Opis:
The Prosopidae is an extinct family, consisting mostly of Mesozoic species. Most probably it accommodates the ancestors of all brachyurans in the large sense. The family appeared in the Late Pliensbachian and disappeared at the Early Palaeocene. Evolution of the Prosopidae, and therefore, brachyuran evolution started on Middle Jurassic, shallow, soft bottom marine environments. The world-wide Callovian transgression made possible the formation of bioherms and reefs in the Late Jurassic, creating ecological niches for the rapidly differentiating prosopids. These crabs migrated rapidly all over Europe in the Oxfordian and began to flourish and massively occupied sponge megafacies from Portugal to Poland. In the Kimmeridgian, the area of known prosopids shrank, which has probably been connected with decreasing of the reef facies. In turn, a Tithonian regression in the per-Tethyan area resulted in changes of habitats and in colonisation of the coral reefs. When reef facies retreated at the Jurassic-Cretaceous boundary, the favourable conditions for crab development also vanished, so the known Cretaceous prosopids are rare and spatially dispersed. In Tertiary, the closely related descendants of them, homolodromiids, inhabited preferably soft muddy bottoms in deeper, colder waters.
Kraby z rodziny Prosopidae, reprezentowane są prawie wyłącznie przez gatunki mezozoiczne. Z filogenetycznego punktu widzenia, są one prawdopodobnie przodkami wszystkich pozostałych gatunków krabów. Przedstawiciele tej rodziny znani są od późnego pliensbachu do wczesnego paleocenu. Ewolucja prosopidów, a poprzez to ewolucja pozostałych krabów, rozpoczęła sią w środkowojurajskich, płytkich środowiskach morskich o miękkim charakterze dna. Ogólnoświatowa transgresja kelowejska stworzyła dogodne warunki do powstania różnorodnych bioherm i raf w późnej jurze, które stanowiły nisze ekologiczne dla szybko różnicujących się dzięki temu krabów z rodziny Prosopidae. Kraby te migrowały gwałtownie na całą Europę w oksfordzie, masowo zasiedlając megafację gąbkową i są obecnie znajdowane w utworach tej facji od Portugalii do Polski. W kimerydzie obszar występowania prosopidów wyraźnie się skurczył, co było prawdopodobnie związane ze stopniowym zanikiem tej facji. Z kolei w tytonie regresja w obszarach perytetydzkich spowodowała zmianę środowiska życia krabów i kolonizację przez nie raf koralowych. Dogodne warunki dla rozwoju tych krabów gwałtownie się pogorszyły blisko granicy jury i kredy (zanikanie facji rafowych) skutkiem czego kredowe prosopidy są rzadkie i geograficznie rozproszone. W trzeciorzędzie najbliżsi potomkowie rodziny Prosopidae - kopalni przedstawiciele rodziny Homolodromiidae - zasiedlili środowiska miękkich den głębszych i zimniejszych mórz.

Opis:
No Vendian or lowermost Lower Cambrian deposits have yet been encountered in the Holy Cross Mts. and Nida Trough. The Cambrian of the Holy Cross Mts. is represented by Lower, Middle and Upper Cambrian deposits, containing both macro- and microfossils. The Lower Cambrian begins with deposits containing a non-trilobite fauna that does not allow precise age determination. The overlying Cambrian deposits are subdivided on the basis of trilobite faunas. Unfortunately, the species are often endemic, and correlation with the Scandinavian biostratigraphic scheme is limited.

Opis:
A cladistic analysis of Megadontosuchus arduini from the middle Eocene of Monte Duello (NE Italy) confirms its tomistomine relationships, but the low number of scorable characters determines a low resolution within the tomistomine clade. However, Megadontosuchus is clearly distinct from the other Eocene European or North African tomistomines, in having a moderate elongated but robust rostrum, massive maxillary and dentary teeth and large supratemporal fenestrae. The rostrum and teeth characteristics could indicate that M. arduini had a degree of feeding specialization intermediate between Maroccosuchus zennaroi and the Eocene European tomistomines. A summary of tomistomine palaeobiogeography suggests that despite only one species with a rather restricted range survives at present, such a clade had a glorious past with a world wide distribution documented by a conspicuous fossil record that starts at least in the early Eocene. At present, a detailed knowledge of tomistomine palaeobiogeography is hindered by the lack of modern taxonomic revisions of some fossil remains and therefore by the poor understanding of phylogenetic relationships.

