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 anterior pair of valves, median collar, lower conical tube and (in 2a, b, d) pedicle; all scale bars are 5 mm. (a), ELI BLW-0065B. (b), ELI BLW-0101, showing the central lumen (Pc) and the terminal bulb (Dg) of the pedicle. (c–d), showing the oblique growth fila of the lower cone and gut remains. c, ELI BLW-0018A. (d), ELI BLW-0095; note U-shaped lineation interpreted as the digestive tract marked by left (Lg) and right (Rg) parts; note the putative location of mouth (M) and probable anus (?A). (e), ELI BLW-0475A, showing well-preserved ventral mantle canals. (f), ELI BLW-0483B, interior dorsal valve.
