Problematic Sclerites Eurytholia from the Lower and Middle Devonian of the Czech Republic

Publicado en línea: 27 Jul 2020
Páginas: 1 - 11

Resumen

Abstract

Problematic phosphatic sclerites Eurytholia are reported for the first time from the Middle Devonian. 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.

State of the Art of “Amphibian” Localities of the Letovice Subbasin (Boskovice Basin, Czech Republic)

Publicado en línea: 27 Jul 2020
Páginas: 13 - 24

Resumen

Abstract

This paper provides a summary of localization of Permian historical sites in the Boskovice Basin, which yielded amphibians of the family Discosauriscidae. 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.
