Supplementary Material and Methods Specimen collection During 2009-2012 field trips, we collected some new sarcopterygain cranial materials from the type site of Qingmenodus yui (7), including a completely ossified anterior cranial portion (IVPP V16003.5), and a posterior cranial portion (IVPP V16003.6). These two specimens are assigned to Qingmenodus yui based on the shared ornamentation and comparable size with the holotype (IVPP V16003.1). Phylogenetic Analyses a.

  • A New Osteolepidid Fish From
    Rea. West. Aust. MU8. 1985, 12(3): 361-377 ANew Osteolepidid Fish from the Upper Devonian Gogo Formation, Western Australia J.A. Long* Abstract A new osteolepidid crossopterygian, Gogonasus andrewsi gen. et sp. nov., is des­ cribed from a single fronto-ethmoidal shield and associated ethmosphenoid, from the Late Devonian (Frasnian) Gogo Formation, Western Australia. Gogonasus is is distinguished from other osteolepids by the shape and proportions of the fronto­ ethmoidal shield, absence of palatal fenestrae, well developed basipterygoid pro­ cesses and moderately broad parasphenoid. The family Osteolepididae is found to be paraphyletic, with Gogonasus being regarded as a plesiomorphic osteolepidid at a similar level of organisation to Thursius. Introduction Much has been published on the well-preserved Late Devonian fish fauna from the Gogo Formation, Western Australia, although to date all the papers describing fish have been on placoderms (Miles 1971; Miles and Dennis 1979; Dennis and Miles 1979-1983; Young 1984), palaeoniscoids (Gardiner 1973, 1984; Gardiner and Bartram 1977) or dipnoans (Miles 1977; Campbell and Barwick 1982a, 1982b, 1983, 1984a). This paper describes the only osteolepiform from the fauna (Gardiner and Miles 1975), a small snout with associated braincase, ANU 21885, housed in the Geology Department, Australian National University. The specimen, collected by the Australian National University on the 1967 Gogo Expedition, was prepared by Dr S.M. Andrews (Royal Scottish Museum) and later returned to the ANU. Onychodus is the only other crossopterygian in the fauna. In its proportions and palatal structure the new specimen provides some additional new points of the anatomy of osteolepiforms. Few Devonian crossopte­ rygians are known from Australia, and so the specimen is significant in having resemblances to typical Northern Hemisphere species.

  • Constraints on the Timescale of Animal Evolutionary History
    Palaeontologia Electronica palaeo-electronica.org Constraints on the timescale of animal evolutionary history Michael J. Benton, Philip C.J. Donoghue, Robert J. Asher, Matt Friedman, Thomas J. Near, and Jakob Vinther ABSTRACT Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are fundamental to nearly every evolutionary model and process. Rates need dates. There is much debate on the most appropriate and reasonable ways in which to date the tree of life, and recent work has highlighted some confusions and complexities that can be avoided. Whether phylogenetic trees are dated after they have been estab- lished, or as part of the process of tree finding, practitioners need to know which cali- brations to use. We emphasize the importance of identifying crown (not stem) fossils, levels of confidence in their attribution to the crown, current chronostratigraphic preci- sion, the primacy of the host geological formation and asymmetric confidence intervals. Here we present calibrations for 88 key nodes across the phylogeny of animals, rang- ing from the root of Metazoa to the last common ancestor of Homo sapiens. Close attention to detail is constantly required: for example, the classic bird-mammal date (base of crown Amniota) has often been given as 310-315 Ma; the 2014 international time scale indicates a minimum age of 318 Ma.

Brazil. In the late 1970s, intense and sometimes acrimonious discussions between the recently established phylogeneticists/cladists and the proponents of the long-standing ‘gradistic’ school of systematics transcended specialized periodicals to reach a significantly wider audience through the journal Nature (Halstead, 1978, 1981; Gardiner et al., 1979; Halstead et al., 1979). As is well known, cladistis ‘won’ the debate by showing convincingly that mere similarity or ‘adaptive levels’ were not decisive measures to establish kinship. The essay ‘The salmon, the lungfish and the cow: a reply’ by Gardiner et al. (1979) epitomized that debate, deliberating to a wider audience the foundations of the cladistic paradigm, advocating that shared derived characters (homologies) support a sister- group relationship between the lungfish and cow exclusive of the salmon (see also Rosen et al., 1981; Forey et al., 1991).

Email: [email protected] urn:lsid:zoobank.org:author:55EA63EE-63FD-49E6-A216-A6D2BEB91B82 Abstract. The family-group names of animals (superfamily, family, subfamily, supertribe, tribe and subtribe) are regulated by the International Code of Zoological Nomenclature. Particularly, the family names are very important, because they are among the most widely used of all technical animal names. A uniform name and spelling are essential for the location of information. To facilitate this, a list of family- group names for fossil fishes has been compiled. I use the concept ‘Fishes’ in the usual sense, i.e., starting with the Agnatha up to the †Osteolepidiformes. All the family-group names proposed for fossil fishes found to date are listed, together with their author(s) and year of publication. The main goal of the list is to contribute to the usage of the correct family-group names for fossil fishes with a uniform spelling and to list the author(s) and date of those names. No valid family-group name description could be located for the following family-group names currently in usage: †Brindabellaspidae, †Diabolepididae, †Dorsetichthyidae, †Erichalcidae, †Holodipteridae, †Kentuckiidae, †Lepidaspididae, †Loganelliidae and †Pituriaspididae.

  • SCIENCE CHINA Cranial Morphology of the Silurian Sarcopterygian Guiyu Oneiros (Gnathostomata: Osteichthyes)

Based on those features, we restored, for the first time, the skull roof bone pattern in the Guiyu clade that comprises Psarolepis and Achoania. Comparisons with Onychodus, Achoania, coelacanths, and actinopterygians show that the posterior nostril enclosed by the preorbital or the preorbital process is shared by actinopterygians and sarcopterygians, and the lachrymals in sarcopterygians and actinopterygians are not homologous. The endocranium closely resembles that of Psarolepis, Achoania and Onychodus; however, the attachment area of the vomer pos- sesses irregular ridges and grooves as in Youngolepis and Diabolepis. The orbito-nasal canal is positioned mesial to the nasal capsule as in Youngolepis and porolepiforms. The position of the hypophysial canal at the same level or slightly anterior to the ethmoid articulation represents a synapmorphy of the Guiyu clade. The large attachment area of the basicranial muscle indi- cates the presence of a well-developed intracranial joint in Guiyu.

Long5, Michael J. Fagan1, Philippe Janvier6, Anthony Herrel7, Mathieu D. Santin8, Gaël Clément6 & Marc Herbin7 The neurocranium of sarcopterygian fishes was originally divided lengthens during prenatal development (Figs. 2, 3, Extended Data into an anterior (ethmosphenoid) and posterior (otoccipital) Fig. 1). The trabeculae extend anteroventrally to the notochord, and portion by an intracranial joint, and underwent major changes in delimit the open hypophyseal fossa. They fuse anteriorly as a narrow its overall geometry before fusing into a single unit in lungfishes trabeculae communis (Fig. 2, Extended Data Figs. 1, 2). Posteriorly, and early tetrapods1. Although the pattern of these changes is the ethmosphenoid portion develops around the anterior notochordal well-documented, the developmental mechanisms that underpin tip in the fetus; in later stages, it lies entirely anterior to the notochord. variation in the form of the neurocranium and its associated soft The notochord penetrates the ethmosphenoid portion at a position tissues during the evolution of sarcopterygian fishes remain poorly posterodorsal to the trabeculae, and terminates posterior to the hypo- understood.
