Taballar (Miocene to of Indonesia)

Where: Borneo, Indonesia (1.8° N, 117.8° E: paleocoordinates 2.7° N, 121.1° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: N4 - N5 foram zone, Taballar Formation, Aquitanian to Aquitanian (23.0 - 16.0 Ma)

• From Wilson et al. 2007: Taballar overlies Mangkabua and underlies Birang. Te to Tf1 from the revised East India Letter Classification scheme based on larger benthic foraminifera from Adams, 1970; Lunt and Allan, 2004). Wilson et al report mollusks only from the top of Te5.

• formation-level stratigraphic resolution

Environment/lithology: mudstone and wackestone

• The deposits are interpreted to have formed in low-energy environments based on the predominance of micrite and the common common occurrence of thin and delicate fossils (Wilson and Evans, 2002). A varied shallow-water, stenohaline biota, including fragmented branching corals, large perforate foraminifera, and coralline algae is present throughout much of the succession. These fossils indicate deposition within the photic zone, and that the platform top predominantly experienced normal marine salinities (Wilson and Evans, 2002). Possible salinity fluctuations are inferred from the low diversity of biota and the local abundance of miliolid foraminifera in some beds (cf. Murray, 1991).
• It is largely composed of low-energy micritic mudstones, wackestones, and packstones with variable, low-angle dip. Wilson & Evans report gastropods from packstone and wackestone, but not mudstone.
