The footprints provided information on the soft tissue form and structure that are not usually available in fossilized bones, explained Matthew Bennett of Bournemouth University in Britain, the lead author of the study published in the journal Science.

The upper sediment layer contained three footprint trails: two trails of two prints each, a trail of seven prints and several isolated prints.

The other sediment layer, five meters (16 feet) deeper, preserved a trail of two prints an
