Darriwilian species of Histiodella (Conodonta) in the Argentine Precordillera
The Middle Ordovician successions in the Central Precordillera of Argentina are characterized by carbonate and fine mixed carbonate/ siliciclastic deposits. Two middle Darriwilian sections spanning the Eoplacognathus pseudoplanus to Eoplacognathus suecicus Zones were sampled for conodonts, among whi...

The Middle Ordovician successions in the Central Precordillera of Argentina are characterized by carbonate and fine mixed carbonate/ siliciclastic deposits.
