osteocolla
noun[Gr. a bone, and glue.]
A carbonate of lime, a fossil formed by incrustation on the stem of a plant. It is found in long, thick, and irregular cylindric pieces, generally hollow, sometimes filled with calcarious earth, and in size, from that of a crow’s quill to that of a man’s arm. It is always found in sand. That word takes its name from an opinion that it has the quality of uniting fractured bones.
