文中记述的窃蛋龙类一新属新种：遗忘始兴龙Shixinggia oblita gen.et sp.nov.是由北京自然博物馆于1995年采自中国广东省南雄盆地的始兴县。它具有以下特征：相对短的肠骨前突，肠骨高度与长度之比率大，并且肠骨的前突及后突的腹边缘均高于髋臼的背边缘。遗忘始兴龙还显示另一特征为股骨近端转子嵴内表面具有一大的气孔，胫骨近端也有类似的相对小的孔，而这些孔在其他已知的窃蛋龙类中均没有报道。这是继2003年报道的黄氏河源龙之后，中国南方第二个新的窃蛋龙类化石。

Shixinggia oblita gen. et sp. nov. herein described was collected from Shixing County, Nanxiong Basin of Guangdong Province, southern China, by the Beijing Natural History Museum in 1995. It is characterized by a relatively short preacetabular process of the ilium compared with its postacetabular process, and relatively high ratio of the ilium height (above the center of the acetabulum) to its length, the ventral margins of the preacetabular and postacetabular processes are much higher than the dorsal margin of the acetabulum, however. Shixinggia shows a special character of large openings present on the anterior mesial surface of the trochanteric ridge in the femur, and the proximal end of the tibia, those openings are not reported in any known oviraptorosaurs. This is the second new genus of oviraptorosaurs from southern China in addition to Heyuannia huangi , which was reported in 2003.
