David Martill, a pterosaur specialist at the University of Portsmouth, UK, says that although the tracks record a «small moment, perhaps no more than three seconds, in the life of a pterosaur», they offer a real insight into the
lives of the ancient animals.
In addition to finding the human footprints, the researchers also found
tracks of ancient animals, from birds to lions, that provide a «snapshot in time of what animals were on the landscape,» says paleoanthropologist and co-author John Harris of Rutgers University, New Brunswick.
As well as helping to explain how bioluminescence evolved, their finding tells a story of the
journey of ancient animals deeper into the oceans.

Located at the bottom of a 137 - foot - deep chimney inside a cave, the pit is littered with
remains of ancient animals and also includes about 28 hominid skeletons dating back to the Middle Pleistocene.
Caitlin Colleary, a doctoral student of geosciences in the College of Science at Virginia Tech, says the original color
patterns of ancient animals can be determined through fossils.
