAWAY

Abstract:  A new pliosaurid, Gallardosaurus iturraldei gen nov. et sp. nov., was found in the Viñales area, western Cuba, in sediments of the Jagua Formation, middle–late Oxfordian. This new taxon is characterized by: wide participation of the premaxilla in the outer margin of the external naris; frontal not participating in the orbital margin; postorbital in contact with the jugal and squamosal; presence of anterior pterygoid vacuity; cultriform process of parasphenoid convex and exposed in palatal view; pterygoid flanges high; jaw articulation low relative to tooth row; trihedral teeth in cross-section and with smooth ridges at least in the labial face. A phylogenetic analysis suggests that Gallardosaurus forms a clade with Peloneustes , the most common pliosaurid genus occurring in the Oxford Clay. The Caribbean Seaway was, at least since the Oxfordian, a corridor that permitted the interchange for marine biota between Western Tethys and Eastern Pacific realms. Among vertebrates, bony fish and long-necked plesiosaurs prevailed. However, marine pleurodiran turtles, metriorhynchid crocodilians, ophthalmosaurian ichthyosaurs, and pliosaurids ( G. iturraldei gen. nov. et sp. nov.) have also been found, as well as at least two species of pterosaurs, and one camarasaurian dinosaur. Among these reptiles there were off-shore pelagic forms such as the ichthyosaurs and metriorhynchids, together with the pliosaurid G. iturraldei gen. nov. et sp. nov.; other taxa were presumably less pelagic, such as the pleurodiran turtles and the cryptoclidid plesiosauroids. Gallardosaurus iturraldei gen. nov. et sp. nov. would have played the role of an active predator taking advantage of nectonic fish recorded in the area.     

江西崇义地区上泥盆统节甲类(Arthrodira)的新材料

我国泥盆系鱼化石非常丰富,尤其是下、中泥盆统。但是,上泥盆统鱼化石发现尚少,而且主要是胴甲类化石,节甲类化石则很少发现。潘江（１９６２）在对斯行健已记述的一植物化石 Ｃｈａｎｇｙａｎｏｐｈｙｔｏｎ ｈｏｐｅｉｅｎｓｉｓ Ｓｚｅ重新进行观察时认为,该化石应属于盾皮鱼类,并将其归人瓣甲类 Ｍａｃｒｏｐｔｅｔａｌｉｃｈｔｈｙｉｄａｅ（？）,化石仅包括前腹侧片和胸棘。 Ｄｅｎｉｓｏｎ（１９７８）根据潘江的文章和插图则认为, Ｃｈａｎｇｙａｎｏｐｈｙｔｏｎ ｈｕｐｅｉｅｎｓｉｓ属于原始节甲类或者瓣甲类。王念忠等…     

广西南宁渐新世基于咽齿的鲤亚科一新属

记述了产自广西南宁盆地渐新世早—中期的鲤科鲤亚科一新属种——伍氏南宁鲤(+Nanningocyprinus wui gen.et sp.nov).化石材料包括一些咽喉骨和咽齿.这些咽喉骨和咽齿的以下特征组合明显不同于其他鲤科鱼类:齿式-3·2·1,主行第一枚咽齿大小是第二枚的3～4倍,第二枚咽齿及第二行第一枚咽齿咀嚼面上各仅有一条沟纹,咽骨前角很发育.该属种的发现进一步证明鲤亚科是鲤科中较早的分支,中国南方很有可能是鲤亚科的起源和分化中心.     

A New Genus and Species of Scombrid Fish (Perciformes,Scombroidei, Scombridae) from the Lower Oligocene of the Caucasus

A new genus and species of scombrid fish Caucombrus histiopterygius gen. et sp. nov. is described from the Lower Oligocene (Lower Maikopian, Pshekha regional state) of the north-western Caucasus (Russia) and Abkhazia (rivers Belaya, Pshekha and Gumista). The new taxon differs from the other known Scombridae, both fossil and Recent, by the high and sail-like first dorsal fin. Osteological characters of Caucombrus gen. nov. indicate its relationship with the Spanish mackerels (subfamily Scomberomorinae). It is assumed that either C. histiopterygius gen. et sp. nov. or the related species of Caucombrus gen. nov. inhabited the Mid-Oligocene sea basin in the territory of the Rhine Graben (Germany).     

