Stratigraphy
Formation:Motol
Stratigraphic resolution:group of beds
Stratigraphy comments: PJW: For some reason, this was listed in the Encrinuraspis beaumonti zone: but that is Kopanina and a bit younger. This seems to match the Strophoprion-Eoplectodonta zone, which is Cyrtograptus lundgreni zone, and Homerian.

Secondary lithology:volcaniclastic,gray lime mudstone
Includes fossils?Y
Lithology description: "...brown calcareous shales containing rare concretions of dark micritic to light biodetrital limestones [containing fossils]...Vanek described...blocks of grey tuffitic biodetrital limestone [interpreted as moderately deep, subtidal environment (BA 3)]."
Environment:marine indet.
