Abstract

A large temporary excavation in the Middle Ordovician in the NE part of the Barrandian at Praha-Vokovice (Červený vrch Hill) was studied. Volcanic products forming the lower part of the exposed Ordovician sequence are represented mostly by basalts and basaltic tuffs. The lowermost parts of the Šárka Formation contain very rich graptolite and phyllocarid fauna, whilst benthic organisms are very rare. This faunal association contrasts with the younger 'Euorthisina-Placoparia Community' sensu Havlíček and Vaněk (1990) and enables comparison with other localities in the lower part of the Šárka Formation in the Prague Basin.
