Tropic Shale

It extends downward and is extensively exposed in the eroded flats.


Eroded Flats

Most of the fossils are found in association with the oyster layers,
which are similar in appearance to the light brown area in the foreground of the photo above.
In some places, the oyster shells comprise the entire surface.

several species of gastopods and of course, oysters. Coiled ammonites and sharks teeth may also be found.
