This shady creek section might contain the Eocene/Oligocene boundary, which is rare a rare and important find if true.

To perform transects on the coral assemblages of the Top-reef
Stadion (TF51 & TF57).
On the 22nd June, the group conformed by Paul,
Emanuela, Nadia, Pak Untug, and Aseb settled in Samarinda. Soon after lunch, we
went back to Batu Putih (TF76) to have a look on the corals and looking for
bryozoans. Although an active quarry, the outcrop has not changed that much
from last year. Intact colonies of platy corals were observed upside down, and this
time we tried to collect the ones we left behind from last year, but again...
These thick coal beds lie within Middle Miocene (? according to Witts et all 2011, IPA Proceedings) Warukin Formation in the Barito Basin. Not all coals are this thick . . . today we logged a section that included a 1 m thick coal overlain by a marine transgressive mud with abundant small aragonitic molluscs. The fauna was dominated by protobranch bivalves typical of very fine grained organic-rich marine muds. Sorry, no seagrasses here (yet).
Greetings from the Barito Basin! Aries, Ken and Jon followed Verbeek’s original (1875) geological map overlain onto Google Earth to find the Pengaron locality, from which a great fauna of corals and poorer molluscs was originally described. Just at the right point on the map – a river bank section - we found a thin series (4m) of massive, hard, bioclastic limestones and sands with corals, molluscs, algal balls, a shark tooth and vertebrate material abruptly and concordantly overlying thin-bedded silty mudstones.
Following a 7h drive from Balikpapan to Bontang we had a brief tour around the most important outcrops visitted in December 2011. Especially in the central and northern areas 3 new and one old locality was cleared of vegetation. Already from the car when we jsut arrived we saw that TF110 had tremendously changed (see picture). In each locality enoirmous amounts of branching corals, molluscs and foraminifera where found.
Thank you, Fauzie!
…for inviting us, the Throughflow researchers, to the wedding of your daughter Inzie.
Dr. Fauzie Hasibuan is the responsible for the cooperation with our Indonesian Partner institute, the survei Geologi in Bandung. It was a great honor for us to join this wonderful and impressing event.
We arrived here a day before the NTA 4 starts (Paleoecology and interpretation of past environments).
After the shipment arrived in London and we dispatched the relevant crates to our colleagues around Europe, work has started to process Nadia Santodomingo and Emanuela di Martino’s coral and bryozoa specimens. We started by creating a reference collection of corals sampled in Java and Kalimantan by Ken Johnson on previous Throughflow field trips.
After some paperwork and phone calls
coordinating the delivery (thanks to Ken Johnson and Martin Munt), around 11 am
on Friday the container arrived to the Natural History Museum full of our Indonesian
fossils. The images talk by themselves…
Making the best of our strength together
with Ken, Bill, Lil, and Emanuela, the 44 crates were unloaded and stored
outside the conservation unit of the Palaeontology Department.
The crate for the Royal Holloway was sent on
Friday afternoon. Spanish samples will be dispatched soon.
