Why are avisaurids more predatory than other enantiornithines again? Of
course, Boluochia seems predatory judging by its raptoral beak.

Apatornis seems to be a non-neornithine carinate more derived than
Ichthyornis (Clarke, 2002). It consists of a posterior sacrum, the rest of
the referred material made the type of a new taxon by Clarke. The latter
taxon isn't neornithine either, but is also more derived than Ichthyornis.
The earliest neornithine seems to be Gallornis (Neocomian), then a Bissekty
tibiotarsus (Coniacian; Nessov, 1992). Besides these records, there are
many Campanian taxa.
