New dinosaur footprints were recently discovered in southern Latium (Italy).The tracks all appear slightly differently preserved and are characterized by elongated metatarsal impressions, recording the complex locomotor behaviour of a medium-sized theropod.The spatial distribution and the features of the footprints indicate that the trackmaker adopted a "crouched" position as part of an activity as well as a resting phase suggested by sub-parallel, calcigrade tracks.These new data once again highlight the great potential of ichnological evidence in the study of the biology and behaviour of extinct tetrapods.
