I'm not saying you're wrong; but I think the answer might be more complicated.
According to one ref (Viohl, 1985), _Archaeopteryx_'s Solnhofen habitat was "a
bushland of conifers and Bennititaleans alternating with areas of sparse
Also, because _Archaeopteryx_ could fly (probably), its ecology presumably
wasn't limited to the immediate vicinity of Solnhofen.

There was some paper by a guy named Klaus Ebel, who argued that bird flight
(and pterosaur flight too) evolved in the water. Then again, he also argues
that all saurischian dinosaurs (non-avian) were aquatic. That tells you where
he's coming from.

I'd expect aquatic 'dino-birds' to have a much better chance of fossilization
than inland, forest-living 'dino-birds'.
