Description Yanornis alimentary canal.png |
Interpretative drawing of the alimentary canal of Yanornis superimposed over IVPP V13558. Enlarged red box shows preservation of sand compacted in the intestines. The grit is clearly too caudally located to represent gizzard stones. The oesophagus is drawn in a way to demonstrate its flexibility; it leads to the small proventriculus (pyloric sphincter indicated by dashed circle), followed by the larger ventriculus, and then the intestines and cloaca. Scale bar equals 1 cm. |
