The concept goes all the way back to the 1858 ichnological research of the Reverend Edward Hitchcock performed on the Newark Basin dinosaur tracks. Because underprints are produced indirectly they can only preserve the basic anatomy of the trackmaker's foot, whereas true tracks can preserve fine details skin impressions in favorable circumstances.〔 ==Other usage of the term== Richard Thulborn has used the term "underprint" to refer to a different phenomenon. Thulborn applied the term to track fossils created by the erosion of track casts where the removal of the cast from the track leaves only the impressions of pads in the underlying rock.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Underprint (ichnology)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
