The bioerosion of bird bones

This study presents a synthesis of the evidence for modern archaeological, and palaeontological bioerosion of vertebrate tissue. It describes the first evidence for the bioerosion of modern, archaeological and fossil bird bones. A new form of bone bioerosion, known as Hackett tunnels, is defined. The bioerosion of vertebrate tissue by cyanobacteria and algae in modern marine and lacustrine environments is also described. Archaeological evidence indicates that the destruction of bone by bioerosion occurs in other terrestrial environments, such as cave deposits and middens. Bone from marine and lacustrine environments that appears to be macroscopically well preserved can have large amounts of microscopic fabric destruction. © 1997 John Wiley & Sons, Ltd.
