When the observed value is 0, the cell has been left empty to make reading easier.

N = number of individuals considered, per lot; n.c. = data not collected; codes in brackets indicate the anomalies considered (see Table 2).

¹ [83];

² [81] reports that dentary ossifies endochondrally but being the only reference affirming this, this bone has been inserted among the intramembranously ossifying elements.
