Abstract
Three distinct, rich neocomitid faunas occur in the Agrio Formation (middle Valanginian to lowermost Barremian). In the ammonite sequences between, neocomitids are very rare and limited to two thin horizons. The lower, upper Valanginian level has yielded Neocomites (Varlheideites) cf. peregrinus Rawson and Kemper, Neocomites (Varlheideites) sp. nov.? and Rodighieroites sp. which are widely distributed taxa. The upper level contains Comahueites aequalicostatus gen. et sp. nov., which appears endemic to the basin.
