Figure 7. Examples of porous surface patterns. A, fuzzy fibrous pattern with visible pores (UF 109039, femur). B, fuzzy fibrous pattern without visible pores (UF 109039, humerus). C, etched porosity with connecting surface grooves (UF 38974, femur). D, etched porosity (FWC 35119, humerus). E, porous surface (top) grading into radiating fibrous surface (bottom) (FWC LGS1, femur). F, dotted porosity (FWC LGS2, femur). G, overprinted etched and dotted porosity, etched more prominent (ROM R4415, femur). H, overprinted etched and dotted porosity, dotted more prominent (FWC LGS1, femur). Scale bars = 1 cm.
