描述了河北省赤城县寺梁山土城子(后城)组一例极可能的兽脚类恐龙蹲伏迹及相关的足迹,该蹲伏迹也是该组地层目前发现的最大的兽脚类足迹.虽然缺乏前足迹和尾迹,但因保存了左跖骨印、关联的坐骨及可能的耻骨胼胝印被定为蹲伏迹.该蹲伏迹是世界上第三例非对称的兽脚类恐龙蹲伏迹.%A probable theropod dinosaur crouching trace and associated tracks from the Tuchengzi (Houcheng) Formation of Siliang Mountain,Chicheng County,Hebei Province,China are the largest theropod tracks currently known from the formation.Although the crouching trace lacks manus and tail marks,the traces are interpreted as made by a crouching theropod because they include a left metatarsal impression and associated ischial,and possibly pubic,callosity traces.This represents the third known example of an asymmetric crouching position adopted by a theropod.
