Chondrogenic differentiation in chameleon carpus. During distal flattening and expansion (a-c), the digital rays are already present and are lightly stained by Alcian Blue. The first elements of the mesopodium to form as cartilage are the Fi, dc4, and metacarpals 3–5. Distal carpal 3 and 5 form next (d, e) with later appearance of the intermedium, metacarpal 2 (f-h) and ultimately the radiale and pisiform (i-j). All embryos were at 107 dpo from clutchmates
