Our understanding of the relationship between birds and dinosaurs has changed a lot over the past fifty years to the point where dinosaurs that are not birds are now referred to as ‘non-avian’. In other words: birds are dinosaurs. Modern birds are not the only type of bird that have ever existed - during the Cretaceous a group known as the Enantiornithines were common. Enantiornithines were feathered animals and, whilst in many ways they looked similar to modern birds, they had teeth and clawed fingers on their wings. A single, small fossil wishbone found in Victoria confirms the presence of these animals in southern Australia during the Cretaceous.
