Abstract: New occurrences of Sinusichnus sinuosus Gibert 1996 described in the Cenozoic of Spain, evidence the almost continuous fossil record of this ichnospecies from the Upper Cretaceous to the Lower Pliocene. Morphological and size features of these highly regular sinusoidal burrows have been analyzed, showing a very recurrent constructional pattern through time. Such features are also constant along the ontogeny of the producer. The large number of similarities that this ichnogenus shares with fodinichnial burrow systems, such as Thalassinoides, Ophiomorpha or Spongeliomorpha, point to a crustacean authorship. Since this sinusoidal architecture is also common among some graphoglyptids, other behavioral strategies are discussed. The ichnogenus Sinusichnus occurs commonly in shallow marine environments, in particular to deltaic depositional settings.
