Most borings consist of branching, anastomosing tubes, approximately 25 µm in diameter, and closed end tubes, 50 to 150 µm long and 20 to 40 µm in diameter. The tube network may close and thereby form major chambers. The small borers were probably most successful in breaking down carbonate particles where rates of bio-genie carbonate sedimentation were low. This content is PDF only.
