Here is an assortment of vertebrae from several animals: amphibians, bats? and rodents (perhaps some other mammals). This is an excellent lot with 18 pieces. Some of the vertebrae are fused together.This deposit is Pleistocene in age, around 100,000 years old. When the animals died their bones were covered in calcium carbonates along the cave floor. Following information from Wikipedia:The Cumberland Bone Cave is a fossil-filled cave along the western slope of Wills Mountain on the outskirts of Cumberland, Maryland near Corriganville in Allegheny County, Maryland. In 1912 workers excavating a cut for the Western Maryland Railway along Andy's Ridge broke into the partly filled cave. A local naturalist, Raymond Armbruster,observed fossil bones among the rocks that had been blasted loose andwere being removed from the cut. Armbruster notified paleontologists at the Smithsonian Institution, and James W. Gidley began excavating that same year. The cave later became known as the "Cumberland Bone Cave".Between 1912 to 1916, Gidley excavated the Cumberland Bone Cave, where 41 genera of mammals were found, about 16 per cent of which are extinct. Numerous excellent skulls and enough bones to reconstruct skeletons for a number of the species were present. Skeletons of the Pleistocene Cave Bear and an extinct Saber-toothed cat from the Bone
