Even though generations of paleontologists have assumed they knew what it
looked like in *Archaeopteryx*. Well, the postorbital is there, the
postorbital process on the jugal is there, but whether they met is unknown.

Really? -- Now don't tell me you've adopted my old argument that a)
*Nomingia* has 24, so *Caudipteryx* may have had 24, too, and b) either the
last preserved vertebra which is shown in Vertebrata PalAsiatica is a
pygostyle (22 + 23 + 24) or a pygostyle (23 + 24) has fallen off... :8-)
