The Kope formation is good for nicely preserved Cephalopods, and and it was true for this site. Here's a couple of pictures of some that were found.

The ground was covered with Bryozoans in spots (see pic below).

The best Bryozoan find of the trip was this beautifully preserved Escharopora falciformis, which was likely found near the top of our site, in the Fairview Formation, or in some material that was pushed down the hill.

Another nice to find was this Bryozoan Batostoma with holes left from the interesting animal called Catellocaula vallata. This animal is interesting because it may be a Chordate, thought to include vertebrates!

Here are some more Bryozoans found that day, interesting just for their various shapes.

Worm Tubes

This site turned out to be great for unusually large specimens of the annelid worm tube, Cornulites and other Cornulitids. These worms attached themselves to crinoid stems in most of the examples we see from this site. Here's a few.

Another way worm tubes attached was to share a substrate with Bryozoans. Here's one of many examples we saw that day.
