Where: Kalimantan, Indonesia (0.2° N, 117.4° E: paleocoordinates 0.2° N, 118.0° E)
• coordinate stated in text
When: Kutai Basin Formation, Late/Upper Miocene (11.6 - 5.3 Ma)
• Biostratigraphic data (large benthic foraminifera and calcareous nannoplankton) suggest that the TF 102 locality and other fossiliferous localities nearby are assigned a Tortonian age (Renema et al. 2015). Strontium isotope data from scleractinian corals and giant clams (Tridacninae) from six localities in the Bontang area (including TF 102) show ages ranging from 8.24 Ma to 9.75 Ma (+/-1 Ma) with an average of 9.4 +/- 0.2 Ma, matching a Tortonian biostratigraphic age.
Environment/lithology: marine; poorly lithified, graded, coarse-grained, silty claystone and gray, blue claystone
Size classes: macrofossils, mesofossils
• The most abundant mollusk taxon in bulk samples is a medium-sized (~10 mm) cerithiid (Fig. 3G). The second most abundant taxon is a comparatively large (~25 mm) turrid.
Collection methods: bulk, surface (in situ), sieve
• The first set of samples was obtained by handpicking every mollusk seen at the surface of each coral patch. One additional handpicked surface collection includes larger, well-preserved coral colonies, selected to complement the taxonomic inventory. Subsequently, two bulk sediment samples were collected from each patch, resulting in a total of 10 bulk samples with weights ranging from 3 to 6 kg. Bulk samples used for the study of mollusks were treated following the procedures outlined in Reich et al. (2014), assessing all mollusk remains retained on a sieve with a mesh of 1 mm.
