Re: Gargantuavis neck vertebra
Gerald Mayr, who suggested that the original pelves could be
pterosaurian, now agrees they're avian.
After all, just a thousand years ago there were a whole lot of
similar modest sized moa species crawling around New Zealand.
DNA sez there were only nine moa species in total in the Pleisto- and
Holocene, though with enormous sexual size dimorphism for *Dinornis
maximus* (the big North Island species) and *Dinornis robustus* (the big
South Island species).
Who knows how many gargantuavid (not sure if this is the family name,
too lazy to check) species and genera were wandering around on the
island/s (not sure how many there were, too lazy to check) of
Campanian/Maastrichtian southern France. Must have been a number of
them if that Darwin was right about evolution of the species.
Under which species concept(s)?
Of course, Buffetaut & Angst didn't specify one either.
Chucking isolated material into a species is more often than not a
very bad habit that we need to stifle yourselves on. Like tossing all
Triceratops random bones into T. horridus when it now looks like
there are two or more species separated stratigraphically.
Separated? My impression was they're continuous (according to Scannella
and Fowler), with gradual anagenetic change, so that the questions
become where _and if_ you want to draw lines -- in other words, which
species concept to choose.
