This has never been really embraced by most people. It is possible
given the discovery of basal birds with such an arrangement, but at
most, if it was present in Archaeopteryx, it was less developed.

Dromaeosaurs, troodontids, "Megaraptor", and Noasaurus are the
sickle-clawed dinosaurs. And there is a Madagascaran sickle-clawed bird
and if I remember correctly, an Argentine sickle-clawed bird.
