Opis:
Provanna marshallisp. nov. is described from Early to Middle Miocene−age fossil hydrocarbon seep localities in the East Coast Basin, North Island, New Zealand, adding to 18 modern and three fossil species of the genus described. Modern species are well represented at hydrothermal vent sites as well as at hydrocarbon seeps and on other organic substrates in the deep sea, including sunken wood and whale falls. Described fossil Provanna species have been almost exclusively reported from hydrocarbon seep deposits, with a few reports of suspected fossil specimens of the genus from other chemosynthetic environments such as sunken wood and large vertebrate (whale and plesiosaurid) carcasses, and the oldest occurrences are dated to the Middle Cenomanian (early Late Cretaceous). The New Zealand fossil species is the most variable species of the genus described to date, and its shell microstructure is reported and found to be comparable to the fossil species Provanna antiqua and some modern species of the genus.

Opis:
Clusters of gastropod egg capsules, inferred to be of neritoids and attached to the inner shell wall of the ultimate whorl of a large volutid gastropod, are here recorded from the upper Nekum Member (Maastricht Formation; late Maastrichtian) of the ENCI−Heidelberg Cement Group quarry, St Pietersberg (Maastricht, southeast Netherlands). Because the aragonitic shell of the volutid has dissolved, the outlines of the egg capsules are now revealed on the steinkern of indurated biocalcarenite, having been subsequently overgrown by cheilostome bryozoan colonies and preserved as mould bioimmurations. This represents the first example of gastropod eggs preserved through bioimmuration, as well as the first record of gastropod eggs from the Cretaceous.

Opis:
Small round holes in the tests of fossil echinoids present problems of interpretation, the most obvious questions being who did it and why? Both have been the cause of considerable conjecture by ichnologists and echinoderm palaeontologists. “Drill holes” described from the Miocene of Poland in the echinoid Echinocyamus linearis Capeder are classified within the ichnospecies Oichnus simplex Bromley. Contrary to the original analysis, the possibility remains that some of these holes were the result of eulimid parasitism rather than predation by juvenile cassids. If other, larger echinoids in the fauna suffered predation by adult cassids, then the available samples are probably too small for it to be recognised.

Opis:
The diversity of residual colour patterns is revealed for the first time in the European fossil Ampullinidae. The colour patterns were studied under Ultraviolet (UV) light in approximately 3100 specimens belonging to 83 species, 12 genera (Ampullina, Globularia, Crommium, Amaurellina, Pachycrommium, Amauropsina, Ampullonatica, Eocernina, Ampullinopsis, Vanikoropsis, Pictavia, and Ampullospira) and three subgenera (Globularia, Deshayesia, and Cernina within the genus Globularia). Forty−six Cainozoic species revealed residual colour patterns and 29 of them, belonging to six genera (Ampullina, Globularia, Crommium, Amaurellina, Pachycrommium, Amauropsina), are described herein as examples representing the entire diversity of the encountered colour patterns. These patterns are most diverse during the Middle Eocene coincident with the period of highest taxonomic diversity of the Ampullinidae. Four basic classes, regarded as containing possible homologous colour patterns in terms of pigments incorporation modalities, are proposed. Class I, a fluorescent wide diffuse area or spiral stripes, occurs in most of the species, while the three others are more peculiar. Class II, fluorescent axial zigzagging stripes, Class III, fluorescent axial to slightly opisthocline stripes or segments, and Class IV, fluorescent patches forming axial segments by coalescence, allow an easy distinction between the genera Globularia, Pachycrommium, and three peculiar species of Ampullina. The bauplan of the colour patterns revealed in Globularia is very similar to that of the single extant species, Globularia (Cernina) fluctuata. This supports the view of previous authors who classified them in the same genus. Furthermore, at the family level, the peculiar residual patterns belonging to classes II, III, and IV have not been observed in naticid gastropods. Thus our results for the Cainozoic fossil record are consistent with the conclusions based on anatomy and feeding habits, namely that ampullinid gastropods, regarded for a long time as belonging to the family Naticidae, constitute a family apart.

