Ceratopsians are some of the most iconic dinosaurs that we recognise today including animals like Triceratops and Styracosaurus, with their big horns and frills. But is that what all 'horned dinosaurs' looked like? In fact, early ceratopsians were small and horn-less, sharing other characteristics with their larger, more derived relatives.

At the The Society of Vertebrate Paleontology 2014 we met up with Dr. Andy Farke from the Raymond M. Alf Museum of Paleontology in California and discussed ceratopsian diversity and a new species he was involved with naming and describing.

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.
