This is almost certainly the result of preservational bias. Most Mesozoic
sedimentary rock was laid down in aquatic deposits. Dry land is ordinarily
where sediment-bearing water flows away from, not to. We'll probably never
find fossils of Mesozoic land birds unless they straggled from time to time
into shoreline areas.
