CONT

La plupart des actinoptérygiens modernes ont une queue homocerque, c'est-à-dire que le lobe du haut et le lobe du bas sont presque égaux et symétriques, comme par exemple la queue du saumon. Par contre, [les espèces du genre] Cheirolepis avaient une queue épicerque, c'est-à-dire que l'axe de [leur] corps se poursuivait dans un lobe supérieur plus développé.