NEOSELACHIANS FROM THE UPPER CAMPANIAN AND LOWER MAASTRICHTIAN (UPPER CRETACEOUS) OF THE SOUTHERN PYRENEES, NORTHERN SPAIN

Abstract: Bulk sampling of upper Campanian to lower–middle Maastrichtian coastal and lagoonal deposits in five sections of the Tremp Formation in the south‐central Pyrenees yielded numerous neoselachian teeth. The fauna comprises nine taxa of which three species and one genus are new: Hemiscyllium sp., Lamniformes indet., Paratrygonorrhina amblysoda gen. et sp. nov., Coupatezia trempina sp. nov., Coupatezia sp., Coupatezia? sp., Rhombodus ibericus sp. nov. and Igdabatis indicus. The neoselachian fauna is dominated by small nectobenthic rays. This composition resembles assemblages known from the marine Upper Cretaceous, but differs from nearby localities of the Basque‐Cantabrian region and continental selachian associations of the French Pyrenees. The results indicate that Rhombodus might not be a reliable biostratigraphic marker for the Maastrichtian. The faunal composition suggests a shallow trans‐Tethyan connection between Eurasia and India at the end of the Cretaceous Period.

New Aegisthidae (Copepoda: Harpacticoida) from western Pacific cold seeps and hydrothermal vents

Hyperbenthic harpacticoid samples from Japanese hydrothermal vents in the Okinawa Trough and cold seep sites in Sagami Bay were examined and resulted in the discovery of four new species belonging to three new genera of Aegisthidae (Copepoda: Harpacticoida). Females of Nudivorax todai gen. et sp. nov. possess a large area of flexible integument between the cephalosome and the first pedigerous somite which is suggestive of a gorging feeding strategy. Main diagnostic characters separating the new genus from other Aegisthidae are provided by the unusually short caudal rami, the complete lack of intcgumcntal surface lamellae, and the presence in the male of a linear array of pores along the rostral margin which appears to be sensory in function. Scabrantenna yooi gen. et sp. nov. displays several similarities with Aegisthus aculeatus Giesbrecht, 1891 but is highly distinctive in its male morphology which includes extremely atrophied mouthparts and a unique prehensile antenna. Jamstecia terazakii gen. et sp. nov. is only known from a single female caught in the Okinawa Trough. Jamstecia gen. nov. is most closely related to Andromastax Conroy-Dalton & Huys, 1999 but can be distinguished on the basis of the elongate antennules, the antennary morphology, the absence of lateral spinous processes on the cephalosome and swimming legs 2–4, and differences in the mandibular palp and armature of the maxilliped. Andromastax cephaloceratus sp. nov. differs from the type species A. muricatus Conroy-Dalton & Huys, 1998 primarily in the presence of long spinous processes on the cephalosome and the absence of the inner seta on the female P5.     

A new camuropiscid arthrodire (Pisces: Placodermi) from Gogo, Western Australia

A new camuropiscid arthrodire, Latocamurus coulthardi gen. et sp. nov., is described from the Upper Devonian Gogo Formation, Western Australia. Latocamurus , known from two complete specimens, is recognized as a camuropiscid by its narrow, spindle-shaped armour, deep postnasal plates participating in the orbits, preorbital plates which meet mesially, cheek unit firmly sutured to skull roof, posterior check plates tightly interconnected and much reduced, and the robust durophagous dentition. It is characterized by its downturned snout, broad, flat rostral plate, and narrow, deep parasphenoid. It is placed phyletically as the plesiomorphic sister taxon to all other camuropiscids which are more derived in having, inter alia , an anterior lateral plate which anteriorly contacts the anterior ventrolateral plate and pointed rostral plates. The family Camuropiscidae Dennis & Miles 1979b is redefined to incorporate features of the new genus. Camuropiscids and Incisoscutum are closely related by features of the postnasal plate and cheek.     

