The presence of Ordovician conodont zones from the Late Arenigian (Middle Kunda stage) to the Late Caradocian has been indicated in 8 m thick Mójcza Limestone (Holy Cross Mts, Poland). The conodont fauna of Mójcza is of the Baltic type and decidedly differs from the fauna known from Rzeszówek, situated about 300 km to the west in the Kaczawa Mts (Sudeten Mts). Phragmodus polonicus sp.n. from Mójcza and Erraticodon balticus gen. et sp.n. from a Baltic erratic boulder have been described.
A cosmopolitan spathognathodontid taxon “Ancyrodelloides carlsi” is not regarded in this paper as one of the earliest known representatives of Ancyrodelloides according to former concepts, but is considered as conspicuous member of the genus Lanea. The taxon shows distinct morphological innovation of the upper surface of the Pa element within the Lanea lineage which makes it easily recognizable worldwide and suitable for global correlation. Presented stratigraphic correlation using conodonts and other faunal groups qualifies a short−lived Lanea carlsi as probably the best marker of the middle Lochkovian base. This paper presents reconstruction of the apparatus of L. carlsi which is the first complete reconstruction in the genus Lanea. The comparison of the Lanea apparatus and assumed apparatus of early Ancyrodelloides from the Požáry Quarries (Barrandian, Czech Republic) resulted to proposal of an alternative concept of evolution of these two genera. The relatively short−lived genus Ancyrodelloides is considered to split off from the Lanea clade in the late middle Lochkovian by the entry of Ancncyrodelloides transitans.
Famennian corals of the south-western part of the Holy Cross Mountains (Góry Świętokrzyskie) from Kadzielnia, Zaręby, Łagów (Dule), Gałęzice (Besówka), Kowala and Jabłonna are described in the present work. About 3,000 specimens have been collected and 55 species and 5 subspecies of 36 genera - described. A new family, Kielcephyllidae, two new subfamilies, Friedbergiinae and Guerichiphyllinae, 9 new genera, 36 new species and 5 subspecies have been erected. On the basis of a lithological analysis of beds, faunal assemblages and the preservation state of corallites, it has been concluded that in the Lower Famennian a shallow sea existed at Kadzielnia. It was temporarily connected with the open sea. The corals are mostly preserved there in a life-time place. At Zaręby, there was a lagoon with the remains of plants but with a normal salinity of water. In the Upper Famennian of Gałęzice, the sea water was well aerated and connected with the open sea. Fossils are broken but not worn off and, therefore, they were not transported. At Kowala, the sea was probably calm, not deep and well aerated. Index species for the Lower and Upper Famennian have been determined among the coral fauna examined. The age of individual zones has been determined by conodonts and where such were lacking, climeniids or trilobites. The history of the research of Famennian corals, which in general occur rarely and in monotonous assemblages, has been presented. To settle their generic assignment, the ontogeny of corals has been studied and the results were a basis for changes introduced to the classification. A few phyla have been distinguished and their phylogenetic relationships discussed.
A section containing the Cretaceous/Paleogene (= Cretaceous/Tertiary) boundary in Monmouth County, New Jersey, preserves a record of ammonites extending from the end of the Cretaceous into possibly the beginning of the Danian. The section includes the upper part of the Tinton Formation and lower part of the Hornerstown Formation. The top of the Tinton Formation is represented by a richly fossiliferous unit (the Pinna Layer) that contains many bivalves in life position as well as ammonite jaws preserved inside body chambers. Ammonites include Pachydiscus (Neodesmoceras) mokotibensis, Sphenodiscus lobatus, Eubaculites carinatus, E. latecarinatus, Discoscaphites iris, D. sphaeroidalis, D. minardi, and D. jerseyensis. The Pinna Layer probably represents a relatively short interval of time lasting tens to hundreds of years; it is conformably overlain by the Burrowed Unit, which contains a single fragment of Discoscaphites sp. and several fragments of E. latecarinatus, as well as several isolated specimens of ammonite jaws including two of Eubaculites. Examination of the mode of preservation of the ammonites and jaws suggests that they were fossilized during deposition of the Burrowed Unit and were not reworked from older deposits. Based on the ammonites and dinoflagellates in the Pinna Layer and the Burrowed Unit, these strata traditionally would be assigned to the uppermost Maastrichtian, corresponding to calcareous nannofossil Subzone CC26b. However, a weak iridium anomaly (500–600 pg/g) is present at the base of the Pinna Layer, which presumably represents the record of the bolide impact. Correlation with the iridium layer at the Global Stratotype Section and Point at El Kef, Tunisia, would, therefore, imply that these assemblages are actually Danian, provided that the iridium anomaly is in place and the ammonites and dinoflagellates are not reworked. If the iridium anomaly is in place, or even if it has migrated downward from the top of the Pinna Layer, the ammonites would have survived the impact at this site for a brief interval of time lasting from a few days to hundreds of years.
