Afrotheres must have reversed it, as marsupials have the "advanced"
condition (interpreted as an adaptation to galloping). Kangaroos famously
retract theirs before kickboxing. Xenarthra + Pholidota (Edentata) is
polyphyletic according to every single molecular analysis AFAIK.
Re "veloci-vulture": I just wrote I couldn't find the author's name. Sorry,
a name and e-mail address can be found at
http://www.seismosaur.com/Seismo5.html. Most of the rest of the site isn't
as bad as the page on "raptors", but the page on evolution writes IIRC wrong
things about the atheist Darwin. The page on coprolites mentions
"turpines"... that are terpenes, I think.
Now I finally go to bed... :-O
