Glossifungites saxicava Łomnicki, 1886

Emended Diagnosis.—Horizontal to oblique, tongue-shaped burrows with a central area more depressed or narrower than the outside edge. The distal part is usually wider than the aperture, which approaches a fi gure-eight shape. The outer surface is covered by bioglyphs: longitudinal ridges disposed along the outside edge and shorter crisscrossed ridges located in the depressed central area. In both cases, bioglyphs are oriented roughly parallel to the overall tongue-shaped morphology. Burrows are passively filled, i.e., lacking any kind of spreiten (adapted from Łomnicki, 1886).

Some subsequent workers have regarded Glossifungites saxicava to be a junior synonym of Rhizocorallium jenense Zenker, 1836 (see discussions in Uchman et al., 2000; Knaust, 2013).
