Last year I was lucky to see Compsognathus and Archaeopterix in Munich. I was
very impressed by their small size. And that's the problem with finding these
middle-late Jurassic theropods, they are so small and delicately built. The
chances of fossilation for these small critters are very very very low.
Chances are improving if you've got a lagerstaetten like e.g. Solnhofen. But
as DinoGeorge noted even there only eight fossils of Archaeopteryx and just
one fossil of Compsognathus have ever been discovered.
And think about it, between the Bathonian and the Tithonian there are very
few small theropods known. That make's quite a gap of about 20ma!
So having found none of these middle-late Jurassic dinobirds doesn't proof
that there weren't any. It just means that we have to wait until more fossils
(hopefully) will be found.
