This paper presents an analysis of the Kislangia-material from the localities of Almenara 1 (= Casablanca 1) and Galera 2 (Guadix-Baza Basin). This revision led to the recognition of a new species, Kislangia gusii, distinguished from the Central European K. rex, to which most of the Spanish populations were referred until now. Two different lineages of Kislangia existed during the late Villanyian in Europe, one leading to K. gusii and the other one leading to K. rex. K. gusii is compared with other samples, from French and Spanish localities.

Dissociated skeletal elements of bourgueticrinid crinoids, comprising mostly columnals, radicular cirri, a few cups and some brachials, are recorded from Turonian-Maastrichtian strata of southern Poland (Miechów Trough, Kraków-Cze˛stochowa Upland, Holy Cross Mountains and Opole Trough). Published records of bourgueticrinids from Poland are surprisingly few; only specifically indeterminate columnals, radicular cirri and a sole proximale, plus a single cup of Bourgueticrinus utriculatus have been noted. The present material, although limited, clearly demonstrates that these crinoids must have been less rare than anticipated and are, in fact, distributed throughout the entire Upper Cretaceous sequence in this area. The majority of bourgueticrinids had an...

Two new brachyuran species are described for the Upper Cretaceous Mexcala Formation, Guerrero State, Mexico. Longusorbis quadratus new species (Coniacian, Temalac region) is the oldest and southernmost record for the genus. Xanthosia zoquiapensis new species (Campanian, Zoquiapa region) is the first record for the genus in Mexico. In addition, the age for Costacopluma bishopi Vega and Feldmann is discussed (Coniacian, Temalac region) and represents the oldest and southernmost record for Cretaceous representatives of this genus in North America. All specimens are considerably smaller compared to other species of the same genera and are interpreted as the first example of brachyuran dwarfism in the geological record. These species add new insight into...

A small lot of latest Cretaceous brittlestars from the Maastrichtian type area, contained in the Binkhorst [van den Binkhorst] Collection at the Museum für Naturkunde in Berlin, is restudied and, in part, illustrated for the first time. Presumably, these thirteen specimens represent only a portion of the ophiuroid material referred to in two papers by Binkhorst van den Binkhorst, both published in 1859, because all are assignable to two species which are common only in the Nekum and Meerssen members of the type Maastrichtian, namely Felderophiura vanderhami Jagt, 1991, and Ophiomusium lux Jagt & Kutscher in Jagt, 2000. Brittlestar material from lower levels within the Maastricht Formation (i.e., Valkenburg, Gronsveld, Schiepersberg and Emael members)...

All Campanian, Maastrichtian and Danian echinoids known to date from the extended type area of the Maastrichtian Stage are listed and, with a few exceptions, also illustrated. The geographic and stratigraphic distribution of these echinoderms are documented. A total of 55 (sub)genera and 119 (sub)species (inclusive of formae), two of which are new, are recognised. A number of taxa are reassigned, while others have to remain in open nomenclature for the time being. Recorded for the first time from the area are representatives of Hagenowia and Zeuglopleurus, as well as juvenile specimens of Hemipneustes striatoradiatus. Cidaris gigas (= Temnocidaris (Stereocidaris) gigas) is accepted as a valid species. The name Cyphosoma rutoti is shown to be based on the...

The palaeobiology of echinoderms occurring in the Meerssen and Geulhem members is discussed and changes in diversity across the K/T boundary are documented. Using literature data on the ecology of extant faunas, the various echinoderm groups are considered. Naturally, such data can only be applied with due caution to fossil forms, whose skeletal morphology is often incompletely known. This holds especially true for asteroids, ophiuroids, and crinoids, which, upon death, rapidly disintegrate into jumbles of dissociated ossicles. Bioturbation, scavenging, and current winnowing all contribute to blurring the picture still further. However, data on extant forms do allow a preliminary subdivision of fossil species into various ecological groups, which are...

Amler, M.R.W..

During a field trip to the Peña-Corada Unit of the southernmost Esla region of the Cantabrian Mountains in 1927, the German stratigrapher Wilhelm Kegel sampled brachiopods and bivalves from a section in the Laoz valley near La Ercina. The stratigraphic position is believed to be part of the Nocedo Formation of Frasnian age. This fauna includes poorly preserved steinkerns of a near-shore bivalve fauna that was prepared for publication including labels and proposed names, but never published. The fauna represents only a very small and random part of the former community. But as information on Frasnian bivalves is scarce, the few specimens add important information on the distribution and palaeogeographic occurrence of near-shore, that is, Rhenish Facies...

