辽西喀喇沁左翼蒙古族自治县大城子镇发现了个体巨大的霸王龙类化石,本文对化石点周边进行了实地地质调查和地层剖面测量,通过所测量的剖面与大城子盆地代表性剖面的对比分析,确定了含该霸王龙类化石的层位为下白垩统九佛堂组一段.此外,还对地层沉积与埋藏环境进行了初步分析,认为这一大型霸王龙类接近原地在河流心滩处被埋藏、进而逐渐形成化石.

A large-bodied tyrannosauroid was firstly discovered at Dachengzi Town, Harqin Left Mongol Autonomous County, western Liaoning Province. The geological surveys and section measurements were carried out around and at fossil site. According to the comparison of the measured sections to the typical section in the Dachengzi Basin, it is concluded that the tyrannosauroid-bearing strata are the First Member of the Lower Cretaceous Jiufotang Formation. Moreover, the analyses of sedimentary and taphonomic environments reveal that the large tyrannosauroid was preserved in situ and buried in diara deposits.
