Description
Mengciusornis is known from a single specimen, IVPP V26275, a well-preserved skeleton with remains of feathers. Unlike its sister genus Schizooura, which was toothless, Mengciusornis possessed large, curved teeth on its premaxillae, similar to those of the distantly related Longipteryx.[1]
Etymology
The generic name honours the Chinese philosopher Mencius, while the specific epithet is Latin for "toothed".[1]
