Supplementary Table S2 (specimen repository numbers and measurement data) from Colonial green algae in the Cambrian plankton

Supplementary Table S2. A list of specimen repository numbers with sample, slide and slide position information, and measurements of cell count, cell size and colony size. Locality codes and sample numbers as in Supplementary Table S1. Slide numbers prefixed by “p” denote palynological stew slides. Slide position indicated by England Finder coordinates. Complete cell counts are given for specimens reasonably identified as intact, in two cases noted to be a reconstruction (“recon.”) where there is a gap with broken attachment structures and/or an unoccupied position in the geometry. For incomplete colonies the minimum number of cells is noted. Cell size is given in microns from at least four measurements per colony, prioritizing undeformed cells and reporting an average value. Colony size is given usually to the nearest 5 μm based on measurement through the centroid, averaging long and short axes for obliquely deformed discoidal specimens, or representing the maximum dimension for more rectangular-outlined colonies.

补充表S2。本列表收录标本馆藏编号，包含样本、玻片及玻片位置信息，同时提供细胞计数、细胞尺寸与菌落尺寸的测量数据。采样地点代码与样本编号同补充表S1。前缀带"p"的玻片编号代表孢粉学悬浮液制片玻片。玻片位置以England Finder坐标标注。对于可合理判定为完整的标本，将给出完整细胞计数；其中两例标注为"重建（recon.）"，此类标本存在因附着结构断裂形成的空隙，或几何形态中存在未被占据的位置。对于不完整的菌落，将标注其最小细胞数。细胞尺寸以微米为单位，每个菌落至少进行四次测量，优先选取未变形的细胞并报告平均值。菌落尺寸通常以最接近5微米的数值标注，测量基于通过质心的结果：对于斜向变形的盘状标本，取长轴与短轴的平均值；对于轮廓更趋近矩形的菌落，则取其最大维度。
