Ostéologie de Clupavus maroccanus(Crétacé supérieur du Maroc) et considérations sur la position systématique et les relations des Clupavidae au sein de l'ordre des Clupéiformes sensu stricto (Pisces,Teleostei)

Osteology proves definitively that Clupavusmaroccanus is a typical Cluepoid (lateroparietal skull, ethmoidean and fronto-occipital fontanels, recessus lateralis, latero-sagittal fronto-parietal crest, clupeid ural complex, etc…). Clupavus represents a particular non-serrated family, the Clupavidae, different from the Dussumieriidae and the Congothrissidae, the two other primitive non-serrated Clupeoid families. Nor is Clupavus the ancestor of these two families. The systematic position and the relationships of the Clupavidae within the order Clupeiformes sensu stricto are discussed.
