The Glossifungites ichnofacies in the area of its nomenclatural archetype, Lviv, Ukraine

An occurrence of "Glossifungites saxicava”; Lomnicki (=Rhizocorallium jenense Zenker) is redescribed from its type area in Lviv, Ukraine, after more than 100 years since its first report. This trace fossil densely penetrates a Miocene transgressive surface cut in Cretaceous marlstones. Its occurrence is restricted to the top layer of the marlstones, where it was formed in a firmground typical of the Glossifungites ichnofacies. Most probably, the trace fossil was produced during a period of non‐deposition shortly before and at the beginning of deposition of Miocene strata by opportunistic suspension‐feeding organisms, possibly crustaceans.
