For this episode of The Backpacker's Guide To Prehistory, host David Mountain travels all the way back to the Devonian period, 419-359 million years ago. In this weird world of giant fungi and armour-plated fish, what creatures should you look out for? Where should you pitch your tent? And should you really take a dip in Devonian waters?Providing the answers are two Devonian experts: Dr Sandy Hetherington, a palaeobotanist at the University of Edinburgh (https://www.ed.ac.uk/profile/dr-sandy-hetherington; https://twitter.com/Sandy_Heth), and Dr Alice Clement, a palaeontologist at Flinders University (https://www.flinders.edu.au/people/alice.clement; https://draliceclement.com/; https://twitter.com/DrAliceClement). Massive thanks to Sandy and Alice for sharing their advice. If you're interested in the evolution of forests and tetrapods - and I know you are - then make sure to check out their research!
