山东西部肥城煤田晚石炭世鹦鹉螺

记述的鹦鹉螺主要产于太原组煤层顶板的深灰色砂质泥岩，少数产于石灰岩中，共４科７属１４种。其中Ｔａｉｎｏｃｅｒａｔｉｄａｅ科和Ｇｒｙｐｏｃｅｒａｔｉｄａｅ科标本颇为丰富，前一科属种较多，有３属９种。Ｐｌｅｕｒｏｎａｔｉｌｕｓ属曾见于我国北方甘肃、山西、河北等省的上石炭统（尹赞助，１９３３），而Ｔａｉｎｏｃｅｒａｓ，Ｇｚｈｅｌｏｃｅｒａｓ则为华北地区上石炭统首次发现；后一科除我国北方各省已报道的Ｄｏｍａｔｏｃｅｒａｓ外，另建立１新属新种Ｆｅｉｃｈｅｎｇｏｃｅｒａｓｆｏｓｓａｌｕｍｇｅｎ．ｅｔｓｐ．ｎｏｖ．。Ｔｒｉｇｏｎｏｃｅｒａｔｉｄａｅ科和Ｋｏｎｉｎｃｋｉｏｃｅｒａｔｉｄａｅ科在本区上石炭统各发现１属，即Ａｐｈｅｌａｃｅｒａｓ和Ｆｏｏｒｄｉｃｅｒａｓ。从鲁西晚石炭世Ｆｏｏｒｄｉｃｅｒａｓ的发现，表明此属最早应始于晚石炭世，繁盛于二叠纪。晚石炭世本区海水时进时退，在滨海沼泽之后，随之而来的大面积海侵，由于陆缘浅海区阳光充足、盐度正常、藻类极度繁盛，为营游泳生活的鹦鹉螺和底栖生物提供了生存和繁衍的有利条件，故能在生物繁盛、沉积物堆积速度较快的情况下，保存大量完好的生物化石。

黑龙江东部龙爪沟群七虎林组菊石之修定

梁中发和王义刚分别于１９８２年和１９８３年记载了产自黑龙江东部龙爪沟群六虎林组的菊石化石。这些化石标本保存相当差，均为压模标本，当时鉴定计有ＡｒｃｔｏｃｅｐｈａｌｉｔｅｓｐｅｉｄｅｅｎｓｉｓＬｉａｎｇ，ＣａｌｌｉｐｈｙｌｌｏｃｅｒａｓｙｕｎｓｈａｎｅｎｓｅＬｉａｎｇ，ＯｘｙｃｅｒｉｅｓｙｕｎｓｈａｎｅｎｓｉｓＬｉａｎｇ，Ｌｏｂｏｋｏｓｍｏｃｅｒａｓ？ｓｐ．和Ｓｔｅｎｏｃａｄｏｃｅｒａｓｓｐ．（梁中反，１９８２）；Ａｒｃｔｏｃｐｔｈａｌｉｔｅｓ（Ｃｒａｎｏｃｅｐｈａｌｉｔｅｓ）ｈｕｌｉｎｅｎｓｉｓＷａｎｇ，Ｓｔｅｎｏｃａｄｏｃｅｒａｓ？ｓｐ．和Ｇｅｎ．ｅｔｓｐ．ｉｎｄｅｔ（王义刚，１９８３）９种。尽管他们记述菊石的产出地层名称不一，属、种鉴定也不相同，但这些化石确系产自同一层位或相当的层位中，而且都定其产出的层位时代为中佛罗世Ｂａｔｈｏｎｉａｎ期。最近，经重新研究这些化石的原标本后，认为它们应归于Ｋｅｎｎｉｃｏｔｔｉａ，Ｋｏｓｓｍａｔｉｃｅｒａｓ和Ｐｓｅｕｄｏｈａｐｌｏｃｅｒａｓ（或为ｓｉｌｅｓｉｔｉｄ）这几个类型。从这几个菊石类型的地质历程来看。     

PHRAGMOTEUTHIDA (CEPHALOPODA: COLEOIDEA) FROM THE LOWER JURASSIC OF DORSET, ENGLAND

Abstract:  Phragmoteuthida from the Lower Jurassic (Upper Sinemurian) of Dorset, England, are fully described for the first time. Two species are recognized and described: Phragmoteuthis montefiorei (J. Buckman) and P. huxleyi sp. nov. Phragmocones have an apical angle of between 20 and 30 degrees, and relatively few chambers compared with belemnoids. The conotheca is multi-layered. The siphuncle is thick-walled. The pro-ostracum is long and three-lobed as in the Triassic species. Arms are short and bear pairs of slightly curved hooks. Shell and siphuncle structure do not indicate a close relationship with other coleoids.     

