  • Episode 246 - Gharials
    Jun 21 2026

    Happy Croc Month!

    Most living crocodilian species look pretty similar overall – that’s why there are so many tips for telling alligators from crocodiles – but one group really stands out with their bulging eyes and remarkably slender snouts. This episode, we explore the various features and habits that make gharials unique among crocs, and which have caused no end of confusion for scientists trying to sort out their evolutionary history. And, of course, we’ll take a trip into the fossil record to visit some of the most extraordinary long-snouted crocs of the distant past.

    In the news: hagfish eyes, dinosaur arms, fungal spores, and fishing dinosaurs.

  • Episode 245 - Cycads
    Jun 7 2026

    Cycads are cousins of conifers, and although they can be found throughout the modern tropics, they are often considered a visual indicator of prehistory. This episode, Aly joins us to explore what sets cycads apart from other plants, what we know of their deep history, and whether they truly deserve their reputation as dinosaur food.

    In the news: toothless crocs, Arctic mammals, turtle relations, and crater life.

Currently my favourite podcast. As a fan of all 'ologies' that study the creation and evolution of earth and it's life, I really enjoy listening to this podcast. David and Will clearly love and are very enthusiastic about their subject. This makes the subject matter interesting and fun to listen to. I even like the bad Dad jokes! 😃

interesting, informative and entertaining.
