Abstract:

New material comprising more than four thousand specimens of planktonic foraminifers from the lowermost Danian Cerithium Limestone at Stevns Klint, Denmark, reveal significant lateral biostratigraphic differences along the 14 km long cliff. The Cerithium Limestone at Rødvig (Korsnæb) in the southern part of Stevns Klint is dominated by foraminiferal assemblages indicative of the Parvularugoglobigerina eugubina Zone (Pα). This pattern changes laterally towards the north, where the P. eugubina Zone becomes gradually thinner. At the northernmost locality investigated, Holtug quarry, the Cerithium

Abstract:

Two ammonite species, Baculites vertebralis and Hoploscaphites constrictus, are recorded from the Cerithium Limestone (lower Danian, Paleogene) at Stevns Klint, Denmark. Most of the specimens represent internal and external moulds of shell fragments, the sole exception being a complete, well preserved internal mould of H. constrictus. The infilling of the body chamber and phragmocone of this specimen is indistinguishable from the surrounding limestone. The ð13C value for the phragmocone fill is 1.382, matching Danian values much better than the more positive Maastrichtian values for the fine-f

Abstract:

Morphotype ratios among planktonic foraminifers are used as a stratigraphic tool within the Cerithium Limestone, part of the lowermost Danian type sequence at Stevns Klint, Denmark. Enhanced stratigraphic resolution provided by the method indicates that the base of the limestone is diachronous, becoming progressively younger northwards. The bivalve fauna of the Cerithium Limestone represents an early recovery fauna exhibiting a gradual recovery pattern from zero species at the stratigraphic base of the limestone to a rather constant level about 20 species through the upper half of the unit.

In Clibanarius virescens, males rotate the female's shell about an axis perpendicular to the female's shell aperture axis while holding the shell with their ambulatory legs. in Diogenes avarus, males hold the female's shell with their minor cheliped in an unusual orientation in which the female's shell aperture is facing away from the male. In D. avarus, both field and laboratory observations indicate that males in longer-spired shells such as Cerithium spp. are apparently at a disadvan

It has been observed previously that the digestive gland of the carnivorous gastropod mollusc, Murex trunculus, does not accumulate metals which occur in high concentration in the digestive gland of its prey, the detritus-feeding gastropod, Cerithium vulgatum. It is proposed that mechanisms of metal detoxification which operate in C. vulgatum render metals biologically unavailable to M. trunculus. In the present work, this scheme is tested by feeding tissues containing detoxified metals from a gastropod, bivalve and barnacle to carnivorous gastropods.

Abstract:

During night dives along randomly selected transects across sand, seagrass, and rubble on the reef flat of Looe Key, a spur-and-groove coral reef, spiny lobsters (Panulirus argus) from dens on the forereef were observed foraging on the reef flat, particularly on the extensive rubble ridge and also relatively frequently in Thalassia. Subsequent sampling of the rubble revealed hundreds of taxa of appropriate prey items, many at high densities; the density of Cerithium litteratum, a favoured food item, was as high as 180 individuals m-2. Arthropods, especially spider crabs (Pitho spp.), were comm

Abstract:

Ten new species of fossil gastropods from the upper Miocene (Tortonian) of the Canary Islands (Spain) are described. Among these are three species of the genus Patella, a group with few fossil representatives, as well as three others representing the family Trochidae. The remaining new species represent Caenogastropoda. This study improves our knowledge of the fossil malacofauna from the Miocene of these islands. Together with the Azores and Madeira archipelagos, the Canaries belong to the Macaronesian biogeographic region. The described species are indicative of rocky coastal environments, an

The population of the hermit crab Pagurus criniticornis (Dana, 1852) was studied based on seasonal abundance, size frequency distribution, sex ratio, reproductive period, fecundity and shell relationship. Specimens were collected monthly by SCUBA diving in the infralittoral area of Anchieta Island, Ubatuba. A total of 1,017 individuals was analyzed. Animal size (minimum and maximum shield length, respectively) was 0.7 and 2.9 mm for males, 0.6 and 2.8 mm for non-ovigerous females, and 1.0 and 2.5 mm for ovigerous females. The sex ratio was 1:1.29. Sexual dimorphism was recorded by the presence

Abstract:

A greater amount of organic matter and the higher productivity in sheltered environments, such as muddy beaches, can be attributed to the presence of bacteria and plants, which provide more food in these environments than in exposed sandy beaches. However, the influence of this productivity on the population biology of different trophic levels has not been adequately assessed in sheltered environments. We examined the variation of population dynamics and secondary production of two intertidal gastropods, the herbivorous Cerithium atratum and the scavenger Nassarius vibex, in a sandflat environ

This is the first study of bony fish remains across the K/Pg boundary section at Stevns Klint, Denmark. The studied specimens comprise one partly preserved articulated skeleton, a few isolated bones, and casts from several otolith imprints and voids. As otoliths are aragonitic, the remains are all dissolved. The imprints of the otoliths originate from the uppermost Maastrichtian Højerup Member or ‘Grey Chalk’, and the bone fragments and the partial skeleton were obtained from the Fiskeler Member directly above the K/Pg boundary. Further otolith imprints originated from the basal Danian Cerithi
