Comparison of ectomesenchyme-mesoderm distribution in the cranium between the crown gnathostome (chicken; based on the description by Couly et al., 1993) and the lamprey larva. Modified from reference [24]. Crest-derived cells are shown in red, mesodermal cells in blue. Notochord is represented by thick black lines. Note that the chordal cranium is coextensive with the notochord. In the chicken, the prechordal cranium is represented by the interorbital septum, whereas in the lamprey, the ectomesenchymal cranium is exclusively oro-pharyngeal, and the neurocranium is made of mesoderm. Ios, interorbita septum; nas, nasal capsule; nc, neurocranium; ot, otic capsule
