Pitted surfaces associated with wall pores are themost important corrasion features. Abrasionsigns such as polished longitudinal and suturalribs have been recognized. Fragmentation iscommon and it is controlled by the shape of thetest rather than by the shell size or thickness.Different types and patterns of dissolution havebeen detected. Micritic infillings have been observedin most of the specimens; nevertheless,sparitic and pyrite cementations are also abundant.Neomorphism includes features such asinversions and recrystallization; pyrite and possiblysilica replacements have been recognized.A great number of the specimens show calciticcrusts that obscure wall surfaces and may preventidentification. Mineralization is representedby sylvite crystals on the surface of some uppermostToarcian and Aalenian foraminiferalshells. Fossil diagenetic distortion is frequentand affects the specimens independently of theirmorphology. Signals of reworking ("resedimentation")are common in the specimens. Two directcriteria for the recognition of reworking("reelaboration") are shown for the first time onthe foraminiferal shells. More research must bedone to discern the history of the foraminiferalassemblages in order to achieve accurate biostratigraphical,paleoecological and paleobiogeographicalinterpretations.2008040194得 克 萨 斯 西 部 Albian 阶 上 部 新 发 现 的 底 栖 有孔 虫 类 = Upper Albian benthic foraminifersnew in west Texas.

Journalof Foraminiferal Research, 2002, 32(1): 43-50 2图 版 .Part of the Lower Cretaceous Gulf Coast carbonateplatform is exposed in west Texas andmapped as the Albian Devils River Formation.Two species of larger benthic foraminifers aredescribed for the first time from this unit thathave biostratigraphic utility. Paracoskinolinacoogani n. sp. was first noted in 1977 but notnamed as a new species. Streptalveolina mexicanaFour-cade, Tardy, and Vila is known fromMexican uppermost Albian/Lower Cenomanianstrata. The Texas occurrence supports the UpperAlbian age of these species. Both species areendemic to the Caribbean Province, but theyappear to be related to species in the MediterraneanProvince, consistent with the known paleogeographicconnections between the regions,although few benthic foraminiferal species areshared.2008040195新 属 Albertinopsis sp.nov. 及 Gavelinellidae科 和 Rosalinidae 科 关 系 的 研 究 = The genusAlbertinopsis, gen. nov. and the relations betweenGavelinellidae and Rosalinidae.

Thenew genus is classified in the Rosalinidae,thereby extending the fossil record of this familyinto the Albian. This extension further complicatesthe attempts to understand the origin anddiversification of the rotaliine foraminifera,which appears to have taken place in the LowerCretaceous.2008040196Conorbina brotzen, 1936 的 系 统 位 置 = Thesystematic position of Conorbina brotzen, 1936.( 英 文 ).

Theobservation of these characters forces a reclassificationof the genus into the Rosalinidae and thelapse into synonymy of the family taxon Conorbinidae.The dissolution of the Conorbinidae andthe extension of the fossil record of theRosalinidae into the Lower Cretaceous furthercomplicates any attempt towards reconstructingthe phylogeny of the rotaline Foraminifera.2008040197Gavelinopsis Hofker, 1951 的 绕 旋 特 性 = Onthe rotaliine nature of Gavelinopsis Hofker, 1951.( 英 文 ).

The uncertaintyof the taxonomic value of this characterincreases the fragility of the suprageneric taxonomicframework of the Rotaliina.2008040198佛 罗 里 达 印 第 安 河 泻 湖 五 年 间 的 有 孔 虫 丰 度变 化 - 一 种 脉 动 模 式 研 究 = Foraminiferal densitiesover five years in the Indian river Lagoon,Florida: a model of pulsating patches.
