Episode description

Theropods are what we would classically recognise as the meat-eating dinosaurs of the Mesozoic Era. They are best known from genera such as Tyrannosaurus and Velociraptor but the group is much more diverse and includies herbivores, beaked and ostrich-like forms. It is however the link between theropods and birds that has long-caught the public's attention and perhaps represents one of the most scrutinised evolutionary transitions. As more dinosaurs are discovered with feathers, should we still be asking  where the cut-off point is between the two groups and not if there should be a distinction?

We caught up with Dr. Steve Brusatte, University of Edinburgh,  at the Society of Vertebrate Paleontology meeting, who spoke to us about the relationship between theropods and birds.
