| 内容記述 | Past degradation of the footprint fossils of dinosaurs in the Oyama district in Toyama Cityis discussed by constructing and comparing the past 3D shapes of the fossils. The 3D shapesof the fossils that appeared in different times in the past were estimated based on the replicasmade by taking a mold in the past and the old photographs taken from various directions indifferent occasions in the past. The change in the degradation rate in the past was argued bycomparing the established 3D shapes in the past. As a result, it was established in the presentstudy that soon after the original outcrop was found by a road construction, a sauropodfootprint located in this outcrop started to degrade, but that the rate is getting smaller as timepasses. On the other hand, the degradation of the ornithopod footprint, newly found on theone-step lower outcrop in an additional excavation, seems to be getting larger. This study, anexamination of the tendency of the degradation fluctuation in the past, will contribute to thediscussion of how to conserve such fossils. | |||||
