Abstract

Road-making activity, the opening of new gravel pits and drainage ditches, and natural erosion have brought to light an unusually large number of fossil bones. A large ditch near Avoca has yielded an excellent skull of the giant beaver, Castoroides ohioensis, and at the same place a humerus of the great ground sloth Megalonyx. From Wayland comes a perfect tibia of the same kind of sloth and near it was found the crown of an unerupted mastodon molar. A well preserved, but worn down, tooth of the Columbian elephant was found in a gravel pit at Hartley and a part of a tusk at Bellevue. The skull of a large elk bearing a fine pair of antlers was taken from near the base of the Des Moines River bank at Irvington. The skull of a small deer from a gravel pit at Eddyville completes the list. Illustrations.
