记述了辽宁朝阳原家洼九佛堂组发现的原始今鸟类一新属种:朝阳副红山鸟(Parahongshanornischaoyangensis gen.et sp.nov.)。尽管缺失头骨,但其头后特征和红山鸟及一件属于红山鸟科的长腿鸟最为接近,具有该科的一些明显鉴定特征,如前肢相对后肢十分短小,“U”字形的叉骨长明显大于宽等,因此可以归入红山鸟科。新鸟在以下特征上可与红山鸟及长腿鸟相区别,如叉骨支近端侧向压扁,联合处有一条深沟;胸骨末端有两对后凹陷,在龙骨突与侧突之间有短的后突;第Ⅱ指第1指节相对更加短粗,第2指节细长;耻骨具有膨大的耻骨脚等。新材料的发现为红山鸟类提供了新的解剖学特征,还为研究早期今鸟类的多样性提供了新材料。
Described a new species of primitive birds: Chaoyang Mangroves bird (Parahongshanornischaoyangensis gen.et sp.nov.). Although missing the skull, its head posterior features are the closest to the Redshanks and one long-legged bird belonging to the Redshank family, with some obvious identification features of the family, such as the short forelimbs relative to the hind legs, “U” The long wishbone is significantly longer than the width, so it can be classified as red bird. The new bird in the following characteristics can be distinguished from the red bird and long legged bird, such as the lateral crus of the distal end of the wishbone branch, the joint has a deep groove; sternum at the end of two pairs of posterior depression, keel and lateral protrusion There is a short kyphosis; the first refers to the first section of the second finger is more stubby, section 2 slender; pubic symphysis with pubic feet and so on. The discovery of new materials provided new anatomical features for Redshann birds and provided new material for studying the diversity of early birds.
