5.54. 3
Doughty
Cave.
The west side of Doughty Cave is
made up of massive indurated
olive shale which rarely show
folding. The two ridges are
roche-moutoneed but in the hillside
about the old Doughty homestead
the splintering of the shale is
well shown trending N. 50° E.
The strike varies from
N. 30° W. in the north getting to
N. 42° W. in the middle & back to
N. 30° W. at the head of Doughty
Cove. At the head of the Cave just
west of the little brook a few
forams was collected:
Chonetes novascotiensis occ.
Dalmabella less common
Stenoscisma of borealis " "
The same species as are common
in the 5.54.2 shales.
These indurated shales are
overlain by still more indurated
shales exceedingly hard and very
fossiliferous, but unfortunately
the rocks too much baked by an
overlying gabbro sill and roche-
moutoneed to warrant collecting. A
few fragments were chipped off.
5.54. 3 B
Butterfaune include so far as
observed in the field:
Leptæna rhomboida 1/3 abundant
Stenoscisma of psilra common
Atrypa reticularis less common
