“…In fact, as shown in Table 2, the vast majority of the individual pectoral muscles found in urodeles are present in lizards (e.g., at least 26 of the 29 Ambystoma pectoral muscles listed in that table are seemingly present in Timon). It should be noted that apart from the muscles listed in that table, other pectoral muscles may be eventually found in extant tetrapods: for instance, Shellswell and Wolpert (1977) have mentioned that some birds may have about 50 distinct muscles in the wing, a number that is significantly greater than the number of pectoral muscles found in tetrapods such as urodeles and lizards (see Table 2; see also Romer, 1922Romer, , 1924Romer, , 1944Howell, 1933aHowell, ,b, 1935Howell, , 1936aSullivan, 1962;George and Berger, 1966;Jarvik, 1980;Pough et al, 1996;Kardong and Zalisko, 1998;Gibbs et al, 2000Gibbs et al, , 2002Kardong, 2002;Moro, 2003, 2006;Moro and Abdala, 2004;Kisia and Onyango, 2005;Walthall and Ashley-Ross, 2006). We plan to provide, in a future work, a detailed account on the pectoral musculature of all the major tetrapod subgroups.…”
