Abstract

In southern Iberia (southern Iberian chain and Prebetic Zone) the Cenomanian to Turonian transition is characterized by a sedimentary succession of very shallow marine carbonates with abundant evidences of subaerial exposure and paleosols (Alarcón Fm.). That succession records the oldest known Microcodium in Iberia. Its first appearance is abrupt and probably related to the environmental changes associated to the global perturbation in the C cycle that trigger the oceanic anoxic event OAE2.
