Dorygnathus (the Hauff specimen) Middle Jurassic ~175mya, ~26 cm snout-to-vent length.

Sericipterus wucaiwanensis (Andres et al. 2010; Callovian/Oxfordian, Late Jurassic, 161 mya) IVPP V14725 was considered a sister to Harpactognathus and Angustinaripterus, but the mandible was slender as in SMNS 50164. This is one of the largest dorygnathids and it was very gracile.

Kryptodrakon progenitor (Andres et al. 2014; Callovian/Oxfordian, Late Jurassic, 161 mya) IVPP V18184, was promoted as the basalmost pterodactyloid based on several scraps of small bone (see below). It comes from the same beds as Sericipterus and when placed on a reconstruction, fit perfectly. The two are congeneric or conspecific and not close to pterodactyloids.

Dorygnathus sp (MBR 1920.16) nests with slender Sericipterus in the LPT and these two nest with Fenghuangopterus. Note thevery large anterior teeth.

Fenhuangopterus sp (Lü, Fucha and Chen 2010, Li et al 2014, BMNHC Pooo982, Middle Jurassci, 160mya) nests with the MBR 1920.16 specimen of Dorygnathus, not Scaphognathus, as originally described. Three specimens are known. CYGB-0037 is the holotype.

Fenghuangopterus lii (Lü, Fucha & Chen 2010, CYGB-0037, Middle Jurassic ~160 million years old, ~8 cm skull length, was considered an early scaphognathine. Here it nests with another Fengehuangopterus specimen (above) within the Dorygnathidae.

Fenghuangopterus lii a third specimen ascribed to this genus.
