Craniata (2764 words) |
 | The Craniata, or craniates, include all animals having a skull (or cranium, hence their name), be it cartilaginous or bony. |
| The Craniata are characterized by a skull (initially cartilaginous and fibrous), which includes three types of sensory organs derived in ontogeny from ectodermal placodes; that is, thickened patches of the embryonic skin that sink inward toward the brain where they develop into sensory chambers. |
| Janvier, P. The phylogeny of the Craniata, with particular reference to the significance of fossil 'agnathans'. |
