Comments
The active definition is a first-order revision of the initial and only definition proposed thus far (Sereno 1998). Sinornis santensis (= Cathayornis yandica) was chosen as the internal specifier, given the three-dimmensional knowledge of its skeletal morphology and its completeness (Sereno et al. 2002).
