Sont décrits les microfossiles des sédiments marins du Jurassique supérieur, extraits du sondage à Magnuszew et appartenant aux groupes suivants: les Dinoflagellés, les Acritarches, les microfossiles incertae sedis et les Algues sédentaires. Les Dinoflagellés appartiennent à 12 espèces, parmi lesquelles ont été distingués 2 nouveaux genres: Tetrasphaera n.gen, et Palaeosphaerium n.gen., ainsi que 5 nouvelles espèces: Palaeoperidinium nuciformoides n.sp., P. rhomboidalis n.sp., Hystrichosphaeridium polonicum n.sp., Tetrasphaera rara n.sp. et Palaeosphaerium infrequens n.sp. Parmi les Acritarches on a distingué 4 espèces, et parmi les microfossiles incertae sedis - 3 espèces attribuées aux deux genres nouveaux; ce sont: Dictyochroa ovalis n.gen., n.sp., Alisum magnum n.gen., n.sp. et Alisum parvum n.sp. Sont décrits, en outre: un microfossile problématique, génériquement et spécifiquement indéterminable, ainsi que deux menues Algues, appartenant, probablement, aux Chlorophycées. Une liste de la répartition stratigraphique des microfossiles, se trouvant dans les échantillons examinés, est jointe au travail.

Ichthyosaurs rapidly diversified and colonised a wide range of ecological niches during the Early and Middle Triassic period, but experienced a major decline in diversity near the end of the Triassic. Timing and causes of this demise and the subsequent rapid radiation of the diverse, but less disparate, parvipelvian ichthyosaurs are still unknown, notably because of inadequate sampling in strata of latest Triassic age. Here, we describe an exceptionally large radius from Lower Jurassic deposits at Penarth near Cardiff, south Wales (UK) the morphology of which places it within the giant Triassic shastasaurids. A tentative total body size estimate, based on a regression analysis of various complete ichthyosaur skeletons, yields a value of 12-15 m. The specimen is substantially younger than any previously reported last known occurrences of shastasaurids and implies a Lazarus range in the lowermost Jurassic for this ichthyosaur morphotype.

Elusive tracks of stegosaurs have been long searched for by ichnologists, and various purported stegosaur imprints have recently been reported. A fragmentary trackway of a large, quadrupedal ornithischian dinosaur was found on an isolated slab of Oxfordian dolomite, on the northeastern slope of Holy Cross Mountains, Poland. The track is similar to large, blunt−toed Late Jurassic ichnites from North America. The footprints show a distinctive morphology, which fits the stegosaurian foot. The newly described ichnites from the Upper Jurassic of Poland provide the second ichnological evidence of the Late Jurassic dinosaurs in this country; numerous rich dinosaur footprint assemblages were previously known only from the Lower Jurassic outcrops.

Early Jurassic aragonitic foraminifers are outstandingly well-preserved in the Marmorea crust, a multiphased ferromanganese layer limiting the Schnöll and Adnet formations (Adnet, Northern Calcareous Alps, Austria). This remarkable preservation, related to the pervasive impregnation of aragonitic tests prior to their recrystallization, allowed observing unknown diagnostic features of the genus Involutina, which typifies the Suborder Involutinina. Thanks to a detailed examination of the Adnet specimens, this paper clarifies the taxonomy, systematic position, and phylogeny of Involutina. A new diagnosis, structural model, and lineage are introduced for the group. Involutina is the direct descendant of Aulotortus and the two taxa probably showed a parallel evolution. As Aulotortus, Involutina presents a high intraspecific variability and its diversity must be revised downward. Current phylogenetic and taxonomic frames of the Suborder Involutinina are firmly questioned as, contrary to previous schemes, the type-genus possesses more than one lamellar deposit per whorl. In Involutina, the height and distribution of papillae on the test surface is not random and probably related to a biological function. We here propose that the papillose lamellae and tube infoldings that characterize representatives of the genus were rudimentary features for light catching and symbiont positioning, respectively.

Jurassic rhynchonellide brachiopods from the Jordan Valley are herein revised and new taxa are added to the faunal list. In this study of Jurassic rhynchonellides from Wadi Zarqa, northwestern Jordan, we recognize the following taxa: Eurysites rotundus, Cymatorhynchia quadriplicata, Daghanirhynchia triangulata, D. angulocostata, Pycnoria magna, Schizoria elongata, and Schizoria cf. intermedia. The following new taxa are described: Daghanirhynchia susanae sp. nov. and Amydroptychus markowitzi sp. nov. The Middle Jurassic Mughanniyya Formation of northwest Jordan is dominated by limestone beds. The sedimentary environment is interpreted as neritic, light, and nutrient−rich resulting in high faunal diversity. The high rhynchonellide endemism of this fauna is yet another confirmation of pronounced Middle Jurassic endemism along the southern Tethyan margin of the Ethiopian Province. Brachiopods of the Jordanian Mughanniyya Formation can be correlated with the fauna of the Aroussiah Formation in Sinai and the Zohar and Matmor formations in Southern Israel.

Sont décrits des Madréporaires provenant de l'Oxfordien supérieur et du Kimméridgien inférieur de la bordure des Monts de Sainte-Croix (Góry Świętokrzyskie). Ils représentent 69 espèces (12 nouvelles), réparties en 33 genres, dont 3 nouveaux; 66 espèces sont des formes coloniales, et 3 - des formes simples. Plus de 60% d'espèces coloniales ont la structure rameuse, ou plus ou moins lamellaire. Chez quelques unes des études sur le bourgeonnement ont été effectuées. Les formations madréporiques du Jurassique supérieur des Monts de Sainte-Croix sont constituées essentiellement de Coraux (généralement en position de vie), associés aux Algues (Solénopores) et accompagnés d'une faune, plus ou moins abondante, de Mollusques, Échinodermes et Brachiopodes, englobés dans des sédiments pélitiques ou organodétritiques. Dans ce milieu les colonies de Coraux ne formaient que de basses touffes et d'étendus bancs.

