Within Quarry #3, there were basically two sites, which we just called the "lower" and "upper" sites, since one was a bit uphill relative to the other, even though they were working the same set of strata. So the group split into two parts. I was in the lower site, which is shown here, along with Becky (front), Hailu and Christie (left), and Diane and Mike (center). One of the crew (right) watches us while on a well-deserved break. The quarry face is at the left sie of the picture -- in this area, the paper-thin shales of the Xiagou Formation have been tilted nearly vertically (seen behind Diane in the picture) by the same forces that pushed up the Qilian Mountains (India smashing into south-central Asia). So it's really just a matter of walking up to the outcrop, inserting a thin chisel blade, and peeling off layer after layer until fossils emerge! The shales tend to be pretty friable, though, so it's difficult to peel off big pieces before they break into smaller plates, which you can see littering the quarry floor here.
