Resumo

If we visit dinosaurland we will come across some of the most amazing and puzzling phenomena. For example: how can a flying creature as large as a giant quetzalcoatlus (12-15 m wingspan) actually fly when aerodynamic theory and biology both say that it cannot. Also, how can a giant dinosaur such as an apatosaur pump blood up to its brain (more than 13 m above its heart) when animal energetics and physics say that in no way can it do it. Do we have to change the laws of physics and biology? I don't think so. Instead we have to accept that ancient Earth's atmospheric pressure was very different from what it is today. This talk will explore this new picture of our earth's past. Come explore it with me.