Two rather small mollusc faunas, collected nearly seventy years ago by L. M. R. Rutten, have been examined. Though fairly close together and presumably not much different in age (Preangerian: Tf3), they show no relationship to one another. Tapian Langsat: this locality yielded 11 species all of which occur in Preangerian deposits, particularly in the basal Menkrawit and Gelingseh Beds of the Sangkulirang/Mangkalihat area much farther to the North, there being but a solitary species in common with the classical Javanese Preangerian. Gunung Batuta: consisting of 13 species, this assemblage has, like the corals from the same locality but unlike Tapian Langsat, a number of species (in this case 8) in common with the classical Preangerian, while the...

Late Silurian fish microfossils from Klinta and Rinnebäcks Bro (Scania, south Sweden), with remarks on the morphology of Nostolepis striata trunk scales

Vergoossen, J.M.J..

The microvertebrate faunas from ten small pieces of rock from the Öved Sandstone Formation at Klinta (1-10) yielded osteostracan, heterostracan, thelodont, and acanthodian remains, dated here as Whitcliffian. The most important age indicators are the heterostracan Archegonaspis and the thelodont zonal fossil Thelodus sculptilis. The latter taxon is also present in a small Whitcliffian fauna from the Öved Sandstone Formation at Rinnebäcks bro, together with other thelodont and acanthodian remains. From Rinnebäcks bro no previous records of Silurian fish fossils exist. In an attempt to gain a better understanding of nostolepid trunk scale variation and to develop an instrument to assess this variation, seven Nostolepis striata trunk scales from Klinta are...

Vergoossen, J.M.J..

The microvertebrate assemblages from Ramsåsa sites D and ‘south of church’, Skåne, south Sweden are described for the first time. Analysis of these microvertebrate assemblages from the Öved Sandstone Formation of Skåne indicates a Ludlow rather than Pridoli age. One of two faunas from Ramsåsa site D contained the zonal fossil Thelodus sculptilis and the other T. sculptilis in association with Paralogania ludlowiensis and Thelodus carinatus. The presence of T. carinatus is the youngest record of this species in Laurussia, and indicative of the transitional phase between the Andreolepis hedei and T. sculptilis Zones of the East Baltic Microvertebrate Standard. A fauna with Thelodus parvidens, from south of Ramsåsa church, proved only broadly datable as...

In this first part of a revision of the Cricetidae from Vieux-Collonges (Rhône, France) the genus Cricetodon is dealt with. This genus is represented by three species, C. meini Freudenthal, 1963, C. aureus n. sp. and a third one which is not named, because it is based on one specimen only. Each of these species represents a separate evolutionary lineage.

Apart from the common cricetid fauna, the site of Vieux-Collonges contains a number of rare forms: Lartetomys, Melissiodon, Neocometes, and Anomalomys. This scarce material is described and compared with material from other European localities. The stratigraphie position of Vieux-Collonges is discussed briefly. En plus des Cricetodontinae et Cricetinae communs, il existe à Vieux-Collonges plusieures espèces d'autres groupes de Cricetidae, représentées par des matériaux peu nombreux. Il s'agit de Lartetomys mirabilis, Lartetomys zapfei, Melissiodon aff. dominans, Neocometes similis et Anomalomys sp. Cettes formes sont décrites, et leur valeur pour la corrélation de Vieux-Collonges avec d'autres gisements de mammifères miocènes est discutée.

The revision of the fish fauna from the Tiglian of Tegelen (The Netherlands) allows the improvement of our knowledge of this fossilbearing locality. Eleven genera of freshwater fishes have been recognized. Their association enables one to define the deposition conditions under which the clayey sands were deposited in the upper part of the Tiglian Stage. It is clearly shown that these deposits have been laid down by slowly moving waters. The climate does not appear to have been strikingly different from the recent one of The Netherlands. La revision de l'ichthyofaune tiglienne de Tegelen (Pays-Bas) permet d'approfondir les connaissances relatives à ce gisement. Onze genres actuels de Poissons d'eau douce ont été identifies. Leur association permet de...
