Pseudocymopolia anadyomenea, the type-species of the genus, was described by ELLIOTT (1959) from the Maastrichtian of Iraq. Besides the type-locality, it was also recorded from the upper Maastrichtian Tarbur Formation of Iran, from Afghanistan and Tibet. A rich but moderately preserved material is analyzed herein, evidencing the presence of two discrete species: P. anadyomenea and P. acuta n. sp. The new species is characterized by its thallus morphology displaying tapering, keeled segment margins. Besides the morphology, both are also distinguished by biometric parameters such as the outer diameter (D), inner diameter (d), and the d/D ratio. All other Lower Cretaceous species of Pseudocymopolia as well as the Maastrichtian P. anadyomenea have rounded segment margins. Both taxa from the Tarbur Formation occur in inner platform quiet water depositional settings whereas the Lower Cretaceous representatives typically characterize platform margin deposits.
pseudoymopolia anadyomenea是该属的模式种，由ELLIOTT(1959)在伊拉克马斯特里赫特地区描述。除类型地点外，在伊朗上马斯特里赫特塔布尔组、阿富汗和西藏也有记录。本文分析了一个丰富但保存适度的材料，证明了两个独立物种的存在:P. anadyomenea和P. acuta n. sp.新物种的特征是其菌体形态显示锥形，龙骨节边缘。除了形态学外，还可以通过外径(D)、内径(D)和D /D比等生物特征参数来区分两者。所有其他的下白垩世伪种以及马斯特里赫特的P. anadyomenea都有圆形的节缘。Tarbur组的两个分类群都出现在台地内静水沉积环境中，而下白垩统的代表则是台地边缘沉积的典型特征。

A new dasycladalean alga is described as Uteria naghanensis n. sp. from the late Maastrichtian Tarbur Formation of the Zagros Zone, SW Iran. It is a small to medium-sized, rather well calcified species with small articles each bearing one fertile ampulla, alternating with close-set verticils of numerous sterile laterals. Another characteristic is its comparably wide main axis. The genus Uteria Michelin was so far only known from the Paleogene (Danian-Lutetian). The discovery of U. naghanensis n. sp. in inner platform wackestone of the Tarbur Fm. documents the origination of the genus already in the uppermost Cretaceous within an area belonging to the Arabian Plate.

This is the second contribution to the stratigraphic and genetic model of the Pinda Group. The mid-Cretaceous Pinda Group of the Congo basin in the northern Angolan offshore is a transgressive supersequence. Its lower part is made of Bufalo and Pacassa facies that correspond respectively to mixed and calcareous-dolomitic grain-dominated fabrics. Both facies were strongly diagenetically altered, mostly by dolomitic replacement and leaching. Contrary to opinions expressed by other authors that both styles of alteration are early diagenetic phenomena, there is substantial evidence for a burial origin with dolomitic replacement and leaching of calcite having started at depths not less than 150 m and 400 m, respectively.

The purpose of this study is to clarify the problem posed by Triloculina laevigata Orbigny, 1826, nom. nud., described and figured by Fornasini in 1905. An other species, also called Triloculina laevigata was created by Bornemann in 1855 and Orbigny's specific name became invalid. This invalidity was only recently assessed and numerous authors still use the original assignation. Consequently, it seems necessary to erect a new name. After listing the various names, revising the subgenus and genera attributed to Triloculina laevigata, and comparing fossil and recent specimens, the name: Affinetrina alcidi Levy et al., 1992a, is confirmed.
本研究的目的是澄清三叶虫(Triloculina laevigata Orbigny, 1826, no . nud)引起的问题。福纳西尼于1905年描述并描绘了这一现象。另一个物种，也被称为三叶虫，是由Bornemann在1855年创造的，奥比尼的特定名称变得无效。这种无效只是最近才被评估，许多作者仍然使用原来的分配。因此，似乎有必要树立一个新的名称。经过对各种名称的整理，修正了属于laevigata的亚属和属，并比较了化石和最近的标本，确定了名称:Affinetrina alcidi Levy et al.， 1992a。

During the period from 1976 to 2014, the distribution of brachiopods along the French Mediterranean coasts was particularly well investigated, especially in the Bathyal zone. From 1983 to 1989, the study of this zoological group was the aim of the RCP-CNRS No 728 whose data of the expeditions are the purpose of this ebook: the results concern five species occurring in the Upper Bathyal, i.e., Novocrania anomala, Gryphus vitreus, Terebratulina retusa, Megathiris detruncata, Platidia anomioides and Mergerlia truncata. They are developped over nine chapters, the latter two on the notebooks of samples in the surveyed stations and their distributional charts, as well as those of the five brachiopod species. The occurrences in Mediterranean biocoenoses have revealed biases with the systematics when restricted to shell characters because phylogenetic methods are needed in living species. Another highlight raises questions about the validity of some related fossil species, Terebratula minor (= Gryphus vitreus) is taken as example herein. Finally, the infestation of G. vitreus shells by the Ostreobium alga led to discuss again about the lower limit of the benthic phytal system and its bathymetric variations as far as in the Bathyal.

Teichichnus burrows occur in the Sandbian, Katian and Telychian of Estonia associated with carbonate rocks. It is possible that Teichichnus is more common in the Sandbian than in the Lower to Middle Ordovician and in the Silurian. Two ichnospecies, T. rectus and T. patens, have been identified from the Lower Paleozoic of Estonia. This is the first record of T. patens in the Ordovician of Baltica. Teichichnus in the Sandbian, Katian and Telychian of Estonia is restricted to the shallowest tier levels. The rarity of Teichichnus in the carbonate sequences of the Ordovician and Silurian of Estonia reflects little bathymetric variability and an extremely low sedimentation rate in the shallow epicontinental basin.

The present paper examines the type specimens of the bivalve and gastropod taxa described by Gaetano Rovereto in the years 1897-1914 coming from the Oligocene rocks of Santa Giustina and Sassello areas (Molare Formation, Tertiary Piedmont Basin, Central Liguria, NW Italy). These taxa are part of the "Collezione BTP" (BTP Collection) housed at the Dipartimento di Scienze della Terra, dell'Ambiente e della Vita DISTAV of the Universita di Genova. The collecting sites reported in the Rovereto's papers and indicated on labels have been reinvestigated in the field. 22 taxa (6 gastropods and 16 bivalves) are revised and re-documented; 6 have been recognized as younger synonyms of other species, the others are valid taxa. The majority of this fauna is restricted to the Oligocene time and to the Tertiary Piedmont Basin.
本文研究了Gaetano Rovereto在1897-1914年间描述的双壳类和腹足类的模式标本，这些标本来自意大利西北部利古里亚中部第三纪皮埃蒙特盆地Molare组的Santa Giustina和Sassello地区的近新世岩石。这些分类群是“Collezione BTP”(BTP收藏)的一部分，该收藏位于热那亚大学的Dipartimento di Scienze della Terra, dell'Ambiente e della Vita DISTAV。在Rovereto的论文中报告的和标签上指出的收集地点已在实地重新调查。对22个分类群(6个腹足类和16个双壳类)进行了修订和重新记录;6个已被确认为其他种的年轻近义词，其余为有效分类群。这些动物群大多局限于渐新世和第三纪山前盆地。
