Upper Cambrian trilobite ichnocoenosis from Wielka Wisniowka (Holy Cross Mountains, Poland)

Description is given of the Upper Cambrian trilobite ichnocoenosls, i.e. a trace assemblage of the various life activities of trilobites, from the shallow-water marine deposits at Wielka Wisniowka in the Holy Cross Mountains (Gory Swietokrzyskie). These traces occur either on the upper sides of layers (true traces) or on the lower sides of layers covering grooves made by trilobites on the sea bottom (sole markings = hieroglyphs). Hieroglyphs are the more common forms. Out of them, Rusophycus sp., Cruziana sp., Diplichnites sp. an Dimorphichnus sp. have been de scribed in greater detail. Bergaueria perata Prantl and Diplocraterion sp. hieroglyphs are also encountered in the trilobite ichnocoenosis here reported.
