用磷灰石和锆石裂变径迹技术研究了山西天镇含恐龙化石地层的年代及地热史。结果表明，恐龙骨骼埋藏年代不会早于晚白垩纪；在７３Ｍａ之前源区曾受到温度达２００─２５０℃的热作用，随后发生冷却、搬运并形成沉积地层。自晚白垩纪恐龙骨骼埋藏至今，该地层一直处于环境温度，没有受到明显的热作用。 Apatite and zircon fission track techniques were used to study the age and geothermal history of dinosaur fossil strata in the Tianzhen, Shanxi Province. The results show that the bones of the dinosaurs will not be buried earlier than the Late Cretaceous. Before the 73 Ma, the source area was subjected to a thermal effect of 200-250 ° C, followed by cooling, handling and the formation of sedimentary strata. Since the Late Cretaceous dinosaur bones have been buried so far, the formation has been at ambient temperature with no apparent thermal effects.
