Depositional Setting
The depositional environment of the Kaili formation is not entirely known, and there are two hypotheses for its formation. It may have been a nearshore marine environment with 'normal' levels of oxygenation; or it may have been a deeper water environment further from the shore, on the open continental shelf; in this setting oxygen would not be available below the surface layers of the deposited sediment. The trace fossil assemblages in the formation suggest that it was below wave base and reasonably well oxygenated.

Famous quotes containing the word setting:
“Many working mothers feel guilty about not being at home. And when they are there, they wish it could be perfect.... This pressure to make every minute happy puts working parents in a bind when it comes to setting limits and modifying behavior.”
—Cathy Rindner Tempelsman (20th century)
