SMNK PAL 3854 (Early Cretaceous; Elgin and Frey 2012) is an ornithocheirid lacking a skull and vertebrae.

Ferrodraco lentoni (Early Cretaceous; Pentland et al. 2019; AODF 876) is a crested ornithocheirid with oddly gracile wings, possibly flightless. The cervicals were originally reconstructed too small.

Criorhynchus mesembrinus (Owen 1874, = Ornithocheirus clavirostris; = Tropeognathus mesembrinus, Fastnacht 2001) BSp 1987 I 46, Early Cretaceous was a sister to Coloborhynchus and may be congeneric. Both are sisters to Nurhachius.

Distinct from Coloborhynchus, the skull of Criorhynchus was longer, lower and wider. The palatal elements were more robust. The ischium was narrower.
