The 1 m thick intercalated marly sediments of Entrischenbrunn represent a floodplain pond within a braided fluvial system of late Langhian age. The organic rich upper part of the marls that are characterized by the presence of numerous plant macrofossils, are investigated for palynomorphs with SEM. The results reveal that many typical azonal broad...

The Burtenbach sand pit, about halfway between Ulm and Augsburg, is one of the most productive sites for fossil plants in the Molasse zone. It was placed in the mammal zone MN 5 on the basis of the numerous animal remains. Lithostratigraphically dated to about 15.3 +/- 0.1 million years as part of the Lower Fluviatile Series, it is characterized by...

The approximately 900 plant fossils of the collection of the inatura Erlebnis Naturschau GmbH in Dornbirn (Natural History Muse­ um) originate from about 20 sites in the Folded (Subalpine) and Foreland Molasse of northwestern Vorarlberg. After a first minor publication by K räusel in 1930, a revision of the entire collection is now presented. The m...

A critical review of reports from European localities reveals that the herein newly described Populus erratica Sachse, nom. nov. was previously treated under a variety of names. Due to its stratigraphical range from the late Oligocene to early Miocene, it might be a useful tool for age determinations in the terrestrial record. So far it is known on...

Abstract For a short time in the gravel pit Unterzolling (KRONTHALER Kies) in the north from Freising a leaf bearing marl lense was exposed in the „Middle Series“ of the „Upper Freshwater Molasse“ (OSM). About 100 leaf impressions belonging to 20 species were identified. The composition indicates a hardwood floodplain forest bordering a little lake...

The gravel pit Unterwohlbach near Hohenkammer (Lkrs. Freising) is one of the most important fossil sites in the sediments of the Upper Freshwater Molasse in Bavaria. Not only the rich leaf-flora, found in the upper marly horizon is unique, but also the second in a lower marly horizon with another composition. In this way we have, together with faun...

For the first time this extraordinary divers collection yielding about 3200 identified leaf remains assigned to more than 100 species owned by the Naturmuseum of the city of Augsburg is presented in detail. It represents a typical Miocene alluvial forest vegetation in the Bavarian Upper Freshwater Molasse basin, dominated by poplar (Populus balsamo...
Article
Zusammenfassung Koprolithen aus der eozänen Braunkohle von Stolzenbach (Hessen) werden hier beschrieben und mit weiteren Kotballen aus dem Eozän (Eckfelder Maar, Eifel) sowie denen rezenter Breitschnauzenkaimane verglichen. In Anlehnung an ein Klassifikationsschema von SCHMIDT (1991) können die meisten Kotballen aus Stolzenbach mit Krokodilen in Ve...
Article
Coproliths from Eocene browncoals from the mine Stolzenbach (Hessen) are under research. We assume different types of fossils: large coproliths from crocodiles, small ones from fishes and a possible gastrolith (crocodile) as a strange element in the lignite.
Article
A new fossil site in Bavaria (Miocene) yield leaves, diaspores and molluscs from Upper Freshwater Molasse sediments. The blueish-greyish marls and clays, intercalated in Northern “heavy gravels” (Nordliche Vollschotter) are dominated by Daphnogene-leaves and Trapa/Hemitrapa-fruits.

Die durch den Übergang von den fluviatilen Pechelbronn-Schichten zu den marinen Foraminiferenmergeln charakterisierte niedrig-energetische Transgres- sion wird sedimentologisch und palynologisch an einem Bohrkern aus dem Ölfeld Eich/Königsgarten dokumentiert. Ein eigens entwickeltes Schema erfasst Palyno- morphe, strukturierten und strukturlosen or...

Der Zuckerberg in Ennepetal ist ein typischer Berg des nordwestlichen Sauerlandes, aufgebaut aus mitteldevonischen Silt- und Sandsteinen sowie eingelagertem verkarstetem Riffkalkstein mit Höhlen, wasserlosen Tälern, einer Doline und einem Schluckloch. Ein kürzlich wieder freigelegter historischer Steinbruch zeigt anschaulich die Schichtenfolge und...

The distal part of a mass flow deposit has been excavated across an area of 400 m2 in the basinal facies of the Eckfeld Maar. The high concentration and diversity of fossils in mainly excellent preservation (i.e. leaves, fruits/seeds, wood, molluscs, vertebrate teeth, and bones such as undeformed sculls) is unique and underline its outstanding impo...

By using cuticular analysis for the first time laurophyllous leaf remains from the European Tertiary have been reliably identified as belonging to the Oleaceae. Despite ecologically determined variation in cuticular structures, Late Miocene leaf material from northern Italy is assigned to a single species, Oleinites liguricus Sachse n. sp. The asso...

The combined interpretation of marine and terrigeneous macro- and microfossils from the marine Late Miocene Makrilia Formation near Ierapetra, south-eastern Crete was used for the reconstruction of the palaeoenvitonments and palaeoclimatic conditions. The continental derived material in this near shore environment includes leaves, fruits/seeds and...

This paper describes a megaflora, preserved as impressions, and a micro-flora from the Tortonian flysch sediments (about 7-8 M.a.) of south-eastern Crete. The megaflora consists of over 500 leaf, fruit, seed and petal remains, representing about 70 equisetalean, gymnosperm and angiosperm taxa. About half allow themselves to be identified at least a...

Question
Hi, this plant impression with a remarkable nervature was found in 15 Million year old sediments of the Bavarian Molasse Basin. Can somebody help to identify it? Remarkable is the strong petiole and the lobed secondary veins branching in nearly right angle. Length is appr. 2 cm.
Thanks a lot Markus
Question
In a Miocene sand quarrel of Bavaria I found some compound leaves, where the distal leaflet of an alternating arranged compound leaf seems not to arise from the petiole but from the midrib within or at the base of the bigger terminal leaflet. Its blade is asymmetrically reduced on this side. Leaf margin has spiny little teeth.
If it would be just one indiviudal, I would think: just overlapping of different leaves, but there are several and allways they seem to be connected.
Does anybody know, in which extant plant group such construction might be present?
Question
They were found at ancient fire places, where sand dunes have moved away. To me they seem to be neolithic.
