Abstract:
The taxonomy of the predominantly Australian fossil dipnoan genus, Neoceratodus, is revised and the Recent Australian lungfish, Neoceratodus forsteri, and two fossil species, Neoceratodus eyrensis and Neoceratodus nargun, are redefined. Two new species of the related Tertiary genus, Mioceratodus, are described on the basis of tooth plates from central and northern localities in Australia. These are Mioceratodus diaphorus and Mioceratodus poastrus. A new genus, Archaeoceratodus, is erected to include three rare Tertiary species and one Mesozoic species. The Tertiary members of this genus are the type species, Archaeoceratodus djelleh, described originally as Neoceratodus djelleh, and two new species, Archaeoceratodus rowleyi and Archaeoceratodus theganus. The Mesozoic species is Archaeoceratodus avus from Triassic and Cretaceous deposits in southeastern Australia, described originally as Ceratodus avus. All three genera belong in the family Neoceratodontidae.

Abstract:
The transition from water to land by the earliest tetrapods in the Devonian Period is seen as one of the greatest steps in evolution. However, little is understood concerning changes in brain morphology over this transition. Here, we determine the brain–braincase relationship in fishes and basal lissamphibians as a proxy to elucidate the changes that occurred over the fish–tetrapod transition. We investigate six basal extant sarcopterygians spanning coelacanths to salamanders ( Latimeria chalumnae, Neoceratodus, Protopterus aethiopicus, P. dolloi, Cynops, Ambystoma mexicanum ) using micro-CT and MRI and quantify the brain–braincase relationship in these extant taxa. Our results show that regions of lowest brain–endocast disparity are associated with regions of bony reinforcement directly adjacent to masticatory musculature for the mandible except in Neoceratodus and Latimeria . In Latimeria this deviation from the trend can be accounted for by the possession of an intracranial joint and basicranial muscles, whereas in Neoceratodus difference is attributed to dermal bones contributing to the overall neurocranial reinforcement. Besides Neoceratodus and Latimeria, regions of low brain–endocast disparity occur where there is less reinforcement away from high mandibular muscle mass, where the trigeminal nerve complex exits the braincase and where endolymphatic sacs occupy space between the brain and braincase wall. Despite basal tetrapods possessing reduced adductor muscle mass and a different biting mechanism to piscine sarcopterygians, regions of the neurocranium lacking osteological reinforcement in the basal tetrapods Lethiscus and Brachydectes broadly correspond to regions of high brain–endocast disparity seen in extant taxa.

Abstract:
Lepidosirenidae is a clade of freshwater lungfishes that comprise the South American Lepidosiren paradoxa and four African species of the genus Protopterus. These two genera have been geographically separated since the Early Cretaceous break-up of Gondwana, but they share similar biology and skeletal morphology. The lepidosirenid species traditionally were distinguished by a combination of features such as head-to-body ratios, the number of pairs of vertebral ribs, and the presence or absence of external gills, but there are no published discrete skeletal characteristics and no published comparative studies including all extant species. I used High Resolution X-Ray Computed Tomography (CT), X-Ray photography, and alcohol-preserved, cleared-and-stained, and dry skeletal specimens from museum collections to describe the skeletal morphology of all species of lepidosirenid lungfishes in a comparative context. I digitally disarticulated the bones in each CT scan to compile a comprehensive comparative atlas of the cranial and pectoral elements of all extant lungfish. I discovered that the anocleithrum in Lepidosiren paradoxa, which was previously thought to be lacking, is actually present. I also identified skeletal differences between species in the frontoparietal, parasphenoid, supraorbital, and suboperculum. I incorporated those characters into the first morphological phylogenetic analysis to determine the interrelationships of the lepidosirenids. I also used previously published molecular sequence data from the ribosomal RNA gene 16s to run combined morphological and molecular phylogenetic analyses. To generate phylogenetic hypotheses using different types of data and different methods of determining phylogeny, I employed the maximum parsimony, maximum likelihood, and Bayesian inference methods. Lepidosirenidae is monophyletic in almost all analyses, Protopterus is monophyletic in each analysis, and Protopterus annectens and Protopterus aethiopicus are sister taxa in every analysis. The phylogenetic positions of Protopterus dolloi and Protopterus amphibius are incongruent in many of the analyses, which indicates that further examination of the skeletal variation and addition of molecular sequences of different genes is needed. Based on the comparative morphological atlas and the phylogenetic analyses, questions of lepidosirenid biogeography, morphological variation within lungfish, and better identification of lungfish fossils can now be investigated in a more rigorous context.<br>text
