Thecideid brachiopods are poorly known brachiopods of debated phylogenetic relationships which occur from the Late Triassic to the Recent. Extensive thin section analysis of circumalpine Paleogene carbonates (Late Eocene of Austria as well as the Early Oligocene of Slovenia, the Inntal Valley and Northern Italy) has revealed the presence of thecideid brachiopods allowing for the analysis of their taphonomy, component relationships and facies distribution.

Abstract

Thecideid brachiopods are poorly known brachiopods of debated phylogenetic relationships which occur from the Late Triassic to the Recent. Extensive thin section analysis of circumalpine Paleogene carbonates (Late Eocene of Austria as well as the Early Oligocene of Slovenia, the Inntal Valley and Northern Italy) has revealed the presence of thecideid brachiopods allowing for the analysis of their taphonomy, component relationships and facies distribution. These brachiopods are most commonly associated with corals and coralline red algae, included within complex encrustation sequences. Their paleoecology closely mirrors that of Recent and fossil thecideid species which are characteristics of cryptic habitats in tropical and warm temperate seas.
