Supplemental data for "Niche expansion of archaeocyaths during their paleogeographic migration: evidence from the Chengjiang Biota"

This is the supplemental data for the article "Niche expansion of archaeocyaths during their paleogeographic migration: evidence from the Chengjiang Biota". It includes five parts:Supplementary Fig. 1 Detailed elemental distribution data of the investigated areas in the main text. A-H, corresponding to the elemental map in Fig. 1L. I-P, corresponding to the elemental map in Fig. 3C. Q-X, corresponding to the elemental map in Fig. 3I. Supplementary Table 1 List of studied fossil specimens. Supplementary Movie 1 3D structure of AC-07-SKb. The goldish-brownish colour corresponds to the skeleton of the fossil, which is preserved with clay minerals. The blue colour corresponds to the iron-rich sediments in the inner cavity. Supplementary Dataset 1 Original data and parameters of the micro-CT scan of AC-07-SKb.  Supplementary Dataset 2 Files involved in the Drishti project processing the original data in Supplementary Dataset 1, including the transfer functions, the segmentation data, and the keyframe used to generate the Supplementary Movie 1.
