The campanulary-ventral-sporal micromorphology of the best preserved structure of these compares sufficiently well with previously reported structures from the Sydney Coalfield named Potoniea krisiae. Earlier studies involving larger sampling suites furthermore contributed to the observation that Hexagonocarpus sp. (female organ) and P. krisiae (male organ) usually co-occur with abscised L. obliqua pinnules; however, these two organs do not co-occur on isochronous bedding planes. In the absence of confirmatory organic attachments, the presented data provide as yet the strongest support for the hypothesis of the organs’ connectivity, but whether female-male trees existed or not, and the mode of attachment of the organs remain unknown. Hypothesized for the latter is pinnate attachment.","PeriodicalId":12284,"journal":{"name":"Folia Musei rerum naturalium Bohemiae occidentalis.

Specimens contain elliptical or rounded pads situating at the swollen tip of pinnule lobe tendrils which are highly comparable to those of the extant Parthenocissus tricuspidata in the way that both of them are similar in form and function. Specifically, information we have gained suggested that pteridosperms from the Permian might have performed a similar type of physiological process by producing some chemical substances which assisted them in climbing. The Wuda pteridosperm likely to climbed on Cordaites or Sigillaria trees. Moreover, physical principles such as the pressure difference between inside and outside of the pads also seems to play an important role in assisting climbing. The new finding indicates that some pteridosperms in the Permian Cathaysian flora possessed climbing growth habit as well as those in the Late Carboniferous Euramerica Flora, where climbing/scrambling growth habit is well known in the coal swamp forests. This finding shows one of the several earliest climbing habits in Cathaysia Flora and thus remarkably promotes our understanding of the growth habit of pteridosperm and the change in plant community structure in that area.","PeriodicalId":12284,"journal":{"name":"Folia Musei rerum naturalium Bohemiae occidentalis.

Unequivocal sclerites were observed in limestones of Emsian to late Eifelian age in six localities of the Barrandian area of the Central Bohemia of the Czech Republic. Formerly observed size and shape variations of Eurytholia sclerites prevent formal description of a new species on few specimens of Emsian and Eifelian age. Therefore the new specimens are identified as Eurytholia aff. bohemica. Their presence indicates longer time range of the Eurytholia animal, covering not only the Ordovician, the Silurian and the earliest Devonian as known formerly, but also late Lower Devonian and the Middle Devonian. Similar features in morphology and histology of Eurytholia indicate relationship to a conodont Pseudooneotodus and a support suggestion about the vertebrate origin of Eurytholia sclerites.","PeriodicalId":12284,"journal":{"name":"Folia Musei rerum naturalium Bohemiae occidentalis.

Most of these sites have not been previously precisely localized. Our investigation is focused mainly on so-called “Špinar’s localities” named after Prof. Z. Špinar and described in his work. Several sites were also described by A. Stehlík, J. Zajíc & S. Štamberg and J. Augusta. The reason for the localization of these locations is that more than 3,000 samples from these sites are stored at the Chlupáč’s Museum of Earth History of the Charles University in Prague. Most localities are situated around the village of Bačov, where carbonization is the dominant type of preservation of Palaeozoic amphibian skeletons.","PeriodicalId":12284,"journal":{"name":"Folia Musei rerum naturalium Bohemiae occidentalis.

This is demonstrated for cuticles from “Pecopteris” polypodioides of the coal basins in the Czech Republic and Canada. “Pecopteris” polypodioides is a marattialean tree fern which was part of the peat-forming flora, growing in a wet environment. Due to this fact, cuticles are generally very thin, and we assume that their major function was to reduce the ability of fungal spores to germinate and bacterial to grow, thereby reducing the possibility of these agents to cause disease. The secondary function was to be a major barrier to water loss and reducing the wettability of pinnules.","PeriodicalId":12284,"journal":{"name":"Folia Musei rerum naturalium Bohemiae occidentalis.

Recovered were soluble and insoluble, black, round and flat, opaque or translucent rodlets that are up to 5 mm long and ca. 10-111 μm wide, and are typed as (i) transparent, (ii) insoluble, or (iii) soluble in Schulze’s solution. In situ insoluble rodlets can be distinguished from associate coal and cuticle-free compression foliage and rachides by relatively high aromaticity and low aliphatics, although their chemical composition is unknown.
