    An extraordinary gobioid fish fossil from Southern France. by Christoph Gierl, Bettina Reichenbacher, Jean Gaudant, Dirk Erpenbeck, André Pharisat

    Published 2013-01-01
    “…Several lineages, including the Eleotridae and Butidae, remain difficult to characterize because synapomorphies are rare (Eleotridae) or have not yet been determined (Butidae). Moreover, the fossil record of these groups is scarce.<h4>Results</h4>Exceptionally well-preserved fish fossils with otoliths in situ from uppermost Oligocene sediments (≈23-24 Mio. y. ago) in Southern France provide the most in-depth description of a fossil gobioid to date. …”

    The homology and function of the lung plates in extant and fossil coelacanths by Camila Cupello, François J. Meunier, Marc Herbin, Philippe Janvier, Gaël Clément, Paulo M. Brito

    Published 2017-08-01
    “…Abstract The presence of a pulmonary organ that is entirely covered by true bone tissue and fills most of the abdominal cavity is hitherto unique to fossil actinistians. Although small hard plates have been recently reported in the lung of the extant coelacanth Latimeria chalumnae, the homology between these hard structures in fossil and extant forms remained to be demonstrated. …”
