During the Late Eocene two marine provinces existed in the epicontinental Europe: a West European province with a warm water foraminiferal fauna of Tethyan character and an East European province with a cold water fauna. The boundary between these provinces was situated in Poland. The main dispersion routes of the Late Eocene foraminiferal faunas coincide with some important tectonic features.

Cheloniellon calmani Broili 1932, is restudied with the aid of the radio-graphic technique applied to the two well known specimens (CI and CII), and also two other specimens (CIII and B).Bundenbachiellus giganteus (B) (Broili 1929) is probably a synonym, but the incomplete and distorted condition makes it appear expedient to consider this name as a nomen nudum. New radiographs of CI, CII and CIII allow a better reconstruction of C.calmani than the one based on the distorted specimen CI. The new picture shows a head with two tergite plates on the dorsal side and one pair of antennae, a second preoral pair of appendages and four pairs of probably uniramous legs with gnathobases on the ventral side. Only the last pair is situated beneath the second tergite. The body has eight tergites with wide pleura corresponding to eight pairs of biramous appendages. The outer branch carries very stout lamellar spines. The ninth tergite is small and cylindrical and corresponds to long furcal rami. The posterior end is probably formed by a conical piece, possibly a telson, without appendages.Cheloniellon was a benthic carnivore. The second preoral appendages and postoral gnathobases make it unexpectedly similar to eurypterids and xiphosurids, and it may be a late representative of a group of trilobitomorphs that gave rise to the Chelicerata.

In 1907, R. Markgraf made a small collection of Oligocene fossil primates from Egypt for the Staatliches Museum für Naturkunde in Stuttgart. Circumstances of discovery suggest that this collection came from the same stratigraphic horizon (the Upper Fossil Wood zone) and possibly the same locality as a similar collection made earlier that year byMarkgraf for the American Museum of Natural History in New York. Three new genera and species were described bySchlosser, based on the Stuttgart collection.Parapithecus fraasiSchlosser is a junior synonym ofApidium phiomenseOsborn. “Parapithecus“grangeriSimons is placed in the new genusSimonsius. Propliopithecus haeckeliSchlosser andMoeripithecus markgrafiSchlosser have previously been recognized as synonyms. In addition,Aegyptopithecus zeuxisSimons is known from the Upper Fossil Wood zone.

ZusammenfassungIn mehreren Fundorten Mittelsloweniens, NW Jugoslawien, sind ladinische (Mitteltrias) Conodonten-clusters des Skelettapparates vonPseudofurnishius murcianus gefunden worden:Pseudofurnishius murcianus als Plattform-Element (P-Element), enantiognathi-forme, hindeodelliforme, prioniodiniforme und pollognathiforme Elemente bilden single taxon clusters, P-Element, enantiognathiforme, hibbardelliforme, hindeodelliforme, pollognathiforme und prioniodiniforme Elemente dagegen multitaxon clusters. Es wurden bis jetzt77 single taxon clusters und 15 multitaxon clusters gefunden.

In fabrosaurids the upper jaw is flat and the lower jaw is slender so the ’cheek’ teeth are marginal and not inset as is the case in all other ornithischian dinosaurs. The ’cheek’ teeth of fabrosaurids have anteroposteriorly expanded crowns but lack wear surfaces formed by tooth to tooth contact. Two genera are recognized from the Triassic-Jurassic boundary of Lesotho with good material previously referred toFabrosaurus as a new genus that represents the most conservative ornithopod described to date. The anatomy ofNanosaurus (Upper Jurassic, U.S.A.) andEchinodon (Jurassic-Cretaceous boundary, England) is redescribed; in both genera the tooth bearing bone of the lower jaw is deepened posteriorly and inEchinodon there is a true canine tooth in the upper jaw.
