Aberratiodontus wui
Taxonomy
Aberratiodontus wui was named by Gong et al. (2004). Its type specimen is LHV0001a,b, a skeleton (A nearly completely articulated skeleton), and it is a compression preserving soft parts. Its type locality is Shangheshou, which is in an Aptian lacustrine sandstone/mudstone in the Jiufotang Formation of China. It is the type species of Aberratiodontus.
It was synonymized subjectively with Yanornis martini by Zhou and Wang (2010).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. Gong et al. 2004 | The holotype is a primitive enantiornithine bird about twice as large as Longipteryx (Zhang et al., 2001). The skull is situated lower and has a well-developed postorbital. The quadrate is like a pillar at the lower region and expanded in the upper region. The furcula differs from that of any other known enantiomithine birds (Sanz et al., 1995; Sanz and Chiappe, 1996), and is similar to that of Confuciusomis (Hou et al., 1999b) or Archaeopteryx (Martin, 1995); but its clavicular branch is longer than those of other known enantiornithine birds. The lateral process of the coracoids is well-developed at the distal end and the scapula is curved externally at the distal end, which differs from that of Confuciusornis and Archaeopteryx. The fact that this bird has the largest number of teeth (up to 21 teeth on the lower jaw of each side) among all of the known early birds is significant. The rows of teeth show characteristics of pseudoheterodont and set it apart from those of the other early birds. The teeth on the rostral side are thin and fine, and the front cheek teeth are very large, like “dentes canini”, and then like Eoenantiornis (Hou et al., 1999a), the middle cheek teeth become smaller, and the biggest teeth are in the back. Additionaly, on the rows of teeth there are some new teeth in different developmental stages. The new teeth grew out of the insides of the rows of teeth, which is similar to what was found in Archaeopteryx (Mixtin, 1991; Howgate, 1984) and crocodilian (Cong et al., 1998). |
