陕西商洛地区下白垩统大型兽脚类恐龙足迹
Geological Bulletin of China（2011）
Abstract
记叙了中国陕西省商洛市邵涧村下白垩统东河群2个大型兽脚类恐龙足迹,并将其归于Megalosauripus isp..东河群的时代与热河生物群同期,邵涧Megalosauripus isp.可能可与热河生物群的大型兽脚类恐龙之足部形态做简单对比.此外,邵涧Megalosauripus isp.造迹者的体长约为7.4m,这意味着早白垩世的陕西中南部亦存在着大型的兽脚类恐龙.邵涧Megalosauripus isp.的发现,不仅为中国早白垩世恐龙足迹增加了新的成员,而且为将来在该地区下白垩统中发现大型兽脚类恐龙的骨骼化石提供了确凿的依据.
