Satisfactory State

In the Geological Department of the British Museum (Natural History) are preserved a certain number of slabs from Oeningen, exhibiting skeletons of Rodents. Partly owing to unskilful developing, partly to the absence of the counterpart-slab, several of them are in such a crushed and otherwise imperfect condition, that in some cases not even the genus could be made out with certainty; which is equivalent to saying that their interest is little beyond that of mere curiosities. On closer examination it appeared to me that in some instances the case was not quite so hopeless, and that by carefully developing the more important parts still concealed by the matrix, a more satisfactory state of things might be obtained. The following pages are an account of the result arrived at.

Collection Sites

Testudo antiqua is one of the few fossil turtle names to have survived the past 200 years of taxonomic reshuffling with its original genus and specific epithet intact. The nine currently known specimens were collected from the middle Miocene Hohenhöwen locality in southern Germany. Because the available Hohenhöwen material was never fully described, we here completely document all known specimens. It is unclear which of these specimens formed the original T. antiqua type series, so we herein selected the best preserved representative as the neotype. A phylogenetic analysis places T. antiqua in a basal polytomy within the clade Testudo, indicating that T. antiqua may represent the ancestral morphology of Testudo. As with a number of other published studies, ours was unable to resolve relationships between the three extant Testudo lineages (the hermanni-group, the graeca/kleinmanni/marginata group, and the horsfieldii-group). Finally, with a view toward locating more turtles and in order to better understand the geological and ecological context of these tortoises, we visited Hohenhöwen several times to search for the original collection sites, but we were unable to locate the original fossil quarries described in the literature.

Abstract Fossil bats are described from the karstic deposits of the Erkertshofen 1, Erkertshofen 2 and Petersbuch 2 sites in eastern Bavaria, southern Germany (MN 4). Fossils are discussed with regard to taxonomic, stratigraphic and palaeoecologic significance. The rich fossil material represents at least 12 different bat species belonging to Megadermatidae, Rhinolophidae and Vespertilionidae. The syntopic appearance of four different rhinolophids is demonstrated for the first time for the Neogene bat assemblages of Europe. The remains of Rhinolophidae and Vespertilionidae are the most numerous, of which the proportion of typically early Miocene species Rhinolophus aff. lemanensis, R. dehmi, Hanakia agadjaniani and Miostrellus cf. petersbuchensis are significant. However, there are also remains of R. cf. delphinensis, M. cf. noctuloides, Plecotus cf. atavus and H. aff. antiquus, which are characteristic of the younger middle Miocene faunas of Central Europe. Analysis of the composition of the bat fauna has allowed biostratigraphic correlation of the studied faunas to be estimated at a number of other early Miocene localities in Europe.

Dental Anomaly

The maxillary presented in this work has been excavated in the middle Miocene karst filling Petersbuch 136 (Germany, Bavaria) and shows the oldest evidence of dental anomaly in a sciurid. The aberrant morphology, probably hyperdontia or no replacement of roots of deciduous teeth, affects the area of the P3, a tooth that is generally not well documented in the Spermophilinus record.

ABSTRACT Formation of the Central European tektites, known as moldavites, has been associated with a large meteorite impact in southern Germany 14.8 m.y. ago. The geochemical link between moldavites and their source materials, and the processes of their possible chemical differentiation still remain uncertain. Some differences in chemical composition between moldavites and sediments of corresponding age from the surroundings of the Ries crater could be explained by a hypothesis according to which biomass covering the pre-impact area contributed to the source materials. In a comparison of the geochemical compositions of a large representative set of moldavites and suitable Ries sediments, enrichment in elements K, Ca, Mg, and Mn and depletion of Na in moldavites, similar to redistribution of these elements during their transfer from soil to plants, could indicate the unconventional biogenic component in moldavite source materials. Simple mixing calculations of the most suitable Ries sediments and a model biogenic component represented by burned biomass residue are presented. The plausibility of the estimated biomass contribution considering reconstructions of the middle Miocene paleoenvironment in the pre-impact Ries area is discussed. No significant vapor fractionation is required to explain the observed variability of moldavite chemical composition.
