Abstract

A new trace fossil from the Lower Triassic of northern Italy is described. It is a sinuous resting trace of a bilaterally symmetrical worm-like animal. The anterior end is characterised by a pair of lateral projections. It most closely resembles an acorn-worm (class Enteropneusta) in morphology. As such, it is the only known resting trace of an acorn-worm from the fossil record.
