It wasn't a gende stream, because the animal's right leg was dislocated and moved back behind the skeleton. It might have taken a relatively good current to flip that big right leg over, though if the carcass had been bloated with gas as it rotted, the bones might have been more easily turned. The current quickly brought in sediment to cover the bone and keep it from eroding while it slowly fossilized.
The current in the sandy bottom of the stream channel wasn't so strong that it disturbed the largest elements of the skeleton. But it did wash many bones out of position. The left upper arm was pushed several feet away. That's the bone that Kathy Wankel found first. The four-and-one-half-foot-long skull had separated from the jaws, which still held several thick serrated teeth, each half a foot long.
The skull had rolled up against the pelvis. The right rear leg had toppled over, and its bones had separated. We found the left leg a year later when we began cleaning the pelvis. The pelvis had washed over it.
