Amanitichnus omittus ichnogen. et ichnosp. nov. from the Middle Cambrian,Barrandian area,Czech Republic

The newly established ichnofossil Amanitichnus Omittus ichnogen. et ichnosp. nov. represents a complex burrow system consisting of upward convex conical structures with radiate sculpture, recurring in different stratification levels and connected by a subvertical shaft. The system is interpreted as an intrastratal fodinichnion with some resemblance to epistratal Oldhamia and Glockerichnus. The ichnofossil occurs in the silty Skryje Shale of Middle Cambrian age and is accompanied by common benthic body fossils and by ichnofossils of the Cruziana ichnofacies.
