Characteristics of the Bonner Springs Shale
  • Upper Pennsylvanian (Kansas City Group)
  • Variable Thickness
  • Sandy-Silt composition
  • (alternating)
  • Blocky Weathering
  • Fluvial Influence
  • Fossils (Plants)

Park University Bonner Springs Shale
  • Average thickness in Kansas is about 20 feet (6
    m) but ranges from 1- 60 feet (19 m).

Conclusions
  • This locality provides the unique opportunity to
    reconstruct a Pennsylvanian tropical biome in
    terms of the flora and the insect population.
  • The absents of large tree stumps, roots along
    with the alternating layers of sand and silt
    suggests vegetation was being rapidly deposited
    in a floodplain.
  • The matting of the leaves along with horizontal
    and vertical distributions are all consistent
    with the concept that lighter material (leaves)
    were being repeatedly deposited into a
    floodplain.

28
Conclusions continued
  • 4. Due to the higher variability on the Bonner
    Springs in terms of composition and thickness any
    additional information will only help give
    geologists a better understanding of facies
    changes in the Bonner Springs.
  • 5. With additional collecting and research the
    likelihood of finding additional material that is
    remarkable preserved would make the
    classification of the locality as a lagerstätten
    plausible.
