Complementary Description of the Middle Ordovician Trilobite Associations at Praha-Vokovice

Pubblicato online: 19 Jan 2016
Pagine: 1 - 7

Astratto

Abstract

The temporarily exposed rocks of the Dobrotivá Formation (Middle Ordovician, upper Darriwilian) accessible, due to lower water levels, in Džbán water reservoir (Praha-Vokovice area) have produced common fauna. The newly obtained trilobite-dominated fossil associations enable a more detailed discussion of faunal changes in the lower and lower-middle portions of the Dobrotivá Formation - a transition from the Placoparia Association to the newly recognized Degamella-Zeliszkella Association, dominated by mesopelagic forms.

Fenestrate Bryozoans in the Acanthopyge Limestone (Eifelian) in the Barrandian Area (Czech Republic)

Pubblicato online: 19 Jan 2016
Pagine: 9 - 15

Astratto

Abstract

The first occurrence of fenestrate bryozoans is reported from the Acanthopyge Limestone (Eifelian) in the Koněprusy area of the Czech Republic. Fragmented zoaria have been identified in lightgrey crinoidal-limestone rich with brachiopods, corals, and stromatoporoids. Several species of fenestrates are evident, but poor preservation and fragmentation of zoaria allow only approximate taxonomic determination. The fenestrates, Fenestella sp., Laxifenestella (?) sp., Hemitrypa sp., Polyporella sp., Ptylopora sp., and Reteporina sp., are illustrated and briefly described. The presence of fenestrates has a great palaeoenvironmental significance. Fenestrates together with brachiopods, stromatopoids, and corals indicate a high-energy reef environment on the Koněprusy submarine elevation in the upper Eifelian. Morphology of fenestrates and high morphological disparity of brachiopods are remarkably similar to the faunas of the Pragian age in the Koněprusy area suggesting a similar reef environment. The upper Eifelian age of the locality is evidenced by conodonts of the Tortodus kockelianus Zone.

Index of Fossiliferous Localities of the Mílina Formation (Lower Ordovician of the Prague Basin, Czech Republic)

Pubblicato online: 30 Dec 2016
Pagine: 17 - 50

Astratto

Abstract

Twenty-two fossiliferous localities of the Mílina Formation described herein represent all fossil sites of this unit we have found mentioned in publications. Fossil taxa from relevant papers are summarized and historic names used for the localities are listed. Updated lists of fauna are compiled for each locality; based on these an overall list for the formation is concluded.
