We have talked before about how large some of the giant sauropods were and how being big can really affect your biology, but just how do palaeontologists weight dinosaurs from incomplete skeletons and how accurate will these methods be? Well happily we have a podcast that will tackle those very questions and delve into the history and mystery of working out how heavy dinosaurs were, how we used to get it very wrong and why even now we are not that right. Joining us as a guest this time is F1 podcaster Spanners who, it turns out, is a huge dinosaur enthusiast. He wants to ask a rather different question about dinosaur domestication than you might first expect.
