Dr. Farlow and Dinolist members...
Thanks, you jogged a brain cell or two about species. I don't have ANY
training in anatomy or biology and I'm very hazy as to what a 'species'
really is. I had always thought that the definition was a group of
interbreeding individuals. And two different 'species' cannot interbreed
and produce viable offspring. How does this apply to the defining of a
dinosaur species. Obviously we don't have the means to breed dinosaurs, so
we have to rely on anatomy to define the species. How do the two relate?
Do we have a good handle on what anatomical differences are enough to fit
into the definition? Or am I 'full of weeds' with the species definition??

Now that species concepts are being discussed, I have been reading an
interesting treatment of just such matters, albeit for a group other
W.H. Kimbel and L.B. Martin (eds.), 1993, Species, Species Concepts,
and Primate Evolution. Plenum Press.
I found the paper by Niles Eldredge therein (What, if anything, is a
species?") to be particularly informative.
Changing the subject, now comes a query: Does anybody out there off
the top of her/his head know about publications that report values of
the coefficient of variation for postcranial bones--and pedal
phalanges in particular, if such data are available--for species of
dinosaurs, non-dinosaurian archosaurs, birds, crocodilians, or
