Reflected light photomicrographs of specimens of Dapsilodus obliquicostatus sampled in this study including all element types (Sa, Sb-c, and M elements). All scale bars are 100 ÎĽm and all images are scaled to the same size. These are the same specimens previously characterized by micro-X-ray diffraction (ÎĽXRD)21.
