Cruziana

Cruziana is one of the most recognizable trace fossils ascribed to arthropods. It ranges throughout the Phanerozoic and encompasses a diverse set of morphologies. The distinct features of Cruziana have incited fierce debate regarding its mode of formation. Here, we discuss critical aspects of trace fossil formation, namely epibenthic versus endobenthic origin and the ethology of the producer.
