Species abundance: H = highly abundant: 101-1000 specimens per field of view; V = very abundant: 11-100 specimens per field of view; A = abundant: 1-10 specimens per field of view; C = common: 1 specimen per 2 to 10 fields of view; F = few: 1 specimen per 11 to 100 fields of view; R = rare: 1 specimen per 101 to 1000 fields of view; S = sparse (? not defined by author), - = absent. Small case letters = reworked.物种丰度（Species abundance）分级规则如下： H = 高度丰富（highly abundant）：每个视野（field of view）内可见101~1000个标本； V = 极丰富（very abundant）：每个视野内可见11~100个标本； A = 丰富（abundant）：每个视野内可见1~10个标本； C = 常见（common）：每2~10个视野出现1个标本； F = 稀少（few）：每11~100个视野出现1个标本； R = 罕见（rare）：每101~1000个视野出现1个标本； S = 稀疏（sparse，作者未明确界定）； - = 缺失（absent）。 小写字母代表经再沉积改造（reworked）。
