Stratigraphy
| Stratigraphy comments: Possibly also latest part of Early Ludlow. |
Lithology and environment
| Primary lithology: | black,gray "limestone" |
| Includes fossils? | Y |
| Lithology description: "Forms small banks in dark gray and black, medium bedded, fine-grained limestones." | |
| Environment: | marine indet. |
| Geology comments: "NO evidence of shell transport..This is a soft, level bottom, quiet water, BA 3 community. This community evolved from the slightly older C. aracaensis reef community, subsequent to the cessation of the reef building process in the Ural-Tian Shan region." | |
