Abstract
An unusual ichnofossil, herein named Accordiichnus natans, new ichnogenus and new ichnospecies, is described. It is a trackway, middle Early Jurassic in age, found within relatively deep marine sediments of the Apennines (Central Italy). It was ascribed to the combined swimming-bottom-walking action (or half-swimming) of an unknown marine reptile. The inferred mode of life of the trackmaker that is discussed by analogy to moderm forms, can serve as a constrain for estimating the paleobathymetry of the track-bearing pelagic deposits.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
