Eskridge Shale

The Eskridge Shale or Eskridge Formation is an Early Permian geologic formation in Kansas.

Its outcrop runs north–south through Kansas, extending into Oklahoma and Nebraska.

[1] While named a shale, it features extensive, spectacular red and green stacked palosol mudstones, these mudstones showing prominent vertical tubular carbonate concretions, possibly from roots or vertebrate burrows.
