Figure 3 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 3. Three-dimensional renderings from micro-computed tomography data of immature (A) Numida meleagris (TLG NM002), (B) Macrocephalon maleo (UAZ MM003), and (C) Casuarius casuarius (TLG C004). (Immature specimens are figured to emphasize clearer suture lines.) Broad cranial casque paưerns divided into geminal (sampled neognaths; N. meleagris and Ma. maleo) and disunited (sampled palaeognath; Casuarius casuarius). Skulls are shown in (top) lateral and (boưom) dorsal views with elements that will contribute to the fully matured adult casque false coloured (maroon = nasals; green = median casque element; blue = mesethmoid; orange = lacrimals; purple = frontals; yellow = parietals).
