... Formation is of interest because in Keokuk County the Pella immediately overlies a fossil tetrapod deposit that is the oldest of its kind in North America. It sits above Romer’s Gap in the fossil record of early tetrapod evolution. Occurrences of the foraminifer Asteroarchaediscus rugosus indicate...

... on the groundwater-table level). The Burlington-Keokuk is particularly noted for springs ( Vandike, 2001 , p. 53). In the setting around Wilson’s Creek Battlefield, chert beds or thin shale beds likely provided semi-permeable confining layers at the base of an unconfined aquifer. Springs played an important role...