Opis:
The dinosaur footprints cf. Parabrontopodus isp. Lockley, Farlow et Meyer, 1994, attributed to sauropods, have been found in Hettangian (earliest Jurassic) alluvial deposits in Anina (Colonia Ceha Quarry, Resita Basin), belonging to the Getic Nappe in the Southern Carpathians, Western Romania. Heteropodous pes-manus sets and one short, narrow-gauge trackway have been recognized on a large sandstone surface trampled by sauropods. Agreater load was carried by the inner digits of the pes, particularly digit I, and the heel pad is deeply imprinted, which points to a sub-plantigrade pes and gravipodal posture, typical for Eusaropoda. A pentadactyl manus imprint suggestetthat manus digits of early sauropods might have been separate and perhaps more functional when supporting walking on unstable, sticky ground. These tracks, the first find of Jurassic dinosaur footprints in Romania, add an important site to the relatively rare record of earliest Jurassic sauropod footprints. These tracks also confirm that Pangaean islands and peninsulas around the Western Tethys were inhabited by early sauropods. These peninsulas or islands, including a hypothetical "Moesian Island", must have been at least temporarily connected with the mainland. The sizes of the Romanian footprints are similar to the Hettangian Parabrontopodus isp. tracks described from Poland (mainland Pangaea — Eurasian area) and Italy (Tethyan domain) and do not indicate insular dwarfism.

Opis:
The separation of Laurasia and Gondwana, which was initiated by the Triassic break-up of Pangea, continued during Early-Middle Jurassic times. The origin of the narrow sea strait. so-called "Hispanic Corridor", took place between these two continents and connection of the Panthalassa Ocean (Proto-Pacific) and western (Alpine) Tethys gradually started in Early Jurassic, most probably in Sinemurian-Pliensbachian times. Recovery of marine fauna after Triassic/Jurassic mass extinction event was mainly marked by world-wide distribution of Lithiotis-type bivalve buildups. They indicate mainly shallow-marine/lagoon-type carbonate sedimentation and palaeogeographic/geodynamic regimes during break-up of Pangea in Pliensbachian-Early Toarcian times.

Opis:
The Oxfordian ammonite group Passendorferiinae (known as "Mediterranean perisphinctids") forms a group of perisphinctids characterized by strongly evolute serpenticone coiling and subcircular to subquadrate whorl section, and forms a lateral divergent branch of the main stem Perisphinctidae. They originated probably from Late Callovian Grossouvriinae (Alligaticeras) and spread mainly in the Mediterranean (Tethyan) Province along the southern margin of Tethys, occasionally reaching the outer areas of epicontinental platforms. Their particular morphological features make them somewhat homoeomorphic with Tethyan Kimmeridgian Nebrodites. The phyletic link might be represented by the genus Geyssantia Meléndez, known from the Late Oxfordian Planula Chronozone. Separate biogeographic distribution in relation to the Perisphinctinae might reflect a progressive differentiation of western Tethyan faunas at the Callovian-Oxfordian boundary and at the onset of the Middle Oxfordian Transversarium Chronozone. Their rapid evolution gives them a biostratigraphic value similar to that of the Perisphinctinae. At the turn of the Middle-Late Oxfordian they gave rise to early Ataxioceratinae (Orthosphinctes), which replaced the Perisphinctinae in epicontinental areas, and colonised the marginal epicontinental blocks of northern Tethys. The taxonomy of this group is based upon the recognition of sexual dimorphism, using a single generic and specific name for both (M) and (m), and hence rejecting the use of former subgeneric ames for both dimorphs. A new species within this line: Passendorferia nodicostata sp. nov. from the Plicatilis Biozone (Paturattensis Subbiozone) is defined and described for the first time.

Opis:
Skeletal remains, some loose on the surface and others still embedded, have been recovered from the uppermost part of an outcrop of the Permian Cala del Vino Formation located near Torre del Porticciolo (Alghero, Nurra, NW Sardinia). Taphonomic analysis suggests that all the elements pertain to a single individual; ongoing studies indicate the fossil represents a large caseid close (or referable) to Cotylorhynchus; otherwise restricted to a narrow geographic and stratigraphic zone of the central USA. The new finding, the first of a caseid in Italy and one of few in Europe, enlarges the known distribution of the family and provides a significant and key chronostratigraphic constraint for the continental succession of this area and, in turn, helps establish a stratigraphic framework for the Permian units cropping out in Italy and southern France.

