xml:lang="en"><p><italic>Palaeospondylus gunni</italic> Traquair, 1890 is an enigmatic Devonian vertebrate whose taxonomic affinities have been debated since it was first described. Most recently, <italic>Palaeospondylus</italic> has been identified as a stem-group hagfish (Myxinoidea). However, one character questioning this assignment is the presence of three semicircular canals in the otic region of the cartilaginous skull, a feature of jawed vertebrates. Additionally, new tomographic data reveal that the following characters of crown-group gnathostomes (chondrichthyans + osteichthyans) are present in <italic>Palaeospondylus</italic>: a longer telencephalic region of the braincase, separation of otic and occipital regions by the otico-occipital fissure, and vertebral centra. As well, a precerebral fontanelle and postorbital articulation of the palatoquadrate are characteristic of certain chondrichthyans. Similarities in the structure of the postorbital process to taxa such as <italic>Pucapampella</italic>, and possible presence of the ventral cranial fissure, both support a resolution of <italic>Pa. gunni</italic> as a stem chondrichthyan. The internally mineralized cartilaginous skeleton in <italic>Palaeospondylus</italic> may represent a stage in the loss of bone characteristic of the Chondrichthyes.</p></div></front><back><div1

Most recently, <italic>Palaeospondylus</italic> has been identified as a stem-group hagfish (Myxinoidea). However, one character questioning this assignment is the presence of three semicircular canals in the otic region of the cartilaginous skull, a feature of jawed vertebrates. Additionally, new tomographic data reveal that the following characters of crown-group gnathostomes (chondrichthyans + osteichthyans) are present in <italic>Palaeospondylus</italic>: a longer telencephalic region of the braincase, separation of otic and occipital regions by the otico-occipital fissure, and vertebral centra. As well, a precerebral fontanelle and postorbital articulation of the palatoquadrate are characteristic of certain chondrichthyans. Similarities in the structure of the postorbital process to taxa such as <italic>Pucapampella</italic>, and possible presence of the ventral cranial fissure, both support a resolution of <italic>Pa. gunni</italic> as a stem chondrichthyan. The internally mineralized cartilaginous skeleton in <italic>Palaeospondylus</italic> may represent a stage in the loss of bone characteristic of the Chondrichthyes.</p></abstract><kwd-group><kwd><italic>Palaeospondylus</italic></kwd><kwd>X-ray tomography</kwd><kwd>hagfish</kwd><kwd>Chondrichthyes</kwd><kwd>jawed vertebrates</kwd><kwd>chondrocranium</kwd></kwd-group><funding-group specific-use="FundRef"><award-group><funding-source><institution-wrap><institution>Australian Research Council Discovery</institution></institution-wrap></funding-source><award-id>DP110101127</award-id></award-group></funding-group><funding-group specific-use="FundRef"><award-group><funding-source><institution-wrap><institution>ESRF</institution></institution-wrap></funding-source><award-id>proposal EC690 and inhouse beamtime</award-id></award-group></funding-group><funding-group specific-use="FundRef"><award-group><funding-source><institution-wrap><institution>Swedish Research Council</institution></institution-wrap></funding-source><award-id>Vetenskapsrådet, 2015-04335</award-id></award-group></funding-group><custom-meta-group><custom-meta><meta-name>cover-date</meta-name><meta-value>July, 2017</meta-value></custom-meta></custom-meta-group></article-meta></front></pmc><affiliations><list><country><li>Australie</li><li>Autriche</li><li>France</li><li>Royaume-Uni</li><li>Suède</li></country></list><tree><country name="Royaume-Uni"><noRegion><name sortKey="Johanson, Zerina" sort="Johanson, Zerina" uniqKey="Johanson Z" first="Zerina" last="Johanson">Zerina Johanson</name></noRegion><name sortKey="Smith, Moya" sort="Smith, Moya" uniqKey="Smith M" first="Moya" last="Smith">Moya Smith</name><name sortKey="Smith, Moya" sort="Smith, Moya" uniqKey="Smith M" first="Moya" last="Smith">Moya Smith</name></country><country name="Suède"><noRegion><name sortKey="Sanchez, Sophie" sort="Sanchez, Sophie" uniqKey="Sanchez S" first="Sophie" last="Sanchez">Sophie Sanchez</name></noRegion></country><country name="France"><noRegion><name sortKey="Sanchez, Sophie" sort="Sanchez, Sophie" uniqKey="Sanchez S" first="Sophie" last="Sanchez">Sophie Sanchez</name></noRegion></country><country name="Australie"><noRegion><name sortKey="Senden, Tim" sort="Senden, Tim" uniqKey="Senden T" first="Tim" last="Senden">Tim Senden</name></noRegion><name sortKey="Trinajstic, Kate" sort="Trinajstic, Kate" uniqKey="Trinajstic K" first="Kate" last="Trinajstic">Kate Trinajstic</name></country><country name="Autriche"><noRegion><name sortKey="Pfaff, Cathrin" sort="Pfaff, Cathrin" uniqKey="Pfaff C" first="Cathrin" last="Pfaff">Cathrin Pfaff</name></noRegion></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
