Chemical element distributions within conodont elements and their functional implications Erik Cowing Katvala and Charles M. Henderson Supplementary Data (Figures and Tables) ReadMe File -------------------------------------------------------------------------------------------------------------------------------- All of these data were collected by Erik Katvala and all questions regarding the paper, data, and supplementary figures should be directed to Erik Katvala. All Supplementary Figures and Tables described below accompany the paper Chemical element distributions within conodont elements and their functional implications by Erik Cowing Katvala and Charles M. Henderson. Supplementary Figure 1 references Figure 2 within the paper in Paleobiology. Supplementary Figure 2 provides supplementary plots to Figure 2 in the paper in Paleobiology; data for Supplementary Figure 2 is in Supplementary Table 1. -------------------------------------------------------------------------------------------------------------------------------- Supplementary Figure 1.tif Backscatter electron images of transverse sections of Mesogondolella idahoensis lamberti elements with well-preserved basal body. White dots on image are sample damage done by electron beam after measurement on electron microprobe. Lamellae are visible as layers within the crown. Data for (A) is in Supplementary Table 3, and data for (B) is in Supplementary Table 4. Neither conodont is as densely sampled as the one in Figure 2, however the same pattern of light and dark backscatter brightness is visible in the images, and the same chemical trends are readily visible in the data. Supplementary Figure 2.tif Contoured maps of chemical element concentration on a conodont element of Mesogondolella idahoensis lamberti. Units of concentration are the number of ions in the chemical formula. -------------------------------------------------------------------------------------------------------------------------------- The four Supplementary Tables are stored in both Excel (.xls) and comma delineated text (.txt) formats.
