In extensional flow fiber tended to perpendicularity to the streamline, while in shear flow and convergent flow fiber tended to parallel to the streamline in the thin wall caving.
The initially discovered RDBs include depositions at the paleo-tide convergent flow and the paleo-flood tidal jet, fringing deposition around the palco-terrance.
Crab yellows are stuffed into the rolled dough. When the two fingers are pinched, the dough will fit together and wrap the crab yellows completely inside, just like a half-blooming and half-convergent flower.
