Abstract
The most abundant fossil in the upper part of the Wapsipinicon beds at Independence and elsewhere in east central Iowa is a fine-ribbed representative of Atrypa reticularis (Linn.). This species is found in every fossiliferous horizon in the Devonian or the state. Indeed, it is worldwide in its distribution and is the "longest lived of all known organisms," ranging from early Silurian through the Devonian into the early Mississippian.
