In this much delayed episode, the value of hybridisation in conservation, the proportions of large pterosaurs, evolving flight from gliding animals, and our choice of the best fossil taxon to find with soft tissue preservation.
The podcast of the famous blog by Darren Naish, with John Conway as the straight-man. Discussion of all things tetrapod and vertebrate palaeontology, and many things not. Warning, this podcast is not peer-reviewed, even if Darren sounds very, very convincing.
