The answer to how pre-historic animals made it from the water to land has been discovered in the Scottish Borders.
Fossils belonging to a small amphibian with limbs were found on a beach at Burnmouth and now a team of experts are working to fill a gap in knowledge which dates back 15 million years.
Burnmouth is now firmly on the palaeontology map. It was here that a self-taught palaeontologist called Stan Wood identified a piece of rock that contained the vital missing answer.
The discovery has been hailed as monumental for the understanding of how these creatures, known as tetrapods, ended up on land.
The studies of the 360 million year old rocks could go on for a decade, due to the slow nature of the work.
Scientists can now push on and discover the environment these tetrapods lived in.
