From: An early Cambrian agglutinated tubular lophophorate with brachiopod characters
Yuganotheca elegans gen. et sp. nov. from the early Cambrian Chengjiang Lagerstätte, Yunnan, China.
Arrows point to the borders between the upper pair of valves (Avs), median collar (Mc), lower conical tube (Pc) and pedicle (Pe); M = mouth; Lo = lophophore; Va = visceral area; Dg = the terminal pedicle bulb with adhered grains; Se = setae; Ten = tentacles. (a), Holotype, ELI BLW-0091, compare to b. (c–d), ELI BLW-0016AB, part and counterpart; note the lophophore imprint in d. (e), compare to d. (f), ELI BLW-0141A, complete individual with well developed pedicle. (g), close-up view of the marginal setae in Fig. S4f. (h–i), enlarged view of the lophophoral tentacles in Fig. S6b and a. The sketch drawings were made and organized together using CorelDraw 9.0 and finally converted to TIF format. Z. Zhang created these images.
