Weishampel, D. B. (1981). The nasal cavity of lambeosaurine hadrosaurids (Reptilia: Ornithischia): comparative anatomy and homologies. Journal of Paleontology, 1046-1057.
Notes/Summary (cont): Juveniles of Corythosaurus casuarius and the lambeosaurus do not have lateral diverticula -- so that is developed later (it is smaller in the subadult Corythosaurus that I have worked with in the past). With both these species, as the nasal cavity develops, so does the form (eg. developing the LD - the common median chamber moves back caudodorsally (towards the tail, on top) to sit on top of the cranium (brain case) ).
More terms:
fontanellae - soft spots on an infant's head where the bony plates that make up the skull have not yet come together.