Opis:
The precise record of simoceratins sampled bed−by−bed is first reported from Mexico (Mazatepec area in Puebla, central−eastern Mexico), as well as the existence of lappeted peristomes in these ammonites. Both Pseudovolanoceras aesinense and the subspecies Pseudovolanoceras aesinense chignahuapense are shown to occur among Mexican simoceratins. The European species and the Mexican subspecies share the same stratigraphic range in the studied sections, yet they differ in ephebic sculpture. Ecological adaptation to neritic seas corresponding to eastern Mexico areas is interpreted, forcing phenotypic deviation with geographic significance, i.e., subspeciation. The new subspecies would indicate stratigraphic horizons within the Semiformiceras semiforme/Haploceras verruciferum Chronozone in the Mediterranean Tethys. A revision of contemporaneous simoceratins in the Americas is founded on a comparative analysis with respect to the European species P. aesinense.

Opis:
This is the first Paratethyan record of a minute scallop species Parvamussium fenestratum (Forbes, 1844). The species was found in Middle Miocene (Upper Badenian) clayey deposits in the Surzha borehole, the Ukrainian Carpathian Foredeep Basin. Examination of other Parvamussium specimens stored in the Museum of the Earth in Warsaw and in the Hungarian Natural History Museum in Budapest revealed further Paratethyan records of Parvamussium fenestratum. These specimens, previously referred to Parvamussium felsineum (Foresti, 1893), were identified in the Middle Miocene faunas of Poland (Monastyrz and Długi Goraj, Roztocze Hills) and Hungary (Makkoshotyka, Tokaj Mts.). In the Mediterranean Neogene this extremely rare species has been reported from the Lower Miocene (uppermost Burdigalian) of Italy and from the Lower Pliocene (Zanclean) of Spain. Research on the Oligocene-Miocene succession in the Paratethys has shown representatives of Parvamussium Sacco, 1897 to be moderately abundant in clayey facies in different basins and the genus is regarded as biostratigraphically important. Data on the distribution of other Paratethyan and Neogene Mediterranean Parvamussium species viz., Parvamussium bronni (Mayer, 1861), P. duodecimlamellatum (Bronn, 1831), P. felsineum (Foresti, 1893) and P. miopliocenicum (Ruggieri, 1949) are reported. Finally, palaeobiological and palaeobiogeographical characteristics on the genus Parvamussium Sacco, 1897 the Early Cretaceous to Recent time span are described.

Opis:
In Egypt, marine Upper Cenomanian.Turonian strata are well exposed in the Eastern Desert. The southernmost outcrops are located in the central part of Wadi Qena, where the lower Upper Cretaceous is represented by the fossiliferous Galala and Umm Omeiyid formations. From these strata, numerous ammonites have been collected bed-by-bed and 13 taxa have been identified, which are systematically described herein. Four of them (Euomphaloceras costatum, Vascoceras globosum globosum, Thomasites gongilensis and Pseudotissotia nigeriensis) are recorded from Egypt for the first time. The ammonite ranges are used for a biostratigraphic zonation of the lower Upper Cretaceous succession in the northern and central part of Wadi Qena: the Upper Cenomanian.Lower Turonian has been subdivided into five biozones (including a new upper Lower Turonian biozone based on the occurrence of Pseudotissotia nigeriensis), and one biozone has been recognized in the Upper Turonian. Palaeobiogeographically, the ammonite assemblage has a Tethyan character. During the Early Turonian, influences of the Vascoceratid Province were predominant with strong affinities to typical Nigerian faunas. This shows the significance of faunal exchange between Egypt and Central and West Africa via the Trans-Saharan Seaway. Compared to contemporaneous ammonoid faunas from the northern part of the Eastern Desert, Boreal influences are much less obvious in Wadi Qena. Thus, the present study greatly enhances the knowledge of the Late Cretaceous palaeobiogeography and biostratigraphy of Egypt and adjacent areas.

Opis:
Sixty-two Middle Devonian brachiopod species are described on the basis of >1300 specimens from the Taboumakhlof Formation (and subordinately probably also from the top of the El Otfal Formation) at Madne el Mrakib (middle to late Eifelian or early Givetian?), Aferdou el Mrakib (late Eifelian to middle Givetian), and Guelb el Maharch (early Givetian) on the southern edge of the MaÎder Syncline (eastern Anti-Atlas, Mo- rocco). Representatives of Craniida (2 taxa), Strophomenida (5), Productida (2), Orthotetida (2), Orthida (5), Pentamerida (5), Rhynchonellida (9), Atrypida (14), Athyridida (7), Spiriferida (9), and Spiriferinida (2) are present. The fauna is dominated quantitatively by the Atrypida (24% of taxa, about the half of specimens, and the commonest species Atryparia dispersa making up about 13% of the material); the Rhynchonellida (16% of taxa, about one-sixth of specimens) are the second largest order. A new genus of the family Pugnacidae (order Rhynchonellida), Paulinaerhynchia, is proposed with the type species P. paulinae gen. et sp. nov. from Maharch; it is closest to Pugnax, from which it differs in distinct costation, lack of a dorsal septum and septalium, and rudimentary dental plates. Desquamatia (D.) deserti sp. nov., a large and finely costate representative of the genus, is described also from Maharch. Antirhynchonella and Glosshypothyridina are reported for the first time or con- firmed to be present in the Givetian. Forty (possibly up to 46) species (71 or possibly up to 82% of the taxa identified at the species level) are present also in either Eifel (Germany) or the Holy Cross Mountains (Poland). Such a high ratio of species in common attests to unconstrained faunal exchanges among benthic faunas between the northern and southern shores of the Variscan Sea during the Middle Devonian. This favours the palaeogeo- graphic hypothesis of a narrow Variscan Sea.