Opis:
Late Frasnian–Early Famennian entomozoacean ostracod assemblages from the Płucki section in the Holy Cross Mountains were studied to establish the effect of the “Kellwasser bio−event” on the planktonic biodiversity and faunal content. The composition of ostracod assemblages changes from a moderately diverse (10 species) Entomoprimitia–Richterina– Nehdentomis–Nandania dominated “background” assemblage characterising a pre−event interval, to an Entomoprimitia−assemblage during the event interval, and finally to a Franklinella−dominated post−event assemblage in the Middle Palmatolepis triangularis conodont Zone. The Frasnian–Famennian extinction caused substantial losses among entomozoacean lineages. In the Płucki section it occurred in two closely spaced steps within the Palmatolepis linguiformis conodont Zone. The first step, at the base of the dark cephalopod limestone (Upper Kellwasser Horizon), reduced the abundance and the species diversity of entomozoaceans to only two Entomoprimitia species. The vacant niche was then filled by the new, immigrant species Entomoprimitia (Entomoprimitia) kayseri which is dominant in the Upper Kellwasser interval. All these species were lost at the second step within the Upper Kellwasser Horizon. The entomozoaceans remained virtually absent during a long time interval between the end−Frasnian crisis and the Middle Pa. triangularis Zone. They reappear as new species from refugia lineages (Franklinella, Nehdentomis) and became widespread, indicating favourable ecological conditions. Some 13 species have been identified and assigned to seven genera. Rabienella? lagowiensis sp. nov. is proposed.

Opis:
Sixteen gastropod species from two Campanian (Upper Cretaceous) hydrocarbon seep localities in Hokkaido, Japan are described. Seven species are new: the acmaeid limpet Serradonta omagariensis; three turbinids: Homalopoma abeshinaiensis, Cantrainea yasukawensis, and C. omagariensis; the trochid Margarites sasakii; the seguenzioid Cataegis nakagawensis; and the provannid Provanna nakagawensis. The most common species in the investigated localities are acmaeid limpets (S. omagariensis), tiny turbinids (H. abeshinaiensis, C. yasukawensis, C. omagariensis), and provannids/hokkaidoconchids (P. nakagawensis and Hokkaidoconcha hikidai). The Upper Cretaceous associations described here do not resemble Lower Cretaceous associations known from other regions but are composed of species similar to gastropods from Recent hydrocarbon seeps and hydrothermal vents in the Northwestern Pacific. This strongly suggest that this region possesses a regional pool of gastropods in chemosynthesis−based communities at least since Late Cretaceous time. The only group of gastropods described here which has no Recent counterpart is the Hokkaidoconchidae. A comparison to gastropods from plesiosaur falls and sunken wood of the same age and region strongly suggest that these invertebrate communities do not differ significantly from the coeval hydrocarbon seep communities described herein.

Opis:
Drill holes on tests of Echinocyamus linearis from the Middle Miocene Korytnica Basin represent the first well documented fossil record of cassid predation from Poland. These traces complement the ecological information on the size and structure of cassid populations recorded by body fossils. The high number of drill holes recognised from the Heterostegina Sands, the uppermost part of the Korytnica depositional sequence, indicates the occurrence of a large cassid population during the late stage of development of the Korytnica Basin. The small size of most of the drill holes indicates that juvenile gastropods of the family Cassidae, which are not preserved in the fossil record of the investigated area, were also present in the cassid populations.

Opis:
We studied the shell and penis morphology, and cytochrome oxidase subunit I (COI) gene sequences, in minute, valvatiform hydrobiid gastropods from Slovensky Kras, Slovakia. The morphology confirmed the assignment of the studied snails to the genus Hauffenia, while in the molecular tree they were placed within the Hydrobiidae, and not close to Hauffenia. The results indicate that the Slovak valvatiform hydrobiids are two taxa which presumably represent two genera: Hauffenia Pollonera, 1898 and Lobaumia Haase, 1993. More molecular data on the Austrian and Hungarian taxa are needed.
