Figure 7 - Lamellar bone histology and endosteal remodeling in other squamate lizards. (A) Cross section of an Iguana iguana femur (AC1896 288). (B) Cross section of a Varanus timorensis femur (MK52920). (C) Cross section of Tupinambis teguixin femur (MK53531). All images were taken under cross polarized light. Note the cross cutting relations in the endosteal bone of V. timorensis and Tupinambis . Also note the more extensive layer of remodeling with secondary osteons in the innermost cortex of Tupinambis . Abbreviations: eb – endosteal bone; pb – periosteal bone; so – secondary osteon. Scale bar in (A) equals 1 mm, in (B) 250 µm, and in (C) 500 µm.
