Fossils in calcareous shale subunit of Lake Neosho Shale
Olive gray calcareous shale with brownish iron oxide
stains in the
calcareous shale subunit of the Lake Neosho Shale. White spots are
invertebrate fossils, including mainly brachiopods and molluscs.
High-quality fossils are difficult to collect because the shale breaks
irregularly and shell material is soft, possibly due to partial leaching
during modern weathering. Black patches in the piece at the upper left
are carbonaceous material, the presence of which suggests deposition
in a near-shore setting.
