CONCLUSIONS

The finding of Asteriacites lumbricalis in the Coste dell'Anglone Lower Jurassic site is integrated within the paleoenvironmental contextualization of the area. This ophiuroid trace can be considered indicative of a tidal environment with fully oxygenated and clear waters. Here we suggest that during the upper Sinemurian, this area of the Trento Platform was occupied by marginal-marine, tidalflat embayments with ponds and channels. This interpretation is consistent also with the existence of sedentary populations of dinosaurs recorded as footprints in the deposits that directly overlie those preserving Asteriacites.
