Masingini Beds, Tanga-Pangani, Tanzania - Schluter (1997) (Miocene of Tanzania)

Where: Tanzania (6.2° S, 39.2° E: paleocoordinates 7.0° S, 37.0° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Masingini Formation, Early/Lower Miocene (23.0 - 16.0 Ma)

• Miocene strata. Based primarily on the basis of foraminifera (listed). Macrofossils hint at a Pliocene age. Original age determinations such as Stockley (1928) were Pliocene.

• bed-level stratigraphic resolution

Environment/lithology: marine; argillaceous sandstone and shelly/skeletal limestone

• A range of carbonate and siliciclastic environments are present on Zanzibar, including reefal and open marone.
• Clayey sands and subordinate limestones, marly sands and fossiliferous limestones.

Size classes: macrofossils, microfossils

Preservation: original calcite

Collection methods: quarrying,

• Taxa mentioned informally in text from stratigraphic unit. Further data provided in Stockley (1928).
