根据可能发现于江西赣州晚白垩世南雄组地层中一件标本报道了窃蛋龙科一新属种——斑嵴龙。新标本具有以下不同于其他窃蛋龙属种的特征:由前颌骨和鼻骨形成的脊冠具有阶梯状的后端,表面有两个纵向的沟槽和许多倾斜的条痕;外鼻孔延长,其后侧与眶骨相近;翼骨腭骨支背缘有一深窝;齿骨后背缘有纵向沟槽;上隅骨前背缘有小结节。斑嵴龙腭部和下颌的一些特征不同于窃蛋龙科的其他属种,但近似于更原始的窃蛋龙类。这些特征表明斑嵴龙代表窃蛋龙科中相对原始的一个属种。这一系统发育假说得到了定量的系统发育分析的支持。斑嵴龙的发现不仅增加了晚白垩世窃蛋龙科的分异度,而且为这一类群的特征演化提供了重要信息。
According to a specimen that may have been found in the Late Cretaceous Nanxiong Formation in Ganzhou, Jiangxi, a new genus Spiny Dragon is reported. The new specimen has the following features that are different from the other species of Euphelium: The crest formed by the premaxilla and the nasal bone has a stepped posterior end with two longitudinal grooves and many oblique streaks on the surface; , The back side and the orbital bone is similar; wing margin of the palatal margin of the wing has a deep nest; back edge of the tooth has a longitudinal groove; upper nodule front nodules nodules. Spines ridge Dragon palate and lower jaw some of the characteristics of the other species is different from the other families, but similar to the more primitive spider egg dragon. These features indicate that the cercariae represents a relatively primitive species in the family Elliottidae. This phylogenetic hypothesis is supported by quantitative phylogenetic analysis. The discovery of the spiny crest dragon not only increased the diversity of the late Cretaceous Emeudidae, but also provided important information for the evolution of the characteristics of this group.
