“…The abovementioned sarcopterygian scales stored in Museum Victoria are marked with fine radiating ridges on the exposed external surface, similar to those preserved in some rhizodontids (e.g. Holland et al 2007: fig. 4) and non-madageriids tristichopterids (e.g.…”

“…In overall proportions, NMV P229477 is slightly larger than the vomerine fang of Barameda decipiens from the Carboniferous of Mansfield, Victoria (Holland et al, 2007), a taxon probably 3-4 m in total body length (pers. obs., 2010).…”

“…This morphology is present in rhizodontids, Megalichthys, Eusthenopteron and Tristichopterus (Schultze, 1970). However, the lingual surface of NMV P229479 differs from that of rhizodontids, such as Barameda (Holland et al, 2007) in lacking fine, raised striae on the enamel.

Holland, T. 2010. Upper Devonian osteichthyan remains from the Genoa River, Victoria, Australia. Memoirs of Museum Victoria 67: 35-44.The Genoa River Trackway site in the Upper Devonian Combyingbar Formation represents one of the earliest records of tetrapods (land vertebrates) from Australia. However, the osteichthyan assemblage from the site is poorly known compared to other Devonian tetrapod localities. New information from a tetrapodomorph fish lower jaw possibly indicates the first record of a tristichopterid from the Genoa River Beds. The specimen shares a posteroventral embayment in the profile of lower jaw with Eusthenopteron foordi, Platycephalichthys bischoffi, and Moroccan tristichopterid material, as well an isolated specimen of the 'osteolepidid' Gyroptychius. Polyplocodont and dendrodont teeth are also described from the Genoa River, with the latter indicating the presence of a large, porolepiform taxon. The antiarch placoderm Remigolepis represents the most abundant fossil fish taxon recorded from the Genoa River. The possible presence of phyllolepid placoderm material may support previous suggestions of a pre-Famennian age for the Genoa River Beds.

“…Specimens of Gooloogongia and Barameda have been described in detail by previous authors (Long 1989;, 2001Long & Ahlberg 1999). Recently Holland et al (2007) published a description of a new specimen of Barameda (NMV P212715) along with a reassessment of the Downloaded by ["Queen's University Libraries, Kingston"] at 04:52 20 September 2013 taxonomy of that genus. The authors noted that Barameda material is found in two distinct size-ranges which also show some differences in morphology of the jaw and pectoral fin (see also Jeffery 2003, p. 267).…”

“…A wider interest in rhizodontids as a whole was revived in the 1980s by the discovery of the first specimen to show the overall shape of the body (of Strepsodus; Andrews 1985) and the first detailed description of an articulated skull (of Barameda; Long 1989). Over the last 10 years, interest has centred around the discovery of new rhizodontid material in North America (Sauripterus and Letognathus; Daeschler & Shubin 1998;Davis et al 2001Davis et al , 2004Brazeau 2005) and Australia (Gooloogongia and Strepsodus; , 2001Johanson et al 2000;Garvey et al 2005;Parker et al 2005;Holland et al 2007), and from several phylogenetic studies which suggest that they are the sister group to all other members of the tetrapod total group (sensu Patterson 1993) with the exception of Kenichthys (e.g. Cloutier & Ahlberg 1996;Zhu & Schultze 1997;, 2001Jeffery 1999;Zhu & Ahlberg 2004;Long et al 2006).…”

Cranial morphology of the Carboniferous rhizodontidScrebinodus ornatus(Osteichthyes: Sarcopterygii)

Well-preserved material is described of several specimens of Screbinodus ornatus, a small (approximately 1.5 metres long) rhizodontid sarcopterygian, from the Visean (Mississippian, Carboniferous) of Scotland. This species shows numerous 'typical' rhizodontid characteristics, such as post-parietals with a median 'tail', pectoral lepidotrichia with elongated basal segments, large symphysial tusks on the dentary and a 'reverse' overlap relationship between the cleithrum and clavicle. It also shows several characters unknown in other rhizodontids, such as the loss of the extratemporal and subopercular, and the probable exclusion of the postorbital from the orbital margin. A phylogenetic analysis finds that rhizodontids are the sister group to all other members of the tetrapod total group (with the exception of Kenichthys). This confirms that resemblances between derived rhizodontids and digited stem-tetrapods such as Acanthostega (noted by several previous authors) are due to convergence. A second analysis finds that Screbinodus is a derived rhizodontid, and part of a monophyletic Carboniferous radiation.

The hyomandibulae of rhizodontids (Sarcopterygii, stem‐tetrapoda)

Despite its important role in the study of the evolution of tetrapods, the hyomandibular bone (the homologue of the stapes in crown-group tetrapods) is known for only a few of the fish-like members of the tetrapod stem-group. The best-known example, that of the tristichopterid Eusthenopteron, has been used as an exemplar of fish-like stem-tetrapod hyomandibula morphology, but in truth the conditions at the base of the tetrapod radiation remain obscure. We report, here, four hyomandibulae, from three separate localities, which are referable to the Rhizodontida, the most basal clade of stem-tetrapods. These specimens share a number of characteristics, and are appreciably different from the small number of hyomandibulae reported for other fish-like stem-tetrapods. While it is unclear if these characteristics represent synapomorphies or symplesiomorphies, they highlight the morphological diversity of hyomandibulae within the early evolution of the tetrapod total-group. Well-preserved muscle scarring on some of these hyomandibulae permit more robust inferences of hyoid arch musculature in stem-tetrapods.
