Palaeoenvironmental implications of Asteriacites lumbricalis in the Coste dell'Anglone dinosaur ichnosite (NE Italy)

The finding of Asteriacites lumbricalis in the Lower Jurassic of the Trento carbon- ate Platform is here integrated with the sedimentological, stratigraphical, and palaeon- tological data for the Coste dell'Anglone ichnosite in order to better reconstruct its palaeoenvironmental setting. The presence of these traces produced by small ophi- uroids support the interpretation, for this geographical sector during the middle-late Sinemurian, of a marginal-marine tidal flat environment. A marginal marine environ- ment is consistent also with the documented existence of sedentary populations of dinosaurs recorded as footprints in the deposits that overlie those preserving Asteria- cites.
