Oviraptor is traditionally depicted with a distinctive crest, similar to that of the cassowary. However, re-examination of several oviraptorids (Clark, Norell & Barsbold, 2001) show that this well-known dinosaur may actually be a species of Citipati, a relative of Oviraptor.
chemoreceptor (kÄÂ´mÅrÄsepÂ´tÉr) , n a specialized sensory end organ adapted for excitation by chemical substances (e.g., olfactory and gustatory receptors) or specialized sense organs of the carotid body that are sensitive to chemical changes in the bloodstream.here are chemoreceptors in the large arteries of the thorax and the neck; called carotid and aortic bodies. These receptors are responsive to changes in the oxygen, carbon dioxide and hydrogen ion concentration in the blood.
