Got an extra "0" there.

Such as all the other feathered dinos they've discovered lately.

You've been corrected on this point before, IIRC. Archaeopteryx has
nothing whatsoever to do with Hoatzins [other than they are both
"birds"]. Hoatzins are fully modern birds [Neornithes]. They're much
closer to hummingbirds, eagles, penguins and ostriches than to Archy.
Archy, in contrast, is basically just a small theropod dinosaur with
feathers. There are no interesting points of similarity, other than
the presence of juvenile wing claws of hoatzins. In detail a hoatzin
hatchling's clawed wings quite unlike Archy's adult clawed hands.
Humans have fingernails too. Does that make us Hoatzins as well?
[Well, besides the people named "Watson"]

Really? How did you arrive at that number? [or that lack of a
number?] Although doubtless dated,
http://www.handprint.com/LS/ANC/evol.html#chart
seems to indicate about 200-300 specimens [i.e., remains from separate
individuals] of australopithecines and Homo habilis from that time and
earlier. Of course that includes individuals known only from a few
fragments or teeth, but then that fits nicely with the one
Archaeopteryx specimen that is a single feather.
