Keywords .-L owervarcus Zone, Middle varcus Zone, Teeth, Scales, Squamation pattern, Phoebodus fastigatus. Abstract .-AL ower andbasal Middle varcus Zone (Givetian, Middle Devonian) vertebrate association consisting of chondrichtyan teeth and scales of the genus Phoebodus is documented for the first time from the Aragonian Pyrenees of Spain. This record suggests that different teeth morphologies that were previously treated as separate taxa could be grouped in Phoebodus fastigatus. Moreover, the teeth and scales association is in agreement with the previously recons- tructed squamation pattern of this taxon.
