Making connections

Palaeontologists today think that Archaeopteryx was not the first bird, although it is a good candidate for the transition between dinosaurs and birds. Like a therapod dinosaur, Archaeopteryx had small teeth and a long bony tail. Like a bird, Archaeopteryx had a wishbone, wings with asymmetrical flight feathers, and broad feathers on its tail. It was the size of raven or smaller.
