Dinosaur Osteons This image of a Tyrannosaurus rex foot bone shows bone tissue that has been remodeled by erosion and re-deposition. The variety in color depends on the arrangement of mineral crystals and fibers in the bone. Each small black dot used to house a single bone cell. Some circular and elongated spaces for blood supply are also visible. Credit: Ellen-Thérčse Lamm
