And of those few, I think the earliest definite examples are younger than 100 
Ma.

There are of course some borderline taxa like _Enaliornis_ and _Gansus_ which 
fall in the "large invertebrate - small vertebrate" feeding guild. But avian 
"raptors" (Falconiformes or not - _Enantiornis_ makes for a reasonably 
convincing predator of smaller vertebrates too IIRC) do not appear until the 
Late Cretaceous.
