Most recent analyses show that Archaeopteryx is somewhat more closely
related to modern birds then either group is to Dromaeosaurids. However,
Archaeopteryx is exceedingly primitive, and the common ancestor of
dromaeosaurids and birds probably looked like something very similar to
Dromaeosaurids, however, are too specialized to be directly ancestral to
