Shuitangba is an open-pit lignite mine located in the Zhaotong Basin of northeastern Yunnan Province of China. While the coal mines of this area have long been known to hold an abundance of fossils, the first systematic survey of the Shuitangba site wasn’t launched until 2007.
That survey, conducted by
Denise Su, Nina Jablonski and Ji Xueping explored the fossiliferous sediments of Zhaotong Basin. Its success led to formation of the
Zhaotong Paleontological Research Project, lead by Jablonski, Su, Ji, Jay Kelley and Lawrence Flynn.
Shuitangba is dated to the end of the Miocene, about 6.1 million years ago, and has thus far yielded hundreds of specimens of animals and plants, including a relatively complete cranium of a juvenile ape that belongs to the species
Lufengpithecus lufengensis.
Preservation of the fossil plants and animals at Shuitangba is excellent. The diversity and abundance of specimens means that it has potential to provide more understanding about the environment during the latest part of the Miocene in southern China, and the evolution of the plants and animals found there.
Shuitangba is in a heavily populated area and the site is surrounded by rice paddies.
Rice harvesting...the traditional way.
In the field
Unlike at Laetoli or Woranso-Mille, all specimens are found in situ and need to be excavated rather than collected from the surface.
In the field
The specimens uncovered are extremely fragile and most require consolidation before removal from the ground.

In the lab
Many of the specimens need to be plaster-jacketed due to their fragile nature. They are then cleaned and prepared in the field lab before being taken to the Yunnan Cultural Relics and Archaeological Institute to be stored and curated.
