 What follows is something posted a while back by James Lippard, in
response to a similarly-themed posting by Bob Bales...

You cite Chris McGowan's _In the Beginning..._ below.  If you have this
source, and aren't just citing it via another source, you should
examine the tables on pp. 116-117.  I will reproduce them here:

		Reptilian Condition		Avian Condition
HIP		1. Pubic peduncle present.	No pubic peduncle.
TAIL		2. Long, bony tail.		Short, bony tail.
		3. No pygostyle.		Pygostyle present.

CHEST		5. No bony sternum.		Bony sternum present.
		6. No wishbone.			Wishbone present.
HAND		7. Usually three well-		Only one well-

		9. Metacarpal bones unfused.	Metacarpal bones fused.

ABDOMEN		12. Abdominal ribs present.	No abdominal ribs.

Checklist of Reptilian and Avian Features of Archaeopteryx

		Reptilian Condition		Avian Condition
HIP		1. Pubic peduncle present.
TAIL		2. Long, bony tail.
		3. No pygostyle.
VERTEBRAE	4. Articular surfaces do not
		appear to be saddle-shaped (caution
		is required here because only two
		articular surfaces can be seen).
CHEST		5. No bony sternum.
		6.				Wishbone present.
HAND		7. Three well-developed fingers
		(each with the same number of bones
		as in most dinosaurs).
		8. Three well-developed metacarpal
		bones.
		9. Metacarpal bones unfused.
ANKLE REGION	10. Metatarsal bones separate.
		11. No hypotarsus.
ABDOMEN		12. Abdominal ribs present.
FEATHERS	13.				Feathers present.

Given the above, given that the most recent Archaeopteryx specimen
found had previously been misclassified as the dinosaur Compsognathus,
and given that Hoyle and Wickramasinghe have been arguing that 
Archaeopteryx is a hoax created by carving on a dinosaur fossil, do
you really want to maintain that Archaeopteryx is "100% bird"?

 I think this helps to establish that _A_ really should be regarded as
a transitional form...
 Also, to address another point that you raised that I deleted to save
space, there is a big 'Transitional Fossils Faq' which shows that
transistional fossils are not quite the rarity implied by some anti-
evolution texts.
