Poking Around in the Waldron Shale
Recently, I got a rare opportunity hunt for fossils in the Waldron Shale and a number of fossils were found. Nothing earth shattering but it was fun to get out after a long absence to poke around and see some familiar fossil friends.
This first image is of a fragment of a Trimerus trilobite pygidium. Not sure if it is all there in at least one lobe is and probably also the middle section as well. The next image is of a very flattened Dawsonoceras cephalopod that is about 10 cm long.
No trip to the Silurian Period Waldron Shale fossil layer would be complete without seeing the index fossil. The crinoid Eucalyptocrinus must have been prolific on the seabed as the calyx cups can be spotted in just a short search time.
The last two fossils are a trilobite cephalons. I am not sure which trilobites they belong to (Dalmanites?).
UPDATE: Kenny informs the next image is of a flattened Trimerus trilobite. I agree with that ID.

Crassatella Pelecypod Fossil Evidence of Predation
The shell fossil in the first picture shows signs of predation probably from some sort of gastropod. These fossils appear to be Crassatella vadosus pelecypods (named by Morton 1834). They existed during the Cretaceous Period (about 70 million years ago). This fossil was found in McNairy County, Tennessee (Ripley Formation).
See their identification PDF at this LINK.

Caecum Micro Sea Snail Shell
Here is a magnified image of a Caecum sp. sea gastropod shell. It was found in 2014 during a diving trip to Key West Florida, USA. The specimen was about 2 km off shore in about 5 meters under the water. I do not think this is a fossil. Viewed under microscope with a 3 mm field of view.
Thanks to Kenny for the specimen and Herb for letting me use his microscope.

Digging the Past! Event at Falls of the Ohio State Park
Saturday was Digging the Past! A Celebration of Archaeology and Fossils Day at the Falls of the Ohio State Park in Clarksville, Indiana. It is an event that focuses on educational activities for public. I am not sure how many years I have been volunteering at this event but it is always a fun and educational event to attend. This year I got a lot of new scientific questions about minerals that I need to be ready to answer next year.
The fossil pile did not yield a lot of fossils but I did see a number of brachiopods people brought to me for identification. I saw a nice crinoid holdfast and beautiful Platystoma snail fossil with growth lines. The naturalist at the park showed me a Dawsonoceras cephalopod fossil someone left that was about 20 cm long. The Devonian fossil pile was stocked with lots of spirifer brachiopod fossils for visitors to take home. A number of trilobite and coral fragments could be found there as well.
The mineral pile was the usual big geology attraction. A number of visitors found flourite cube corners or cube clusters in purple, yellow, and bluish colors. The material is from a fluorite processing mill in southern Illinois that processed minerals from that area. Normally one sees four types of minerals: fluorite, barite, calcite, and sphalerite. The fluorite is usually purple, yellow or clear. Occasionally, green and blue fluorite will be found.
A persistent child collector found a nice pink-clear fluorite fragment.
