Whoa, sheesh ... Ornithology is a specialty, focus
on birds as a single, whereas paleoornithologists are
more concerned with the general evolution as a whole.
Doesn't mean that "regular" ornithologists haven'
tackled the question. So, okay: Joel Cracraft, Luis
Chiappe, Gareth Dyke, Alfred Romer has looked at it,
Gerhard Heilmann (not an ornithologist, but wrote one
of the most eminent texts on the matter of
*Archaeopteryx*) understood they were reptiles. This
is during the clarification of what Reptilia was
And only recently have turtles been considered
diapsids or even archosaurs (see Tom Holtz's post)
inclusive of intensive anatomical, evolutionary
analyses (see deBraga and Rieppel, 1997; and Lee,
1995, 1997, 1998).

Dinosaurs are horrible, terrible creatures! Even the
fluffy ones, the snuggle-up-at-night-with ones. You think
they're fun and sweet, but watch out for that stray tail
