Lithofacies and ichnofacies of turbidite deposits, West Java, Indonesia

Budi Muljana, Undang Mardiana, Adi Hardiyono, Nana Sulaksana, Djadjang Jedi Setiadi, Lia Jurnaliah, Nurdrajat

This study focuses on the analysis of sedimentary facies and ichnogenus variations to determine the palaeogeographic setting of turbidite deposits that are clearly exposed in the surroundings of Majalengka area, West Java, Indonesia. Lithofacies variation in turbidite deposits, identified from…

Why Lycospora dominated many Pennsylvanian spore assemblages

Barry A. Thomas

The microspore genus Lycospora in its wider sense is produced by both heterosporous cones, Flemingites, and homosporous cones Lepidostrobus. Calculations are made of the number of microspores that are produced by cones and then by individual Pennsylvannian arborescent lycophytes. The distribution of…

Early complex tiering pattern: Upper Ordovician, Barrandian area, the Czech Republic

Pavel Bokr, Radek Mikuláš, Petr Budil, Petr Kraft

Upper Ordovician shallow marine fine-grained sandstones and siltstones exposed in the Loděnice – vinice locality yielded a distinct and well-preserved tiering pattern of trace fossils. The two uppermost tiers are composed mainly of Bifungites and Nereites. Deeper in the sediment, tiers dominated by…

Hidden treasures uncovered: successful detection of fossils below the surface in large limestone blocks using a standard medical X-ray CT scanner

Miguel Prôa, Daniel Pouit, Thomas Rouillard, Peggy Vincent, Benoît Mellier

The use of CT scans in palaeontology has a long history. Most X-ray CT scans of fossils are carried out on previously prepared specimens and seldom on unprepared blocks of fossils. Here we report the use of a standard medical X-ray CT scanner to detect vertebrate and invertebrate fossils inside…

First record of intact equisetalean strobili from the Wealden (Lower Cretaceous) of the Isle of Wight, southern England

Christian Pott

Two excellently preserved small strobili were obtained from a Wealden plant debris bed in the Lower Cretaceous (Barremian) Wessex Formation, south-east of Chilton Chine, on the Isle of Wight, southern England. The strobili are preserved as compressions and show the characteristic morphology of…

Baragwanathia brevifolioides, a nomen novum for B. brevifolia P.Kraft et Kvaček, 2017

Petr Kraft, Zlatko Kvaček

Baragwanathia brevifolioides is established as a nomen novum for B. brevifolia P.Kraft et Kvaček, 2017, recently described from the Silurian of the Prague Basin, Czech Republic and revealed as a later homonym of B. brevifolia Hundt, 1952.

The ultrastructure of the tooth enamel of small Equus of the “tarpan” group and their possible phylogenetic connections

Vitalii Demeshkant, Leonid Rekovets

The paper presents the results of a comparative analysis of the ultrastructure of tooth enamel (incisors, premolars and molars) in representatives of morphologically (and possibly phylogenetically) similar forms of small horses. These are both extinct forms of tarpan – Equus gmelini from various…

Actinopterygians of the Broumov Formation (Permian) in the Czech part of the Intra-Sudetic Basin (the Czech Republic)

Stanislav Štamberg

Actinopterygians from the Permian sediments of the Czech part of Intra-Sudetic Basin, occurring in the Ruprechtice and Otovice Limestone horizons (Broumov Formation), are revised and redescribed based on both old material and newly discovered specimens. A new diagnosis and reconstruction of…

New leaf species from the upper Miocene flora of the leaf-bearing Wischgrund clay (Lower Lusatia, Brandenburg, Germany)

Ursula Striegler

This is a brief outline of the fossil content of the Wischgrund leaf-bearing clay (Lower Lusatia, Brandenburg State, Germany), which belongs to the youngest Neogene layers of Lower Lusatia (upper Miocene, Tortonian). It is a deciduous temperate flora, with a small proportion of evergreen species.…

New suoid fossils (Mammalia, Artiodactyla) from the Miocene of Moghara, Egypt, and Gebel Zelten, Libya: biochronological implications

Martin Pickford, Mohamed Abdel Gawad, Mohamed Hamdan, Ahmed N. El-Barkooky, Mohammed H. Al Riaydh

Some undescribed suoid specimens from early and middle Miocene deposits at Moghara, Egypt, and Gebel Zelten, Libya, are of interest for biochronology. The fossils comprise maxillae and mandibles with incomplete dentitions, which are described and illustrated in detail. Three species of suids and one…

The Amphicyoninae (Amphicyonidae, Carnivora, Mammalia) of the early Miocene from Tuchořice, the Czech Republic

Jorge Morales, Oldřich Fejfar, Elmar Heizmann, Jan Wagner, Alberto Valenciano, Juan Abella

The Amphicyoninae of the early Miocene from the locality of Tuchořice, the Czech Republic, are represented by three species. Two of them are classified within the tribe Amphicyonini: Paludocyon bohemicus (Schlosser, 1899) as the type species of Paludocyon n. gen., and a large-sized amphicyonid…

New actinopterygians from the Permian of the Brive Basin, and the ichthyofaunas of the French Massif Central

Stanislav Štamberg, Jean-Sébastien Steyer

A new actinopterygian fauna from the Permian of the Brive Basin (Corrèze, Massif Central, France) is described in detail. It is represented by a new pygopterid taxon, Briveichthys chantepieorum gen. et sp. nov., erected and described here on the basis of several well-preserved specimens showing…

Naming of parts: the use of fossil-taxa in palaeobotany

Christopher J. Cleal, Barry A. Thomas

Fossil plants are extinct plants whose remains (referred to as plant fossils) are found preserved in sedimentary deposits. Plant fossils are classified using fossil-taxa as defined in the International Code of Nomenclature. Fossil-taxa differ conceptually from taxa of living plants in that they…

Stratigraphy, chronology and palaeontology of the Tertiary rocks of the Cheringoma Plateau, Mozambique

Marion Bamford, Martin Pickford

The discovery of fossil plants, marine molluscs and mammals in the Mazamba Formation, Cheringoma Plateau, Mozambique, opens a new chapter in the study of this part of the African Rift System. The evidence suggests that the Mazamba Formation is older than previously reported, probably late Eocene…
