Site 1: Fossils Found
Since we had a good rain the day before, the ground was still wet but not shiney. This is great because it makes the fossils color-coded. Can you spot the Cephalopod in the picture below? The crinoids at this site had a slightly pink color. The trilobites were brown. The Bryozoans were whitish pink or gray. The clay was blue-gray. The reddish coloring came from iron oxide indicating exposure to the air and/or ground water.
What are Greg and Dan doing up there? It looks like they found something!
Greg was meticulously collecting parts of a large colony of Constellaria florida Bryozoans , shown below in his cardboard tray. He will take this home and try to piece it back together with Superglue gel.
The shelf above where Greg was collecting was also littered with thousands of
ramose bryozoan fragments, just waiting for a collector to attempt their
Other bryozoans found were the cone variety named Prasapora simulatrix (above). Be sure to check the bottoms of these cones for the small rare trilobite, Primaspis. Click here (99k) for a picture of John Tate's example, found last year on a different Kope site in Northern Kentucky. It will give you an idea of how these Primaspis trilobites look on the bottom of Bryozoan cones.
Found, also, was this pavement of the brachiopod, Sowerbyella rugosa.
Lots of crinoid stems and calyxes of
Ectenocrinus simplex and
Cincinnaticrinus varibrachialus were found as shown below.
The above crinoid calyx is Ectenocrinus simplex
Also found were examples of the

were present at this site, just as they are on every site, as evidenced by the
many molt parts. In the shot below, you can see a

There weren't many reports of Dry Dredgers finding whole trilobites on the first site we visited that day. Here's one, below, that is so fragile, that it was not safe to remove the clay from the specimen on the site. It is likely to be a rare trilobite and extreme caution must be taken to keep it in one piece.
