Stratigraphy
| Formation: | Wellington | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: The Early/Lower call is based on the use of Rothleigende to descibe the beds from which the same taxa are known in Europe. | |||||
Lithology and environment
| Primary lithology: | planar lamination,gray lithified dolomite |
| Lithology description: The fossiliferous bed is a dolostone, about 10cm thick and grayish orange (10YR 7/4) with lighter colored mottling. The matrix is extremely hard, with very fine algal laminations, and emits a faint bituminous odor when freshly split. Plant remains occur throughout the rock, but are mostly concentrated on a bedding plane in the approximate center of the bed. | |
| Environment: | fluvial-lacustrine indet. |
| Geology comments: As both Kansas and Texas were near the western edge of Pangaea, it is likely that large areas with arid climate existed in this part of the late Paleozoic megacontinent. The dolostone with algal laminations in which Phasmatocycas was found in Kansas was probably formed in a sabkha enivornment (Gillespie and Pfefferkorn 1986). | |
