Stratigraphy of the Late Middle Eocene to Early Oligocene in the Bath Cliff Section, Barbados, West Indies

Site 803

“…Sample 130-803D-64X-CC tentatively is assigned from the Podocyrtis chalara to the Cryptoprora azyx Zones (Saunders et al, 1984, equivalent to the basal part of the Thyrsocyrtis bromia Zone of , which cannot be differentiated. The diagnostic taxa present in this sample include Eusyringium fistuligerum, Lithocyclia ocellus, Thyrsocyrtis triacantha, Thyrsocyrtis rhizodon, Dictyoprora mongolfieri, and Podocyrtis papalis.…”

“…Neogene radiolarian zones (after 700- Saunders et al, 1984) and Ceratolithus rugosus are present, but Amaurolithus spp. were not observed.…”

“…Sample 130-803D-59X-CC can be assigned to the Cryptoprora ornata Zone (Saunders et al, 1984, equivalent to the uppermost part of the Thyrsocyrtis bromia Zone of of the upper Eocene. This sample contains T. triceros, Artophormis balbadensis, Calocyclas turris, C. ornata, the Sethochytris babylonis group, Dictyoprora mongolfieri, Dictyoprora pirum, Dictyoprora armadillo, Lophocyrtis jacchia, and Lychnocanoma amphitrite.…”

The Calocyclas bandyca Zone (Saunders et al, 1984; equivalent to the middle part of the Thyrsocyrtis bromia Zone of of the upper Eocene is placed in Samples 130-803D-60X-CC through -63X-CC, based on the presence of T. bromia, C. turris, C. bandyca, C. ornata, and Cryptoprora azyx.…”

Introduction and Explanatory Notes

“…Radiolarian age determinations were based on the Cenozoic zonation of Riedel and Sanfilippo (1978) and subsequent modi fication in Saunders et al (1985).…”
