Jurassic coral genera from ODP Site 639, Atlantic Ocean, west of Spain

Abstract

Twenty-three Jurassic corals from ODP Hole 639D are illustrated, described, and tentatively assigned to genera, from which a Late Jurassic age (Tithonian?) is suggested. Facies and sediment analyses indicate a soft-substrate habitat and that the bulk of the micrite seems to have been calcite originally. The corals, mostly colonial, are rather diversified, with a strong representation of stylinid and pennular forms. A single pennular colony from Hole 639C is also discussed. The enumerated taxa are Pseudocoenia sp., Stylosmilia cf. pumila, Stylosmilia sp., Enallhelia sp., cf. Dimorphastraea sp., Latomeandridae, Fungiastraea sp., Trocharea sp., Microsolenidae, cf. Dermosmilia sp., Calamophylliopsis(?) sp., cf. Thecosmilia sp., Lochmaeosmilia sp., and Intersmilia sp. -Authors
