Special Specimens

Showcasing special specimens here. 

There is a great diversity of specimens here in the quarry. Over 100 different species have been found to date with the greatest diversity found in the south wall section of the quarry where several bioherms have been discovered. There have been many finds with multiple species on a single plate or one species attached to another as epifauna. We will showcase those special finds on this page.

Here is a great example of a multi-species plate showing the predatory nature of  a brittle star attacking a crinoid that has fallen victim to a mudflow that has knocked it and several other specimens over. The large crinoid is a Ichthyocrinus laevis. There is also a Callocystites jewetti  on the top center of this plate. The smaller crinoid is a Lecanocrinus macropetalus.
The brittle star is a Protaster sp.

Bryozoan as an Epifauna

The coral is Favosites parasiticus, the bryozoan is a Hallopora aspera.  This specimen is 3" tall.

Howella crispa

Here is the brachiopod Howella crispa with a bryozoan, Fistuliporoid, attached to it as epifauna.

Trematopora tuberculata

Here is a fine specimen that I was able to clean out the center of the bryozoan to show the internal wall structure.

Three species plate!
Picture
Here is a very rare find of a plate with three different species on it.The cystoid is Callocystites jewetti. The crinoid is Crinobrachiatus brachiatus. This is by far and away the best Crinobrachiatus specimen found to date from the quarry. The Callocystites is attached to a bryozoan Chilotrypa ostiolata.
