A land micro-mammal fauna from the Early Eocene marine Egem deposits (NP12, Belgium) and the first occurrence of the peradectid marsupial Armintodelphys outside North America
-
Dental remains of land mammals are sometimes discovered in shallow marine Paleogene deposits of the North Sea Basin. Such is the case for eleven specimens we describe here from the Early Eocene Egemkapel Clay Member in the middle part of the Tielt Formation, found in Ampe quarry at Egem in Northwestern Belgium. The small fauna consists of 6 taxa, including the neoplagiaulacid multituberculate Ectypodus, the erinaceomorph insectivore Macrocranion, the nyctitheriid Leptacodon, an eochiropteran bat possibly belonging to a palaeochiropterygid, an unidentified perissodactyl possibly belonging to an equoid, and a new species of the peradectid marsupial Armintodelphys. The latter represents the first European occurrence of the genus, which was previously only known from the North American late Early and early Middle Eocene of the Wind River and Green River basins in Wyoming and the Uinta Basin in Utah. Biogeographic and biostratigraphic analyses of peradectid marsupials suggest that Armintodelphys dispersed between North America and Europe around the time of the Early Eocene Climatic Optimum. The Egemkapel Clay Member has been dated as middle NP12, early late Ypresian, whereas the Egem mammal fauna can be correlated to the fauna of Avenay from the Paris Basin, which is the international reference-level MP8+9 of the mammalian biochronological scale for the European Paleogene.

Dispersals of placental carnivorous mammals (Carnivoramorpha, Oxyaenodonta & Hyaenodontida) near the Paleocene-Eocene boundary: a climatic and almost worldwide story
-
During the Late Paleocene and around the Paleocene-Eocene boundary, there were important mammalian dispersals in Laurasia involving earliest modern mammals such as rodents, primates, perissodactyls, and artiodactyls. The placental carnivorous mammals (Viverravidae, “Miacidae”, Hyaenodontida, Oxyaenodonta) importantly took part in these dispersals. The present article shows that these latter mammals allow reconstructing faunal dispersal scenarios during the early Paleogene. Indeed, they evidenced several dispersal ways among Laurasia, but also with Africa and possibly India. The dispersal phases discussed in the present paper concern the Early Paleocene, Late Paleocene, latest Paleocene (Clarkforkian NALMA), and Paleocene-Eocene transition.

First Early Hominin from Central Africa (Ishango, Democratic Republic of Congo)
-
Despite uncontested evidence for fossils belonging to the early hominin genus Australopithecus in East Africa from at least 4.2 million years ago (Ma), and from Chad by 3.5 Ma, thus far there has been no convincing evidence of Australopithecus, Paranthropus or early Homo from the western (Albertine) branch of the Rift Valley. Here we report the discovery of an isolated upper molar (\#Ish25) from the Western Rift Valley site of Ishango in Central Africa in a derived context, overlying beds dated to between ca. 2.6 to 2.0 Ma. We used µCT imaging to compare its external and internal macro-morphology to upper molars of australopiths, and fossil and recent Homo. We show that the size and shape of the enamel-dentine junction (EDJ) surface discriminate between Plio-Pleistocene and post-Lower Pleistocene hominins, and that the Ishango molar clusters with australopiths and early Homo from East and southern Africa. A reassessment of the archaeological context of the specimen is consistent with the morphological evidence and suggest that early hominins were occupying this region by at least 2 Ma.

New lissamphibians and squamates from the Maastrichtian (Late Cretaceous) of the Haţeg Basin (Romania)
-
Numerous remains of amphibians and squamates were discovered in the continental sediments of theMaastrichtian Sânpetru Formation, south of Pui Village (Haţeg Basin, western Romania). The lissamphibians are represented by a salamander−like allocaudatan (Albanerpeton sp.) and at least two discoglossid frogs (cf. Eodiscoglossus sp. and cf. Paradiscoglossus sp.). The numerous lizards are represented by, e.g., the teiid Bicuspidon hatzegiensis sp. nov., and for the first time in a Late Cretaceous site, by two species of the paramacellodid Becklesius (Becklesius nopcsai sp. nov. and Becklesius cf. B. hoffstetteri). Snakes are also present in this site by an indeterminante madtsoiid, which represents the first occurrence of this family in eastern Europe. The presence of Albanerpeton in this site confirms that this genus appeared in Europe by at least the Late Cretaceous instead of Miocene as previously thought. The presence of both Albanerpeton and Bicuspidon in Haţeg Basin suggests a North American influence on eastern European amphibian and lacertilian faunas by Maastrichtian times.

Devonian antiarch placoderms from Belgium revisited
-
Anatomical, systematic, and paleobiogeographical data on the Devonian antiarchs from Belgium are reviewed, updated and completed thanks to new data from the field and re-examination of paleontological collections. The material of Bothriolepis lohesti Leriche, 1931 is enhanced and the species better described. An undetermined species of Bothriolepis is recorded from the Famennian of Modave (Liège Province), one species of Asterolepis redescribed from the Givetian of Hingeon and another one described from the Givetian of Mazy (Namur Province). Grossilepis rikiki sp. nov. is recorded from the Famennian tetrapod-bearing locality of Strud (Namur Province) and from the Famennian of Moresnet (Liège Province). It is the first occurrence of Grossilepis after the Frasnian and on the central southern coast of the Euramerican continent. Its occurrence in the Famennian of Belgium may be the result of a late arrival from the Moscow Platform and the Baltic Depression, where the genus is known from Frasnian deposits. Remigolepis durnalensis sp. nov. is described from the Famennian of Spontin near Durnal (Namur Province). Except for the doubtful occurrence of Remigolepis sp. in Scotland, this is the first record of this genus in Western Europe. Its occurrence in Belgium reinforces the strong faunal affinities between Belgium and East Greenland and the hypothesis of a hydrographical link between the two areas during the Late Devonian.
