Where: Lindi, Tanzania (10.0° S, 39.6° E: paleocoordinates 29.1° S, 29.3° E)
• coordinate stated in text
When: D. concavata, M. schneegansi, H. helvetica, & W. archaeocretacea foram zone, Lindi Formation (Kilwa Group), Early/Lower Turonian to Early/Lower Turonian (93.5 - 89.3 Ma)
• formation-level stratigraphic resolution
Environment/lithology: offshore; lithified claystone and lithified, silty claystone
•and claystones, with common, finely-laminated, possibly organic rich
•intervals (Figs. 7e and 9). Two intervals with light gray, well lithified siltstones and cross-cutting sulfate–carbonate veins are visible in cores TDP31/22 and 24. Light gray, fine-grained sandstone partings are present sporadically from 28 m to the bottom. Yellowish brown, mm- to cm-sized sand nodules occur occasionally through the middle and lower intervals of the hole. Ammonite and inoceramid debris are relatively frequent in the same intervals
•(Fig. 9). Slightly inclined lamination, indicative of moderate soft sediment
•deformation, is present throughout the hole, but is less common than at TDP Site 30.
