Figure 4 in Osteological comparison of casque ontogeny in palaeognathous and neognathous birds: insights for selecting modern analogues in the study of cranial ornaments from extinct archosaurs

Figure 4. Three-dimensional renderings from micro-computed tomography data of a developmental series of Numida meleagris: A, TLG NM006; B, TLG NM002; C, TLG NM004; D, TLG NM003; E, TLG NM007 (see Table 1). Skulls are shown in (top) less lateral and (boưom) dorsal views. Casque elements specific to N. meleagris are indicated by coloured cells [dark red (X) = element not participating at specified age; dark green (✓) = element participating at specified age] in the table, and grey cells indicate bones that do not contribute to bones in the species represented in this figure, but do contribute to others in the study. Dashed line divides specimens without (less) and with (right) casques developmentally present.
