Abstract

Excavation of a trench in the floor of a cave at Springbrook, Jackson County, Iowa, yielded bones of nine species of mammals. At a depth of 19 to 24 inches the jawbone of a porcupine and the upper right canine tooth of a black bear were found. There are no museum records of either species in Iowa. Intermingled with these remains were clam shells and ashes probably left by cave dwelling Indians. Historical literature indicates that the bear probably was extinct in Iowa before the Civil War and the porcupine before the advent of white settlers.
