| Abstract |
The osteology of IIchthyotringa africana from the marine Upper Cretaceous of the Eurafrican Mesogeais studied and the systematic position of Ichthyotringa discussed. Four apomorphies prove that this genusbelongs to the Aulopiformes: the presence of postero-medial processes on the pelvic bones, the epipleural seriesbeginning from the first vertebra, the first epipleurals located at the level of the horizontal septum, and the preuralneural spine 1 reduced and spatulate. The lengthening of the snout, the very large buccal cavity, the development ofthe palatine and pterygoid dentition, and the premaxilla and maxilla bordering the gape are four characters whichrefer Ichthyotringa to the Enchodontoidei. The numerous plesiomorphies kept by this fish and its rare apomorphies show that it is one of the most primitive genera within the suborder. |
