Nope. Nopcsa explicitely starts with a bipedal Proavis, and AFAIK with a

Sounds interesting.

BTW, going to any of Vienna's university libraries -- for example -- does
hardly give one the exercise of walking, unless you are content with 5
minutes, and I wouldn't call the usual street air outside of the subway and
bus/tramway "fresh air", neither the one in the libraries themselves. :-|
