heavy bedded dense crystalline crinoidal limestone in
which also occurs Syphidula pulestro.
Higher the blue limestone is in thinner beds and
their
gradually introduces more chert and goes a dull shale.
Up to the Archolina bed the thickness is 44 feet
I saw no guide from these beds,
[illegible]
Above the Archolina given the limestone are also this
bedded dense crinoidal, measuring for 43 feet. This then
is the contact with the Beecroft.
The Beecroft is a series of heavy bedded darker
with chert
and more crystalline limestone than the New Scotland
below. [illegible] has collected two specific concerns
Syphidula pseudopulestro (the specimen does not show
of the smooth exterior) and so by Dalmanite's
tail. Thickness about 23 feet.
Then follows a great mass of black bituminous smelly
shale that weathers down into a
blocky cherty
material, which would begin in a 20 inch thin joint line.
The lower 30 feet almost all shale. Then 12 feet
of cherty then bedded blocky material. Then 6 feet of
blue shale followed by 12 feet of blocky material. Then
6 feet of more cherty material that weathers out into
greyish cherty blocks. Two faults then came in and a
