Presencia de la icnoespecie Dactyloidites ottoi en el complejo de abanico costero de Sant Llorenç del Munt (Eoceno, Cuenca del Ebro, NE de España)

The presence of Dactyloidites ottoi is first recorded in the Eocene Sant Llorenç del Munt fan-delta complex. This constitutes the first citation for the Paleogene. The ichnospecies occurs in the lower part of a prograding fan-delta front sequence, associated to other traces produced by sediment-feed...

Descrição
Resumo:The presence of Dactyloidites ottoi is first recorded in the Eocene Sant Llorenç del Munt fan-delta complex. This constitutes the first citation for the Paleogene. The ichnospecies occurs in the lower part of a prograding fan-delta front sequence, associated to other traces produced by sediment-feeders. This association is substituted in the upper part of the sequence by abundant vertical Ophiomorpha indicating an increase of energetic conditions. The paleoenvironmental setting interpreted for Dactyloidites is consistent with that of previous described occurrences
