As there is the dark Eagle Ford shale
above the Birdline, the Birdline itself
has dark lulls and lipinite, and the Mason
Shale may also have dark shales. We can
see why the Birdline has or much oil
where the descending crusts bring it.
The front called Linn Fox Knott may
depose the Main Strut. The slot of gastropods
is from the Main strut limestone.
