Age range of interval: | 305.90000 - 303.40000 m.y. ago |
Stratigraphy
Geological group: | Lansing | Formation: | Stanton | Member: | Rock Lake Shale |
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: "Rock Lake Member, Stanton Formation, Lansing Group, Missourian Series, Upper Pennsylvanian" (Reisz & Berman, 1996)
all vertebrate remains seem to come exclusively from the basal part of the Rock Lake Shale (see Reisz et al., 1982) |
Lithology and environment
Primary lithology: | brown calcareous,carbonaceous mudstone | ||
Includes fossils? | Y | ||
Lithology description: "dark greyishbrown, moderately well bedded, very carbonaceous, calcareous mudstone" (Reisz et al., 1982) | |||
Environment: | fine channel fill | Tectonic setting: | foreland basin |
Glacial or sequence phase: | transgressive systems tract | ||
Geology comments: "The Rock Lake Shale is a rather thin but otherwise typical ’outside’ shale of a ’Kansas Megacyclothem’ sequence formed as a change from regressive to transgressive conditions occurred [...] The site is located along the western edge of what was, during the Late Pennsylvanian, a shallow, forested stream valley or channel that was eroded into a limestone coastal plain during the latter stages of a major eustatic fall in sea level. As the succeeding rise in sea level occurred, the valley was gradually flooded by estuarine waters" (Reisz et al., 1982).
Sequence stratigraphy is interpreted from the description given by Reisz et al. (1982). The surface of the underlying limestone is the sequence boundary merged with the transgressive surface and the Lake Rock Shale is the basalmost deposit of the transgressive systems tract. |
