Near the boundary of 5:51, 4 the
shale is formed for about 10 yds.
along the line of strike of some
sediments. These strike N. 22° W., dp.
28°-30°. The rock is a couple of feet
of banded shale weathering in
banded agglomerate fashion
and underly a couple of feet of
monotonous shale. The top of
the first contains at one place
a cluster of Conchidium
knighti, while a couple fads
of the same occur on the same
surface & a few inches higher
the same form as 5:51, 5a.
The fossils observed here are:
Plectambonites occasional
Leptena rhomboidalis common
Chonetes cornutus
Dalmanella (conn.) occasional
Stenoscisma cf. acinus common
Wilsonia wilsoni occasional
Meristella (new large) "
Atrypa rugostriata-marginata "
Spirifer crispus small "
Kionoceras myrice rare
Favosites ?pyramidalis "
These shales appear to overtly a
base flow which occurs along the
left side less than fifty feet back
from the shore. If this be so, the
shale probably fill the gap between
the two brooks. See section 5:51, A
