Footprints of History?


A very impressive array of 130m year-old fossil footprints of enormous dinosaurs have come to prominence on the Kimberley shoreline of Western Australia (https://www.theguardian.com/science/2017/mar/28/worlds-largest-dinosaur-footprints-discovered-in-western-australia). The footprints had long been known to the local Aboriginal tribes but their relevance has only recently been appreciated by scientists (the area was once dismissed by local politicians as being of such little significance, that it was ripe for development). Thousands of footprints from at least 21 different species of dinosaur have been currently identified in what was once apparently a delta merging with the Indian Ocean. The footprints should reveal much about the behaviour of these fascinating reptiles (including which species are found together, whether the animals moved as groups and even stride lengths and probable weights).
