Abstract

Seven specimens of raindrop imprints are discovered from the Late Triassic Amisan Formation of Nampo Group distributed in the Myeongam area of Boryeong-City, Chungcheongnam-do. The raindrop imprints are interpreted to had been formed in lacustrine environments under subtropical humid climate during the lowered period of the surface of the water by temporally or seasonally arid climate. The raindrop imprints are the first finding in the Lower MesozoicNampo Group, Korea.

충남 보령시 명암 지역에 분포하는 트라이아스기 후기의 아미산층으로부터 7개의 빗방울자국 표본이 발견되었다. 빗방울자국은 습윤한 아열대의 호성환경하에서 일시적 또는 계절적으로 건조한 기후에 수면의 저하시기에 형성된것으로 해석된다. 이들 빗방울자국은 하부 중생대 남포층군에서는 처음으로 발견된 것이다.
