Trichophycus venosus Miller, 1879

Flat, longitudinal, straight to slightly curved burrows preserved as endichnia and hypichnia at the interface of fine-grained sandstone and claystone. The horizontal to oblique, flattened, sand-filled, unlined burrows are up to 4 cm long, 0.5–1.0 cm wide with an abrupt and angular termination. Preservation of longitudinal sections is most common and these exhibit a poorly developed spreiten or a stuffed appearance. Complete burrow parts are rarely preserved. However, in some instances poorly developed parallel and transverse striae were observed on the lower surface of the burrows. The burrows occur in groups and cross-cut one another. T. venosus can be confused with Halopoa imbricata but lacks a lining, a vertical component, and is not organized as connected burrow systems.
