Fossils Found That Day, Part II

As you can see in the shot below, the finds were mostly Brachiopods and Horn Coral.

A good number Cyclonema were found. This is one of the only types of Gastropods (snails) on the site, that are shell replacements, rather than simply internal molds.

Here's a two-sided internal mold of a bivalve, possibly Modiolopsis.

There were plenty of the very attractive Bryozoan called Constellaria on the site. This bryozoan can be easily identified by the star-shaped monticules.

And NOW! Some of the trilobites we found. Quite a few tiny, but complete, Isotelus trilobites were found in the same layer found at Ceasar Creek.

Much bigger Isotelus trilobites were found, but they were too fragmented for reassembly. Here is a very nice genal area.

As for Flexicalymene, we know that at least 30 specimens were found that day. The picture below is of a prone trilobite. It's probably a molt, because the thorax segments are disarticulated.

Many members found two or three Flexi's. Here's one take-home numbering 11!.

There was a mix of tiny Flexi's, from the top of the Liberty Formation at this site, while the larger Flexi's are mostly from further down the cut in the Ft. Ancient of the Waynesville Formation.