Three species of bradoriid arthropods from the lower to middle Cambrian transitional interval of Scania, southern Sweden, are described and illustrated: Beyrichona tinea from the top of the traditional lower Cambrian (Gislöv Formation; Ornamentaspis? linnarssoni Zone), and Hipponicharion eos and Alutella sp. from the basal portion of the traditional middle Cambrian (lowermost part of the Alum Shale Formation). The bradoriid fauna compares most closely with others previously described from western and eastern Avalonia (New Brunswick and England). The record of B. tinea suggests a correlation between the “Protolenus Zone” (Hupeolenus Zone) of western Avalonia and the O.? linnarssoni Zone of Scandinavia. Hipponicharion eos appears to be a fairly long−ranging species as it has previously been recorded from upper lower Cambrian or lower middle Cambrian strata in New Brunswick, Poland, and probably Sardinia. The record of H. eos from the lowermost part of the Alum Shale Formation suggests that this largely unfossiliferous interval in the Scanian succession is not younger than the Acadoparadoxides oelandicus Superzone. The genus Alutella has not previously been recorded from the Acado−Baltic Province.
The siliciclastic sequence of the Lower Devonian of the southern part of the Holy Cross Mountains in Poland is renown for abundant vertebrate fossils, including ostracoderm, sarcopterygian, acanthodian, chondrichthyan, and placoderm remains. Study of the vertebrate assemblage from the “placoderm sandstone” from Podłazie Hill in the Holy Cross Mountains reveals that the remains belong to Kujdanowiaspis sp. among other unspecified actinolepids and brachythoracids. The Polish actinolepid material is characterised by sizes bigger than those of the Podolian specimens; this may be related to geographic variation. Owing to the proximity between Podolia and Holy Cross Mountains we suggest that Kujdanowiaspis sp. from the Holy Cross Mountains may be a refugee of some species of Kujdanowiaspis from the Lochkovian–Pragian of Podolia and/or from Spain. Some anterolateral plates provisionally assigned to Arthrodira indet. probably represent a new genus due to the high overlapping surface for median dorsal and anteroventrolateral plates.
Acid-resistant microfossils have been studied from serial bore-core samples representing different facies of Ashgillian deposits. Chitinozoans are shown to hold better promise for detailed subdivision and section correlation than other scarce representatives of macro- or microfauna. According to their vertical distribution, three types of chitinozoan species having biostratigraphic significance can be distinguished.

Silurian and Devonian corals of Japan

72%
Coral assemblages and their faunal sequence for the Silurian and Devonian in four major regions of Japan are reviewed. In Yokokurayama the G₂ fauna with Halysites is Early to Middle Silurian and the G₃ fauna with Schedohatysites is mainly Late Silurian. The Kawauchi Formation of Hikoroichi corresponds to G₃ and a part of G₂. The Okuhinotsuchi Formation of Arisu is mainly correlatable with the G₂. The Ohno fauna of Hikoroichi with Xystriphyllum and the Fukuji fauna are both Early Devonian in age, but their composition is quite different from each other. The Nakazato fauna of Hikoroichi is Middle Devonian. These faunas are composed mostly of cosmopolitan genera. The development of coral faunas may indicate the strong contrast in litho- and biofacies between the Pacific side (outer zone of Southwest Japan and Northeast Japan) and the Japan Sea side (inner zone of Southwest Japan) during the Silurian and Devonian.
Descriptions are given of 103 species and subspecies of the Miliolidae from the Miocene of Poland, including 9 new species and 1 new name. A new genus, Articularia, and a new subfamily, Sigmoilinitinae, comprising species which show a sigmoiline initial stage and not a quinqueloculine or cryptoquinqueloculine one, have also been separated. The distribution and stratigraphic range of the species under study in the Tortonian and Sarmatian of Poland have been discussed and the hypothetical palaeoecologic conditions prevailing in the coastal facies of the Miocene sea reconstructed.
