Stratigraphy comments: "...clearly younger than the M. belophorus Zone, and probably corresponds in age to the C. perneri-G. nassa-P. frequens Zones of the Upper Wenlock. |
Lithology and environment
Primary lithology: | volcaniclastic,shelly/skeletal "limestone" |
Lithology description: "...tuffaceous limestones containing abundant crinoidal detritus... | |
Environment: | marine indet. |
Geology comments: "...benthic fauna, inhabiting a shallow water environment on top of the volcanoclastic elevation...Judging from the fact that most of the brachiopods are preserved as articulated specimens unworn by transport, with all details of external morphology, we may conclude that the brachiopods inhabited a relatively quiet water environment, possibly protected by tuffaceous sediment bars agains wave action. A shallow, subtidal position is suggested...in the BA 3 position...Locally the abundance of Plicocyrtia mayh indicate presence of a soft bottom." |
Taphonomy
Collection methods and comments
Collection excludes: | some macrofossils |
Reason for describing collection: | paleoecologic analysis |
Collection method comments: Authors give relative abundance data (very rare, more frequent, frequent) for brachiopods. "The list [of brachiopods] in Table 15.5 is incomplete because distributions of some species have not been verified by our field investigations." "It was called the Cyrtia petasus Horizon by Horny (1955, 1962)." Not all trilobites included. Check Horny (1955) for more. |
