The fossil record is far from complete. The ancestor of modern birds most
likely occured sometime within the middle Jurassic (the Triassic dinosaur
Protavis is not a bird) and most likely somewhere in Europe (ideal island
habitats). Archaeopteryx is most likely a dead end in the evolution of modern
birds. Early Cretaceous maniraptoran dinosaurs may be the end result of
flightless bird development.
