Holocephali

Authors: Brignon, Arnaud;
Abstract

Holocephali Les chimères (Holocephali, Chimaeroidei) ne sont représentées dans la faune kimméridgienne de Fumel que par une unique épine dorsale décrite par Sauvage (Fig. 15B) qui n’a pas pu être retrouvée dans les collections du MBA. Cette épine, que Sauvage attribua au genre Ischyodus Egerton, 1843, est recourbée postérieurement et porte des stries longitudinales peu marquées. Selon Sauvage, elle est aplatie latéralement et son bord postérieur présente un sillon et deux rangées de tubercules rapprochés, lisses et recourbées vers le bas. D’après la photographie donnée par Sauvage, ce spécimen présente des affinités avec les épines de chimères trouvées dans le Kimméridgien supérieur de Suisse attribuée à Ischyodus quenstedti Wagner, 1857, une identification fondée sur leur association avec des plaques dentaires appartenant à cette espèce (Leuzinger et al. 2017a, b). Le peu d’éléments diagnostiques offerts par l’épine isolée présentée par Sauvage, de surcroît aujourd’hui perdue, ne permet cependant pas une assignation spécifique précise. L’identification à Ischyodus sp. en nomenclature ouverte (Sigovini et al. 2016) proposée par Sauvage pour ce spécimen est donc conservée ici.
