| 摘 要： | 最近辽西建昌地区报道发现了一系列带羽毛恐龙和翼龙化石, 其赋存化石的地层层位时代一直富有争议。我们结合前人资料对玲珑塔含化石地层剖面进行了野外调查和实测, 厘定了含化石地层沉积层序和时代归属。剖面顶底岩石组合特征主要以溢流相中性熔岩和近火山口相火山碎屑岩为主, 中间层位为河流相-湖泊相碎屑岩。该剖面产有大量叶肢介、介形类、双壳类、昆虫、鱼类、植物化石和大量脊椎动物化石。上述化石指示含恐龙化石地层时代为中侏罗世。通过区域对比认为含恐龙化石地层与区域上髫髻山组地层层序和岩石组合相似, 因此认为含恐龙化石地层为中侏罗世髫髻山组(火山岩同位素年代学年龄范围为152~165 Ma)。

| Abstract: | Although Zheng et al. (2009), and Xu et al. (2009) reported feathered dinosaurs at Linglongta and Yaolugou, Jianchang, Western Liaoning in early 2009, their interpretations of the strata in which the speci-mens were found (as Early Cretaceous by Zheng et al. (2009), and uncertain Jurassic-Cretaceous by Xu et al. (2009)) are questionable. Recently, three new verte-brates (Anchiornis huxleyi (Hu et al., 2009), Darwi nopterus modularis (Lü et al., 2009) and Fen-ghuangopterus lii (Lü et al., 2010)), have been re-ported from Linglongta (Fig.1C). |
