Abstract

This study is concerned with new excavation methods and techniques for fossil tracks/trackways and its application. Unlike the body fossils such as dinosaur skeletons and isolated bones, the Mesozoic vertebrate tracks and trackways including dinosaurs, pterosaurs, and birds are usually discovered in long-distance trackways. The trackways are also found in a large area of the bedding plane and preserved as two-dimensional and flat characteristic. New excavation methods for fossil footprints reflecting these characteristics have been designed to excavate fossil footprints preserved on wide bedding plane and applied to five excavation fossil tracksites. As a result of its application, the tracks and trackways of dinosaur, pterosaur, and bird were successfully excavated. And based on various excavation cases, the step-by-step process and details of the fossil footprints excavation was proposed.

본 연구는 발자국 및 보행렬 화석의 발굴 방법과 이의 적용에 관한 것이다. 공룡, 익룡 및 새 발자국과 같은 척추동물의 발자국과 보행렬 화석들은 공룡 등과 같은 실체 화석들과는 달리 일반적으로 특정 방향을 향하여 길게 진행한 흔적을 남기거나 넓은 층리면에서 발견되며, 평면적인(2차원적인) 특성을 가진다. 이와 같은 발자국 화석의 특성을 반영하여 비교적 넓은 층리면에 보존된 발자국 화석을 발굴하기 위해 새로운 방법을 고안하였고, 이 방법을 5곳의 발자국 화석 발굴 현장에 적용하였다. 그 결과, 발자국 화석산지에서 공룡, 익룡, 새 발자국과 보행렬 화석들을 성공적으로 발굴하였다. 그리고 다양한 발굴 사례에 근거하여, 발자국 화석 발굴의 단계별 과정과 세부 사항을 제안하였다.
