ITB Geological Engineering Team Excavated Almost Submerged Fossils from Saguling Reservoir
BANDUNG, itb.ac.id – A team from Geological Engineering, Faculty of Earth Sciences and Technology (FITB) ITB, recovered some buried fossils at Sirtwo Island, Sanguling. The team was tasked to move the fossils to a safer location due to the area being predicted to be submerged with the rising water level.
Previously, it was known that some fossils were discovered on an island in the middle of Sanguling Reservoir, West Bandung Regency. This discovery, which began with a report from a resident, then was inspected by a team from Geological Engineering ITB.
"The fossils were discovered by a local resident a few months ago. At first, we thought that we could delay the excavation process because the water level is still low and that we have a more urgent excavation project. Now the water level has increased more than 5 meters because of the monsoon season," said Alfend Rudyawan, Ph.D., one of the team members.
Alfend said that, after discussing this with other parties that were involved since the rediscovery of fossils in this area, such as IAGI, Geological Museum, and the local residents, it was decided that the excavation must be done quickly.

"Unfortunately, we found that some of the fossil parts have been salvaged by unknown persons. We lost all the teeth parts that are required for identification. The plan was to excavate the skull fossils as fast as possible with some adjustment to the weather condition. We were very surprised when we discovered that the fossil is much bigger than we had expected. The buffalo fossil left horn is still wholly attached to the skull. At that time, we received some additional help to race against the weather," he explained.

Currently, the fossils are being secured in a temporary storage location, awaiting the team from the Geological Museum for further analysis and restoration. He hopes that through this combined effort, we could gather additional knowledge and information about the area and expand the fossil catalog for both the current and future generations.
