Scientists have discovered evidence of a 13-foot long walking crocodile.

Analysis of 120 million-year-old fossils in South Korea have revealed that some species of ancient crocodiles walked on two legs.
University of Queensland palaeontologist Dr. Anthony Romilio explained: ''At one site, the footprints were initially thought to be made by a giant bipedal pterosaur walking on the mudflat, we now understand that these were bipedal crocodile prints.
''The footprints measure around 24 centimetres, suggesting the track-makers had legs about the same height as human adult legs.
''These were long animals that we estimate were over three metres in length. And while footprints were everywhere on the site, there were no handprints.''
