Up for an adventure holiday? Then join host David Mountain as he travels back to the Permian, perhaps the most infamous interval in all Earth history. From giant insects to sabretooth reptiles to a truly massive mass extinction, the Permian promises to be a trip like no other.

Providing some much-needed travel tips are Dr Neil Brocklehurst, a palaeobiologist at the University of Oxford (https://neilbrocklehurst.weebly.com/; https://twitter.com/palaeo_neil) and Dr Suresh Singh, a palaeontologist at the University of Bristol (https://twitter.com/palaeosingh). If you like what they're talking about then make sure to check out their research!
