Another alleged reptilian feature of Archaeopteryx was its possession of teeth. If this is a feature derived from a reptilian ancestor, and toothed birds subsequently evolved into toothless birds, then the fossil record should produce intermediates documenting the gradual loss of teeth in birds.nother alleged reptilian feature of Archaeopteryx was its possession of teeth.
