Loc. 47
Crawford Reach: Toe of spur just
east of Little Eagle road in
center E 1/2 E 1/2 NW 1/4 sec. 13, T. 19 N,
R. 26 E., the next spur N along
road from Loc. 46.
No good exposures here but an
abundance of fossiliferous cones.
from lower Trail City are weathering
out of lower part of spur. Various
parts of spur do not hang together
stratigraphically and are probably
successive slumps.
Locations 46 and 47 appear to contain both
individual PB and Gervillia cones
and cones in which the two
types of accumulation are joined
in single large cones.
A very few cones with dominance of
Pteris nebraskensis and Probecordia
in float. The Timber Lake beds and
concretions above the lower spurs
appear unfossiliferous here -
similar to section at Bullhead,
what governs distribution of the
Timber Lake marine fauna?
