Abstract A diverse sessile barnacle fauna from a Miocene shallow‐water deposit at Dolnja Stara vas in Slovenia is described. It includes the first descriptions of early post settlement juveniles of Actinobalanus sloveniensis attached to mangrove leaves. These represent three distinct growth phases, the earliest being interpreted as being less than 24 h post settlement, the others being 1 to 2 days post settlement. An assessment of their taphonomy is provided. Associated adult balanomorphs are attached to a variety of organic substrates, including mangrove leaves and branches, fragments of the conifers ? Taxodioxylon , Carapoxylon , pine cones, molluscs, and cetacean bones. The barnacles include A. sloveniensis , Amphibalanus venustus , and Perforatus perforatus —many with opercula retained within the shells. A . venustus retains some of the original shell color. This is the second record of barnacle–plant associations from the Central Paratethys from Kamnik and Trbovlje. The paleoecology and paleogeography of the site are discussed.
The classical locality of Svinary in the eastern Bohemian Cretaceous Basin is the site of new biostratigraphic investigations. Besides some scarce macrofossil evidence, bulk sediment samples were processed to retrieve micropalaeontological assemblages, and calcareous nannofossil smear slides were analysed. The studied material provided calcareous nannofossil assemblages including Micula staurophora, Lithastrinus septenarius and Broinsonia parca expansa , thus documenting the Middle Coniacian (upper part of UC10 Zone and lower part of UC11 Zone). The foraminifera assemblage is relatively rich, planktonic species show a wide stratigraphical range, while the benthic association represented by Neoflabellina suturalis suturalis and Gaudryina carinata is very similar to the Coniacian biozone of Stensioeina granulata-Eponides whitei , valid for the Bohemian Cretaceous Basin. Ostracods are represented by two common cytherellid species, and two rare ornamented species: Imhotepia marssoni ? and Pterygocythereis spinosa . Inoceramid bivalves, namely Platyceramus mantelli , and a newly recorded ammonite, Tridenticeras tridens , support the late Middle Coniacian age of the Svinary outcrop. New biostratigraphic results are given along with palaeoecological interpretations of newly collected fossil material.
Nine specimens of sabellid and serpulid worms which had been figured by Dr. Antonin Fric in his series of publications on the strata of the Bohemian Cretaceous Basin and which are kept in the collection of the National Museum in Prague are re-described, re-figured, re-determined and discussed in detail. The specimens belong to seven species: Glomerula serpentina (GOLDFUSS), Glomerula plexus (J. DE C. SOWERBY), Filograna socialis (GOLDFUSS), Neovermilia cf. ampullacea (J. DE C. SOWERBY), Dorsoserpula wegneri (JAGER), Dorsoserpula conjuncta (GEINITZ)?, and Serpulidae gen. et sp. indet. In addition, those species and specimens mentioned but not figured by Dr. Antonin Fric are listed and partially discussed although these specimens had not been found in the collection and are presumably lost.

Tubes of a new serpulid species, Neovermilia gundstrupensis sp. nov., from the lower part of the Kerteminde Marl Formation (Selandian, middle Paleocene) of Gundstrup gravel pit, Fyn, Denmark, represent the first serpulids of this group from the Selandian of Denmark. Within the long-ranging genus Neovermilia (Oxfordian to Recent), the new finds extend the last recorded occurrence of an informal sub-group of closely related serpulids from the upper Danian to the lower Selandian. Neovermilia gundstrupensis is characterized by a tube increasing only slowly in diameter reaching up to approximately 5 mm and possessing small, often densely spaced annular striae occasionally merging into weakly but never strongly developed annular peristomes. Almost all specimens found so far are attached to siliceous sponges of the genus Ventriculites. The tube morphology of the new species and the microstructure of the tube wall, as well as its palaeoecology are discussed.
