178                  The Origin of Birds and Flight

                     Archaeopteryx was not the only fossil bird to have had grasping teeth.
                     Some fossil birds had teeth, some didn’t. But how can teeth prove a
                     relationship to reptiles, when many reptiles don’t have teeth?
                     Crocodiles are really the only group of reptiles that consistently have
                     very well-developed teeth. And of course, even some mammals have
                     teeth and some don’t. 133
                     One very important fact, often ignored, is that the dental structure
                of Archaeopteryx and other toothed birds is very different from that of
                dinosaurs.  According to measurements carried by such well-known
                ornithologists as L. D. Martin, J. D. Stewart and K. N. Whetstone, the
                teeth in  Archaeopteryx and other toothed birds have flat surfaces and
                have broad roots. Yet the tooth surfaces of theropod dinosaurs, alleged to
                be the ancestors of these birds, are serrated like saws, and their roots are
                narrow. 134 Studies by such anatomists as S. Tarsitano, M. K. Hecht and A.
                D. Walker have revealed that some of the similarities suggested between
                Archaeopteryx and dinosaurs are entirely due to misinterpretation.  135
                     All this goes to show that Archaeopteryx was not an intermediate
                form, but merely belongs to a separate classification of toothed birds.
                Seeking to establish a relationship between this creature and theropod
                dinosaurs is highly unscientific.


                     Archaeopteryx’s jawbone
                     It has been claimed that Archaeopteryx’s jawbone resembles that of
                dinosaurs, but during examinations by Haubitz and his team, using
                computer tomography, revealed that its jawbone is in fact identical to
                those of modern birds. 136 The movement of the jaw is another important
                piece of evidence that undermines evolutionist claims. In most verte-
                brates, including reptiles, only the lower jaw is mobile, while in birds,
                including Archaeopteryx, the upper jaw also moves.


                     Archaeopteryx’s finger structure and wings
                     Another blow to the evolutionist thesis comes from Archaeopteryx’s
                finger structure. Development of the forearm bones during the embry-
