Fig. 1 | Overview of Eriptychius americanus PF 1795. a,b, Photographs of part PF 1795a,which had the split face set in epoxy and was manually prepared (a), and its counterpart PF 1795b, which remains in rock matrix (b). Both are shown in an anatomically ventral view.c,d, Digital model of computed tomographic data of the combined part and counterpart with most of dermal skeleton rendered transparent:anatomical ventral view (corresponding to the visible area of the part in epoxy) (c) and anatomical dorsal view (buried in matrix in the counterpart) (d). Colour scheme for renders:blue-greys,cranial cartilages (matching the detailed scheme in Fig.2); transparencies,the dermal skeleton; orange,branchial plates;red, orbital plates.Anterior to top in a–d. ant.tess., anterior tesserae; artic. vent. tess.,articulated ventral tesserae;branch.plate, branchial plate;cran.cart.,cranial cartilages;disp.,displaced;frag.,fragment; L., left;orb.cart.,orbital cartilage;orb. plates,orbital plates; R., right;vasc., vasculature;?, probable.Scale bar applies to all panels.
