Petruny MS Thesis TDP Site 24B (Cretaceous to of Tanzania)

Where: Lindi, Tanzania (10.0° S, 39.6° E: paleocoordinates 31.1° S, 28.4° E)

• coordinate stated in text

When: Lindi Formation (Kilwa Group), Early/Lower Cenomanian to Early/Lower Cenomanian (99.6 - 93.5 Ma)

Environment/lithology: offshore; lithified siltstone and lithified, silty sandstone

• Like TDP Site 24, the dominant lithologies in TDP Site 24B are mm- to cm-thick, interbedded, dark gray siltstones and finegrained sandstones (Fig. 9). A light brown, fine- to medium-grained sandstone interval is visible between 5 m and 7.42 m. A few light gray, fine-grained sandy partings also appear throughout the cores. No bioturbation or fossils are observed.

Size class: microfossils

Preservation: original calcite, replaced with calcite

Collected by Tanzania Drilling Project Expedition in 2007; reposited in the USNM

Collection methods: core, smear slide,
