Quite a few of the solitary horn coral, Grewingkia, were
The Grewingkia horn coral below was sticking out
of the road cut as shown below. It just took a firm pull to free it. The cleaned
specimen is shown in the second picture.
Some were encased in rock and unrecoverable, as was the one
This horn coral has a beautiful splay of septa, caused by
being broken half away. Nice educational specimen. That's a

Another kind of solitary horn coral we found was the smaller Streptelasma.
It has a wider opening and usually has evidence that it was attached to

Here's one collection of Grewinkia and Streptelasma.

Another group shot. Mostly Grewingkia.
Another kind of coral found in abundance that day was the
encrusting colonial coral, Protaraea richmondensis. In the shot
below, it's covering a strophomenid Brachiopod.
And at least one specimen was found of the somewhat less
common colonial coral, Tetradium. This one is filled with calcite
crystals! Good find.
