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：标本馆藏编号列表，包含样本、玻片及玻片位置信息，以及细胞计数、细胞尺寸和菌落尺寸的测量数据。产地代码与样本编号同补充表S1。前缀带有"p"的玻片编号代表孢粉制片玻片（palynological stew slides）。玻片位置以英格兰Finder（England Finder）坐标标注。对于经合理鉴定为完整的标本，会给出完整的细胞计数；另有2例标注为"重建（recon.）"，其存在附着结构断裂导致的间隙，或几何形态上存在空位。对于不完整的菌落，会标注其最小细胞数。细胞尺寸以微米为单位，每个菌落至少测量4次，优先选取未变形的细胞，并报告其平均值。菌落尺寸通常以最接近5 μm的数值表示：对于通过质心测量的斜变形盘状标本，取其长轴与短轴的平均值；对于轮廓更接近矩形的菌落，则取其最大尺寸。
