and different from those of 8.
fing in 7. Fossils are very scarce here and the few one get are,
All of the strata of 6 to 9, both inclusive are once or less
magnesian limestones and some are dolomites. They are all very
much alike, leary bedded, dense, every bedded a little grey
to dark colored limestones. In zone 6 there are some thin
bedded strata.
In it occurs much mud-cracked material. One shot
was mud cracked and had two cells marked though ripples,
In some of the cells coarser cracked to the material was
seen. There is much evidence for very shallow seas. Even
in this zone are seen fossils but far less than in zone
8. A pebble conglomerate was also seen in zone 8.
In zone H or certain beds the fossils are rather out in relief
in a semi-silicious condition. However they are are as a rule
very firm. The surfaces of such limestones are covered with
a net work of raised faccid like strings of ball signs. What these
represent I can not say. On first picture one does not see
them, they come out in weathering.
In zone & the leary bedded dolomites are much domal
sometimes only 6 inches high and then 2 feet across and then the
domes may be 2 feet or more high and from 6 to 10 feet in
diameter. Usually on these domes appear thin bedded
material. The latter are very local.
And if one fossils today come from 8. A few from 7
are mixed with them. If we get any from upper part of
below they are just about like the others.
