The feature influencing most of the head morphology is the retractable parasymphysial tusk whorls, which has caused a reorganisation of the braincase, palate, and lateral displacement of the nasal capsules.

Paleozoic dipnoan phylogeny: functional complexes and evolution without parsimony
This work attempts to reconstruct the relationships between the better known genera using a method that involves the recognition of lineages based on evolving functional complexes, particularly those involved with food reduction and respiration.
Morphology and Phylogenetic Position of the Holodipteran Dipnoans of the Upper Devonian Gogo Formation of Northwestern Australia
It is concluded that holodipterans, Griphognathus (and perhaps other rhynchodIPterids) developed from some unspecified Middle Devonian stock that underwent rapid radiation either at the end of the MiddleDevonian or in the early Late Devonian (Frasnian).

The neurocranium of the primitive dipnoan Dipnorhynchus sussmilchi (Etheridge)
ABSTRACT D. sussmilchi is found to have several distinctive bones forming an otic capsule, a large quadrate and a short parasphenoid; the hyomandibula has a single attachment to the lateral otic; the…
The dipnoan species, Sorbitorhynchus deleaskitus, from the Lower Devonian of Guangxi, China
A dipnoan species from the Emsian of Guangxi, China, Sorbitorhynchus deleaskitus , which has previously been diagnosed in the appendix to a more general paper on dipnoan phylogeny (Cambell & Barwick…
Diabolepis and its relationship to the Dipnoi
This paper criticises many of the observations on morphology discussed by Chang, and contest many ofThe synapomorphies used by workers who do the cladistic analysis.
A new tooth-plated dipnoan from the Upper Devonian Gogo Formation and its relationships
The braincase, mandible and dental structures of the Early Devonian lungfish Dipnorhynchus kurikae from Wee Jasper, New South Wales
Light is thrown on the way tooth plates evolved from a dipnorhynchid pattern through a speonesydrionid pattern to true tooth plates in most later Palaeozoic genera, which are made of dentine.
