I don't see why Archie couldn't have tackled prey of this size.
_Archaeopteryx_'s feet and jaws (and perhaps its hands as well, though it
risked sullying the wing feathers) would have been quite effective at
ripping the lizard/sphenodont into smaller pieces.
Perhaps _Archaeopteryx_ did include fish

Otherwise it would have had to compete with *Compsognathus*...
I'm sure there was enough small-sized prey to go around on that little
island they shared. And Archie could always fly to another island if food
started to get scarce.
Dan Bensen is probably correct; _Archaeopteryx_ wasn't too fussy in its
choice of prey.
_Allosaurus_, _Torvosaurus_, _Ceratosaurus_, _Stokesosaurus_ and
_Marshosaurus_ all apparently coexisted in the same habitat, and all
probably fed largely (if not exclusively) on terrestrial prey. (Were there
any fish-eating theropods in the Jurassic?)

Sure! I can't explain the evolution of the wingstroke otherwise! :-)
Generation of thrust, in a terrestrial cursor (a la Burgers and Chiappe,
1999) or in an arboreal parachuter or glider. Either way, the wingstroke
was co-opted from the predatory stroke.
