(d) Longitudinal section cut parallel to bedding surface along white rectangle labeled “d” in (a), showing annulae in cross section (arrows). (g) Transverse section cut perpendicular to bedding surface along line labeled “g” in (e), showing a burrow (arrow) underlying Wutubus annularis tube. (h, apex to the left) Longitude section cut perpendicular to bedding surface along line labeled “h” in (e, apex to the right). Note abundant burrows in (e–f).