Mount Flora at Hope Bay, in northernmost part of Antarctic Peninsula, is a famous Jurassic flora locality. It has already been studied for a hundred years, but however, it is still possible to find there new taxa. Based on two species of liverworts found at Mount Flora (Schizolepidella gracilis and Schizolepidella birkenmajeri sp. nov.), the present study discusses affiliation of the genus Schizolepidella to liverworts. The new species Schizolepidella birkenmajeri is erected.

Twenty two species of Jurassic Rudistae (induding 11 new ones) have been described from the margin of the Holy Cross Mountains (Góry Świętokrzyskie). A new genus Macrodiceras has also been erected. Conditions of asymmetry among the Rudistae have been discussed and their presumable causes analyzed. The influence exerted by ecological-facial factors on the development of the Rudistae has also been presented. Problems of the phylogeny of the Rudistae and their stratigraphic importance are discussed. The growth changes of shells in some species are described.

Eleven trigoniid species of the genera Trigonia Bruguiere, Myophorella Bayle and Rutitrigonia van Hoepen, including one new species, R. skorkovensis. sp.n., are described from the Jurassic of Poland. The representatives of the genus Rutitrigonia are reported for the first time from the Lower Kimmeridgian of Poland which markedly increases the stratigraphic and geographic range of that genus hitherto considered as limited to the Upper Kimmeridgian - Upper Cretaceous of the Phillippines, Japan and the southern hemisphere.

Eleven new tracks from the Upper Jurassic of Portugal are described and attributed to the stegosaurian ichnogenus Deltapodus. One track exhibits exceptionally well−preserved impressions of skin on the plantar surface, showing the stegosaur foot to be covered by closely spaced skin tubercles of ca. 6 mm in size. The Deltapodus specimens from the Aalenian of England represent the oldest occurrence of stegosaurs and imply an earlier cladogenesis than is recognized in the body fossil record.

Postcranial skeletal pneumaticity (PSP) is present in a range of basal sauropodomorphs spanning the basal sauropodomorph–sauropod transition. We describe the PSP of five taxa, Plateosaurus engelhardti, Eucnemesaurus fortis, Aardonyx celestae, Antetonitrus ingenipes, and an unnamed basal sauropod from Spion Kop, South Africa (hereafter referred to as the Spion Kop sauropod). The PSP of Plateosaurus is apparently sporadic in its occurrence and has only been observed in very few specimens, in which it is of very limited extent, affecting only the posterior cervical vertebrae and possibly the mid dorsals in one specimen. The PSP of Eucnemesaurus, Aardonyx, Antetonitrus, and the Spion Kop sauropod consists of subfossae (fossa−within−fossa structures) that excavate the vertices of the posterior infradiapophyseal fossae of the posterior dorsal vertebrae. These subfossae range from simple shallow depressions (Eucnemesaurus) to deep, steepsided, internally subdivided and asymmetrically developed chambers (Antetonitrus). The middle and anterior dorsal vertebrae of these taxa lack PSP, demonstrating that abdominal air sacs were the source of the invasive diverticula. The presence of pneumatic features within the infradiapophyseal fossae suggest that the homologous fossae of more basal saurischians and dinosauriforms were receptacles that housed pneumatic diverticula. We suggest that it is probable that rigid non−compliant lungs ventilated by compliant posterior air sacs evolved prior to the origination of Dinosauria.

The genus Laevitomaria is reviewed and its palaeobiogeographical history is reconstructed based on the re-examination of its type species L. problematica, the study of material stored at the National Natural History Museum of Luxembourg, and an extensive review of the literature. The systematic study allows ascribing to Laevitomaria a number of Jurassic species from the western European region formerly included in other pleurotomariid genera. The following new combinations are proposed: Laevitomaria allionta, L. amyntas, L. angulba, L. asurai, L. daityai, L. fasciata, L. gyroplata, L. isarensis, L. joannis, L. repeliniana, L. stoddarti, L. subplatyspira, and L. zonata. The genus, which was once considered as endemic of the central part of the western Tethys, shows an evolutionary and palaeogeographical history considerably more complex than previously assumed. It first appeared in the Late Sinemurian in the northern belt of the central western Tethys involved in the Neotethyan rifting, where it experienced a first radiation followed by an abrupt decline of diversity in the Toarcian. Species diversity increased again during Toarcian–Aalenian times in the southernmost part of western European shelf and a major radiation occurred during the Middle Aalenian to Early Bajocian in the northern Paris Basin and southern England. After a latest Bajocian collapse of diversity, Laevitomaria disappeared from both the central part of western Tethys and the European shelf. In the Bathonian, the genus appeared in the south-eastern margin of the Tethys where it lasted until the Oxfordian.

A new, relatively diverse gastropod fauna is reported from the Chubut province of west−central Patagonia. The gastropod association at the “El Córdoba” fossiliferous locality (Lower Toarcian of Osta Arena Formation) consists of three new species: the eucyclid Amberleya? espinosa sp. nov. and two procerithiids Cryptaulax damboreneae sp. nov. and Cryptaulax nulloi sp. nov. Other members of the association are the ataphrid Striatoconulus sp., discohelicid Colpomphalus? sp., and an undetermined zygopleurid. Knowledge on Early Jurassic gastropods from South America and other southern continents is reviewed to show that the taxonomic composition of the El Cordoba association strongly resembles other gastropod associations of this age (even those from Europe), suggesting a wide distribution of cosmopolitan genera.
