“…(2001) combines tooth plates with a narrow, elongate skull. In spite of this, numerous authors do not consider Orlovichthys to be closely related to Rhinodipterus (Campbell and Barwick 1990; Krupina et al . 2001; Schultze 2001) on the basis of its unusual dagger‐like predatory teeth, radically different from the tooth plates of Rhinodipterus .…”

A new species of long‐snouted lungfish from the Late Devonian of Australia, and its functional and biogeographical implications

A new species of the Late Devonian lungfish Rhinodipterus is described from the Frasnian Gogo Formation, northern Western Australia. The description is based on a single specimen preserved in a small concretion, represented by elements of the skull roof, lower jaw, palate, neurocranium, hyoid arch, pectoral girdle and other parts of the postcranial skeleton. Rhinodipterus kimberleyensis sp. nov. differs from other species in the shape of its parasphenoid, number of tooth rows, nature of the tooth plates and characteristics of the skull roof. Functional morphology suggests Rhinodipterus kimberleyensis sp. nov. had a weak bite and may have fed off the reef substrate. Rhinodipterus kimberleyensis sp. nov. possessed a suite of skeletal characters that suggest it may have breathed air. Morphological comparison and a cladistic analysis place Rhinodipterus crown-ward of all other Gogo lungfishes and closely related to Oervigia, Andreyevichthys and Orlovichthys. Faunal comparisons between Australia and Laurussia indicate palaeobiogeographical links existed between these landmasses during the Middle to Late Devonian.

Analysis of Early Devonian dipnoan tooth-plates has been discussed extensively over the last twenty years. A recent discussion by AHLBERG et al. (2006) used cladistic methods with a range of characters, and reached the conclusion that the dentitions underwent extensive and non-parsimonious evolution in their early history. CAMPBELL & BARWtC~ (2000) had proposed that such morphological designs of dentition formed the basis for phylogenetic development, but the cladistic analysis indicated that this was not so. On the other hand we consider that the basic dentition types developed independently by genomic changes (gene regulation) in the Early Devonian. Further development of these designs took place in the later Devonian and subsequently, by Neo-Darwinian micro-evolutionary processes. As well as the distinguishing development ofpalatal biting, new evidence indicates that the Dipnoi were separated from other sarcopterygians by modification of the gill system and the long transverse anodeithrum that lay across the roof of the gill chamber. Further evolution took place within this framework of the Dipnoi so defined. New discoveries within the Early Devonian group are described. It is possible that some genera that have been difficult to place taxonomically (e.g. Diabolepis), were examples of new designs developed by genetic regulation, and they were short lived in competition from the few successful groups. The new lineages based on dental types continued into the later Devonian carrying a large number of older genetic units. These would have evolved in parallel by Neo-Darwinian principles, producing similarities that would have been recognised by cladists as synapomorphies.

New cranial material of the ‘rhynchodipterid’ lungfishSoederberghia groenlandicafrom Upper Devonian (Famennian) strata in East Greenland is described. Previously unknown structures identified here include components of the hyoid arch (ceratohyal, hypohyal) and the lower jaw (prearticular, dentary). Earlier interpretations of the cheek and mandible ofSoederberghiaare reconsidered in the light of new fossil specimens. Some of the difficulties in assessing the homologies between cheek bones inSoederberghiaand those of other lungfishes stem from confusion over the arrangement inRhynchodipterus, and a revised interpretation of this genus is proposed. The single infraorbital bar found inSoederberghiaprobably originates, in part, from an expanded bone 10 (quadratojugal) of the kind found inGriphognathus. Hypotheses that posit ‘rhynchodipterid’ polyphyly seem unlikely in light of a set of derived cranial characters that define a coherent radiation of long-snouted, denticle-bearing lungfishes known from the Late Devonian. The hypothesis presented here places ‘rhynchodipterids’ as a paraphyletic grade with respect to fleurantiids.Rhynchodipterus,Soederberghia, and fleurantiids form a clade to the exclusion of the species ofGriphognathus.G. minutidensis the sister taxon to this apical group, whileG. sculptaandG. whiteiare more remote from it.
