All of the previous pictures were of Articulate Brachiopods. There were a number of kinds of Inarticulate Brachiopods found that day too.
Here's a beautiful specimen of Trematis.
This next picture is also Trematis, but shows the flatter
Here's a close-up of the above Trematis (below).
Another, more common genera of Inarticulate Brachiopod found was Petrocrania.
In the next 3 pics, they are found encrusting the Brachiopod, Rafinesquina.
In this first picture, we see Petrocrania encrusting a Petrocrania,
encrusting a Rafinesquina! The game begins. How many layers of
Petrocrania encrusting Petrocrania can YOU find????
Notice in the Petrocrania above, the amorphous inarticulate was taking on the ridge pattern of it's host brachiopod.
No crinoid calyxes were found that day, at least that I know about. But
here's a nice crinoid holdfast, called Lichenocrinus found that
day. (The second photo is a close-up of the same specimen.)