Resolving polyphyly within the Endocerida: The Bisonocerida nov., a new order of early palaeozoic nautiloids

Although the Early Palaeozoic cephalopod order Endocerida is generally regarded as monophyletic, alternative views have been expressed. These invoke origins from different lineages within the order Ellesmerocerida. To test these alternatives, various aspects of endocerid morphology (including conch shape, structure of the ectosiphuncle, form of the endosiphuncular deposits, nature of the apical portion of the conch, and distribution of muscle attachment scars) are reviewed and compared with those of potentially related ellesmerocerids, taking regard of their stratigraphical distribution. The taxonomic distribution of endocones and endocone-like structures, combined with the potential for endosiphuncular diaphragms to evolve into endocones, suggests that the presence of endocones cannot be used to diagnose the Endocerida. Two distinct groups of Early Ordovician cephalopods that bear endocones may be recognised. One includes the longiconic Proterocameroceratidae possessing septal necks of variable length, conical and simple endocones, unflated apical portion of the siphuncle, and probable dorsomyarian muscle attachment scars. The second group includes the Piloceratidae, Manchuroceratidae and younger Allotrioceratidae and Najaceratidae. All are characterised by complex endosiphuncular deposits of endocones with conchiolin and calcareous crests, holochoanitic to macrochoanitic septal necks, and probable oncomyarian muscle attachment scars. The earliest pilocerids possess compressed cyrtochoanitic conchs. The coeval appearance of these groups and the similarity of each group to distinct ellesmerocerid taxa suggest that the Endocerida are polyphyletic, and a new order, the Bisonocerida is proposed for this second group.     

Biological response to experimental damage of the phragmocone and siphuncle in Nautilus pompilius Linnaeus

Tsujino, Y & Shigeta, Y. 2012: Biological response to experimental damage of the phragmocone and siphuncle in Nautilus pompilius Linnaeus. Lethaia, Vol. 45, pp. 443–449. Three adult specimens of Nautilus pomplilius Linnaeus from the Philippines were experimented on to estimate the biological response to damage of the phragmocone and siphuncle in this cephalopod mollusc. In addition, the data obtained from the experiments were used for discussion of shell damage in ammonoids and in other extinct cephalopods. Specimen’s phragmocone and siphuncle were perforated and severed artificially, followed by observations in the laboratory tank during periods of 75 and 132 days. For at least 2 or 3 months, all individuals survived after damage to the phragmocone and siphuncle despite loss of neutral buoyancy. Based on our observations after completion of the experiments, the severed adoral remaining part of siphuncle healed by the siphunclar epithelium. In addition, perforation of the phragmocone was partly repaired by shell secretion from the dorsally extending mantle due to subsequent volution of shell growth. Our experiments revealed that damage to the phragmocone and siphuncle in Nautilus was not necessarily a lethal injury. It may be possible that such biological response also applies to extinct ammonoids and nautiloids. In a similar case of extinct ammonoids and nautiloids, damage to their phragmocone and siphuncle may also not have been a lethal injury as with Nautilus. However, some factors leading to death are likely to be dependent on the degree of damage to the phragmocone and siphuncle and influence of hydraulic pressure. □Ammonoids, injury, nautiloids, Nautilus, phragmocone, repair, siphuncle.     

A new pachyosteomorph arthrodire (Pisces: Placodermi) from the Upper Frasnian of the Central Devonian Field,Russia

A new genus and species of pachyosteomorph arthrodire, Omalosteus krutoensis gen. et sp. nov. from shallow-water marine deposits of the Evlanovo Regional Stage (Upper Frasnian, Upper Devonian) of the Central Devonian Field is described. It is tentatively referred to the family Trematosteidae Gross, 1932, which was earlier believed to be endemic to central Europe. The new genus is characterized by a rounded, dorsoventrally compressed cross section of the pectoral region and smooth head shield and postcranial membrane bones. The centrale is elongated, forming a narrow lateral lobe. The praeorbitale, postorbitale, and centrale come in contact in the center of the orbital region. The mediodorsale is wide, its carinal process projects considerably posteriorly. The anterior margin of the anterior ventrolaterale lacks articular facets for the interlaterale.

NEW MYSIDIELLIDAE (BIVALVIA) FROM THE ANISIAN (MIDDLE TRIASSIC) OF QINGYAN, SOUTH-WEST CHINA

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.     

ZOSTEROGRAMMIDA, A NEW ORDER OF MILLIPEDES FROM THE MIDDLE SILURIAN OF SCOTLAND AND THE UPPER CARBONIFEROUS OF EURAMERICA

Abstract:  New Palaeozoic millipedes, Zosterogrammus stichostethus gen. et sp. nov. and Casiogrammus ichthyeros gen. and sp. nov., are described from the Francis Creek Shale Member of the Carbondale Formation (Upper Carboniferous: Pennsylvanian), Mazon Creek, Illinois, and the Hagshaw Hills Inlier (Middle Silurian: Wenlock) of the Midland Valley of Scotland, respectively. These millipedes, together with Purkynia lata Fritsch from the Upper Carboniferous (Westphalian D) of Nýřany, Czech Republic, are placed in the new family Zosterogrammidae within the new order Zosterogrammida. All of these millipedes have very broad terga with a microsculpture consisting of fine transverse terrace lines along the anterior of the terga and oblique terrace lines across the remainder. Zosterogrammida have a trunk-ring architecture consisting of an arched diplotergite, a pair of free ventral diplopleurites and a pair of free ventral sternites, indicating a relatively basal phylogenetic position within Chilognatha. Although the exact phylogenetic position is indeterminate, Zosterogrammus stichostethus has divided sternites, indicating a possible affinity with the Pentazonia. The Hagshaw Hills millipede contributes significantly to the high-rank diversity of Middle Silurian millipedes as all previously described taxa of this age belong to the Archipolypoda.
