Admin thought this was needing to be moved into it's own topic.
I spose it should go into the Biological Evolution topic under a thread entitled "Archaeopteryx; bird or reptile, or both?"

Are you referring to Archaeopteryx? Hasn't it definitely, especially with recent research, been found to be a bird?
No.
Birds don't have teeth.
Archie's avian features:
Feathers
opposable hallux (big toe)
wishbone
elongated pubis which is directed backward
Archie's reptilian features:
No bill
trunk vertebra are free, not fused
bones are pneumatic
pubic shafts with a plate like transverse cross section
Cerebral hemispheres elongate, slender and cerebellum is situated behind the mid-brain and doesn't overlap it from behind or press down on it.
Neck attaches to skull from the rear as in dinosaurs not from below as in modern birds.
Center of cervical vertebrae have simple concave articular facets.
Long bony tail with many free vertebrae up to tip (no pygostyle).
Premaxilla and maxilla bones bear teeth.
Ribs slender, without joints or uncinate processes and do not articulate with the sternum.
Pelvic girdle and femur joint is archosaurian rather than avian (except for the backward pointing pubis as mentioned above).
The Sacrum (the vertebrae developed for the attachment of pelvic girdle) occupies 6 vertebra.
Metacarpals (hand) free (except 3rd metacarpal), wrist hand joint flexible.
Nasal opening far forward, separated from the eye by a large preorbital fenestra (hole).
Deltoid ridge of the humerus faces anteriorly as do the radial and ulnar condyles.
Claws on 3 unfused digits.
The fibula is equal in length to the tibia in the leg.
Metatarsals (foot bones) free.
Gastralia present.