Opis:
Ammonites Mortoniceras (Subschloenbachia) sp. are preserved as attachment scars on the oyster shells from the topmost portion of the Albian succession at Annopol, Poland. These oyster-bioimmured ammonites show a closest affinity to the representatives of Mortoniceras (Subschloenbachia) characteristic of the upper Upper Albian Mortoniceras perinflatum Zone. No ammonites indicative of the uppermost Albian–lowermost Cenomanian Praeschloenbachia briacensis Zone are recorded. Thus, the hiatus at the Albian–Cenomanian boundary at Annopol embraces the latter zone. The presence (and dominance) of Mortoniceras in the upper Upper Albian ammonite assemblage of Annopol suggests that the representatives of this Tethyan genus could migrate into the epicratonic areas of Poland directly from the Tethyan Realm, via the Lwów (Lviv) region.

A new species of micromorphic articulate brachiopod (Rhynchonellida) Lambdarina jugowiensis sp. nov., from the upper Viséan (Sokolec Beds) of central Sudetes, SW Poland, is described. The studied specimens are calcified, what makes them unique in respect of their state of preservation. The material is represented by a full range of growth stages; from brephic to gerontic. Based on its morphological features and the palaeogeographical distribution of all its known species, two main evolutionary lines are proposed for the genus; the Australian and the European ones. Lambdarina was widely distributed in the equatorial-tropical waters of marginal seas of the Palaeotethys Ocean, mostly during Mississippian time.

Opis:
The investigation of the Late Paleogene to Late Neogene species of rissoid gastropod Galeodinopsis in the Euro-Mediterranean area has supported the hypothesis that this genus is an intermediate form between two well-known rissoids, Alvinia and Manzonia. We recognized four species of Galeodinopsis: G. biangulata, G. germanica sp. nov., G. semperi (new name for Rissoa duboisii), and G. tiberiana. The oldest (very Late Eocene/Oligocene) representatives of Galeodinopsis, G. biangulata, and G. semperi, share similar shell shape and microsculpture with Alvinia. This suggests that Galeodinopsis originated from some Eocene species related to Alvinia. The new species represents the first occurrence within Galeodinopsis of a combination of characters very close to those of Manzonia, above all the typical pitted microsculpture. We hypothesize that Manzonia evolved from Galeodinopsis rather than from the genera Alvania or Alvinia, as previously supposed. Galeodinopsis originated during the very Late Eocene/Oligocene in the North Sea Basin. Afterwards it underwent a strong southward shift to the mid-high east Atlantic and the Mediterranean area, during the Mio-Pliocene, and to the Recent tropical eastern Atlantic coasts, where the type species G. tiberiana still lives. The shift likely was due to a combination of climate cooling and palaeogeographical changes. The distribution of G. biangulata suggests that connections between the North Sea Basin and the Atlantic domain opened through the Channel area at least during the Early Oligocene, earlier than indicated previously. The distribution of Manzonia moulinsi supports the idea of a southern connection to the Atlantic Aquitaine Basin via the Rhine Graben during the Late Oligocene. From a palaeoecological point of view, Galeodinopsis includes warm species with planktotrophic larval development that are typical of the shelf environment in fully marine conditions.

Opis:
The earliest ostracods from the Bohemian Massif (Central European Variscides) have been recorded from the Middle Ordovician of the Prague Basin (Barrandian area), in the upper Klabava Formation, and became an abundant component of fossil assemblages in the overlying Šárka Formation. Both early ostracod associations consist of eight species in total, representing mainly eridostracans, palaeocopids, and binodicopids. The revision, description, or redescription of all species and their distribution in the basin is provided. Their diversification patterns and palaeogeographical relationships to ostracod assemblages from other regions are discussed.
