It seems to me Heilmann was right with his hypothesis. Now I am almost 100%
convinced that bird flight evolved from the trees down... At least once.
Heilmann's proposed name "Protoavis" would fit this critter just fine.
I am not one for jumping to conclusions, but it would certainly be
interesting o compare the structures on the forearms of this animal with
the hair on the arms of South American sakis, which (if they do not
actually glide) can make very extensive leaps apparently using the forearm
hair for a bit of extra lift. mind you, I wonder how this can work if the
hairs are not stiffened?