内蒙古二连盆地早始新世脑木根组上部的奇蹄类(英文)

描述了内蒙古二连盆地脑木根组上部(早始新世伯姆巴期)两种奇蹄类:脊齿貘类的二连明镇貘(新属新种)Minchenoletes erlianensisgen.et sp.nov.和蹄齿犀类的Pataecops parvus。二连明镇貘区别于其他脊齿貘类的特点是:个体小,颊齿齿冠低,齿脊相对不发育,牙齿较横宽(长宽比小),M3相对较长。两种化石分别将脊齿貘科和犀超科的化石记录提前到最早始新世。最新的地层资料表明,明镇貘仅发现于脑木根组上部,相当于伯姆巴期的地层中;施氏貘(Schlosseria)和脊齿貘(Lophialetes)则分别发现于阿山头组和伊尔丁曼哈组。因此,这些化石在生物地层对比和早期奇蹄类演化研究中具有重要价值。依据二连地区的新资料和中亚考察团的野外记录,我们认为蒙古的Pataecops parvus标本可能来自比Kholobolchi动物群大多数种类更低的层位,可能相当于伯姆巴期。

贵州上三叠统一新的海龙(爬行纲:双孔亚纲)

根据头骨和下颌建立了海龙一新属新种——短吻贫齿龙(Miodentosaurus brevis gen.et sp.nov.)。其正型标本是采自贵州三叠纪法郎组的一具骨架(台中自然科学博物馆标本编号NMNS-004727/F003960)。虽然头后骨胳还没有修理,但是几近完好的头骨和下颌显示出许多与众不同的特征,足以确定该标本代表了一新的海龙属种。短吻贫齿龙是个体较大的海龙,其全长超过4 m,头骨背部最长约为33 cm。吻直且极短是其最显著的特征之一。其他主要特征有:前颌骨沿前背中央有一隆嵴;上颌仅前颌骨有6枚圆锥形齿,无上颌骨齿;上颌骨沿前腹侧缘有一沟槽;下颌齿骨齿都集中在前端且至多不超过6枚。依据上述这些特征很易把短吻贫齿龙与其他已知海龙相区别。短吻贫齿龙头骨顶面松果孔大且很前位,头骨腭面的锄骨和翼骨均无齿,它的颈较长(至少可以辨认出13个颈椎)。这些特征显示短吻贫齿龙可能与包括中国安顺龙属(Anshunsaurus)在内的Askeptosauroidea超科有相近的系统关系。

NEW OCTOPODS (CEPHALOPODA: COLEOIDEA) FROM THE LATE CRETACEOUS (UPPER CENOMANIAN) OF HÂKEL AND HÂDJOULA, LEBANON

Abstract:  Three previously unknown octopods are described from Upper Cenomanian limestones of the Hâqel and Hâdjoula localities (Lebanon). Keuppia levante gen. nov., sp. nov., Keuppia hyperbolaris gen. nov,. sp. nov. and Styletoctopus annae gen. nov, . sp. nov. are regarded as the earliest representatives of the Octopoda (= Incirrata). This assumption is mainly based on their medially isolated bipartite gladius vestige. As can be inferred from growth increments, Keuppia gen. nov. can be distinguished from the genus Palaeoctopus by blades that grow forwards along their longitudinal axis. The gladius vestige of Keuppia hyperbolaris sp. nov. differs from that of Keuppia levante sp. nov. in having a more heterogeneous course of growth lines. Based on a pair of widely separated stylets, which closely resemble the rods of modern octopods, Styletoctopus annae gen. nov., sp. nov. is assigned to the Recent family Octopodidae. Peculiar encrustations, which are situated in close association with the gladius vestiges of Keuppia levante sp. nov., Keuppia hyperbolaris sp. nov., and Styletoctopus annae sp. nov. are interpreted as basal fin cartilages. The gladius vestige morphology of Keuppia hyperbolaris sp. nov. and Keuppia levante sp. nov. opens the possibility that both the Octopda and the Cirroctopoda originated from loligosepiid vampyropods instead of teudopseid. The surprising existence of a stylet-like gladius vestige in Styletoctopus annae sp. nov. suggests that the octopod clade branched off much earlier than previously believed. Octopod apomorphies such as the development of stylets, loss of fins and cirri must have been occurred before the Cenomanian.
