Abstract:
The majority of the bones in the quarry, aside from the sauropod, are fragmented. Although the sauropod shows little directional orientation, the disarticulated remains of the other animals show exhibit orientation that is consistent with both river current and wave activity.
Stratigraphy and sedimentology suggest that the bones accumulated on a delta plain during a period of drought. The bones were disarticulated and broken by wreathing processes and possibly by trampling. Bones were then reworked and oriented in distributary channels or by wave activity along the lake margin. Following the drought, the lake level rose and the bones are capped by a mudstone containing molluscs from the lake.
