Carbonates from before the regional mid-Middle Eocene basin forming unconformity are rare in SE Asia. The images shown here are reduced to about 1/5 their original resolution and highly compressed as JPG files. Original images available on request, as TIF files from 120 to 400 MB in size
- Kali Sana (PR-309), (480 KB). Limestone with Nummulites crasseornatus
- Jatibungkus Limestone (368 kb). A view of this limestone with Miscellanea specimens that date this carbonate as later Paleocene, not Late Eocene as in published accounts. This limestone is an olistolith about 70 metres thick and half a kilometre long within turbidites of Middle Eocene age in south Central Java.
- Jatibungkus Limestone (572 kb). A wide view of a different sample to that above. This image is of the more common nummulitic facies where the fauna is dominated by a species of Ranikothalia identified by the inflated marginal cord. Also present are many specimens of the alga Distichoplax biserialis with its distinctive biserial form, sometimes herring-bone in cross section. Rarer in the sample are fragments of the equally distinct solenoporacean alga Parachaetetes with nodular growth and subquadrate texture of the cellular tissue. All these three genera are no younger than Paleocene.

Barune Sandstone, Campanian of Papua New Guinea (522 KB). This sample is from the same location studied by Glaessner (1952, 1960) and other workers, from a small outcrop near Port Moresby. Glaessner (1960) gave a Campanian age to the Barune Sandstone based on the presence of Pseudorbitoides israelskii and Orbitoides tissoti, with thin sections also showing double keeled Globotruncanid and biserial heterohelicid types.
