a MNHN SOT 3657, specimen in oblique lateral view. Five lobopodous trunk limbs are preserved anteriorly, roughly the same length as the diameter of the trunk, and lined with strong dermal papillae. Spine tufts are preserved on raised bases, the degree to which the spines were elevated from the trunk in life is ambiguous. b MNHN SOT 3657, detail of the anterior and trunk lobopods under low-angle lighting. c MHNN SOT 2148a, specimen preserved in dorsoventral view. Head region with expanded lateral regions and a circular sclerite plate, which bears a rim and concentric rings towards its center (which appears to be broken away). A pair of frontal appendages is incompletely preserved at the anterior of the head, evenly annulated, and lined with papillae. d Detail of frontal appendage from MHNN SOT 2148a. tn, trunk nodes. Other abbreviations as in Figs. 1, 3. Scale bars represent 5 mm in a and b, and represent 2 mm in c.
