... of the bed. The largest, most complex and most complete bones are found near the base of the deposit, often in clusters of partially related elements, although this relationship may vary laterally. The densest accumulation of bone is commonly found in the middle third of the bonebed. The top 10–20 cm...

.... A striking feature of the Mowry is the large amount of disarticulated fish scale and bone present on bedding planes of slabs of weathered rock. The source of the silica in the Mowry is not completely understood. The venerable Rubey (1928) hypothesis that the silica was added directly by volcanic ash...

Geochemical-sedimentologic evidence suggests that potential oil source beds are and have been deposited in the geologic past in four main anoxic settings as follows. Large...

...) and the downside (FWS: flipside weathering stage) bone surfaces were examined in SU7 bones in order to estimate assemblage stability before burial (after Byers, 2002 ). Generally, bones with advanced MWS (stage 2 or more) and low FWS (stage 0–1) were subjected to little or no movement before burial and thus...

... the remaining 20%. Local coal beds reportedly have a high bone content ( Brownsfield, 1981 ). The coarse- and very coarse-grained sandstones exhibit large sets of high-angle cross-beds and contorted cross-beds. Cross-bed sets in the Tyee Formation average 3 to 10 ft (1 to 3 m) in thickness and range up to 33 ft...

Thin-bedded lime mudstones with prominent burrows formed farther updip to the north and west. Thick intervals of oolite and of shallow-water lime mudstone interbedded...
