资源简介:
Sediment depth is given in mbsf. Abundance estimates as follows: A = abundant (>10 specimens per field of view [FOV]); C = common (1 -10 specimens per FOV); F = few (1 specimen per 2-10 FOV); R = rare (1 specimen per 11-100 FOV). ? = questionable occurrence, - = not found. For zone designations and stages see: Lees (2002, doi:10.1006/cres.2003.1021).
沉积物深度以海底以下米(meters below sea floor, mbsf)为单位。丰度估算分级标准如下:A为丰富(每视野(field of view, FOV)内标本量>10);C为常见(每视野内标本量为1~10);F为稀少(每2~10个视野内可见1个标本);R为稀有(每11~100个视野内可见1个标本)。?代表疑似产出,-代表未发现。有关地层带划分与年代地层阶的界定,请参考Lees(2002,DOI:10.1006/cres.2003.1021)的研究。
