The track level at Parede beach corresponds to an extensive intertidal exposure with moderate dinosaur trampling, considering the dinoturbation index proposed by Lockley and Conrad (1989).
Both microfacies analysis of beds C22/24 and C26 and the palaeoecological requirements of the invertebrate taxa collected from several levels of the section suggest that the dinoturbation occurred in a low-energy tidal flat palaeoenvironment, close to an inner shelf opened to fully marine conditions.
Tracksites with a moderate to high dinoturbation
index (Lockley, 1991) were excluded from the analysis because of difficulties in distinguishing individual trackways; these are considered to be evidence of "group activity" (sensu Ostrom, 1972).
Other authors stated that dinoturbations
are not necessarily evidence of gregariousness but of group activity (Ostrom, 1972).
