Abstract

Narrow, moderately curved, irregularly branching surficial grooves, less frequently cylindrical tunnels, occur on tests of irregular echinoid Micraster sp. on the locality Radovesice (Turonian, Bohemian Cretaceosus Basin). These borings are interpreted as post-mortal dwelling or feeding-dwelling borings and compared with the ichnogenus Conchotrema Teichert.
