An anatomical cavity that is part of the olfactory apparatus. This includes the space bounded anteriorly by the nares and posteriorly by the choanae, when these structures are present.
Comment:
[homology-note] "Despite significant modification to the nasal cavity within Archosauria and its extreme hypertrophy and supraorbital development in Lambeosaurinae, the neural olfactory system and the olfactory region of the nasal cavity proper retain their plesiomorphic positions and associations, suggesting that this system is highly conserved in vertebrate evolution.[well established][VHOG]" xsd:string {date_retrieved="2012-09-17", external_class="VHOG:0000271", ontology="VHOG", source="DOI:10.1666/0094-8373(2006)032[0109:NCHACC]2.0.CO;2 Evans DC, Nasal cavity homologies and cranial crest function in lambeosaurine dinosaurs.
