What do scientist think about the archaeopteryx?

The first bird to inhabit the Earth is believed to be the Archaeopteryx (meaning 'ancient wing'). It was a cat-sized bird with several reptilian features. It had a beak containing sharp teeth , claws on its wings, and a long tail with bones in the middle. They had wings, feathers and a furcula. (The furcula or wish bone in birds is a forked bone that joins the right and left shoulder joints.) Not much is known about this bird's direct ancestors or descendeants.
