Resumen:
Neoichnology is an actualistic view of how organisms are connected with theplace where they live, providing modern models and ideas that serve as analogous.At Chubut province (Patagonia), in the Golfo Nuevo beaches lives a polychaetethat inhabits at the same time in rocky abrasion platforms and sandy intertidalsediments. The traces made by the worm can be compared with Caulostrepsislikein hard substrates while in soft-sediments are comparable with Skolithos-Arenicolites- like structures. The worm builds a chimney over the substrate, thatcan be removed by tidal activity, and incorporated into the surroundings as anichnoclast. The present short note is intended to describe this occurrence anddiscuss its importance to ichnology.
