Discovering missing body parts of ancient fossils: Waves and storms lifted fossils off the seafloor 550 million years ago

Certain specimens of the fossil Dickinsonia are incomplete because ancient currents lifted them from the sea floor, a team of paleontologists has found. Sand then got deposited beneath the lifted portion, the researchers report, strongly suggesting that Dickinsonia was mobile, easily separated from the sea floor and not attached to the substrate on which it lived.
