Clark County Indiana Geodes

Here are the last of the pictures I found in the Kodak camera's internal memory. They are not of fossils but of a specimens that quite a few people look for on the Internet...GEODES. I think a number of members were picking up geodes at the quarry during the KYANA Geological Society field trip. Here are two that I opened up and contain quartz? or calcite?

Devonian Button Coral Hadrophyllum orbignyi

Yesterday's entry showed some recovered pictures from April 2008 KYANA Geological Society quarry visit. Here are two pictures I found on that camera of Devonian button coral that are from that quarry. They are called Hadrophyllum orbignyi (Edwards & Haime, 1851). These were found in the Speed Limestone in Clark County, Indiana. I have also seen them referred to as Hadrophyllum d'orbignyi in older literature. More images of these can be seen here: http://www.kyanageo.org/Fossils/devonian/coral/hadrophyllum-orbignyi.jpg http://www.kyanageo.org/Fossils/devonian/coral/RCL161_Hadrophyllum_orbignyi.jpg http://www.yale.edu/ypmip/taxon/anthozoa/rugosa/37141.html

A Good Reason to Join KYANA Geological Society

We did a little house cleaning and the USB Kodak transfer cable was found in a drawer. I have been looking for this cable for about a year because the some pictures from a geology field trip was stored in the Kodak digital camera's internal memory. So these pictures were taken in April 2008 as KYANA Geological Society had their quarry field trip into a local quarry located in Clark County, Indiana. The area of the quarry we went to that day was full of Devonian fossils (horn corals, colonial corals, byrozoans, Phacops trilobites, button corals, gastropods, and other fossils). We also found geodes and pyrite in the New Albany Shale layer.

Our society gets to collect there because we have group insurance and are conscious about safety. Hopefully, our quarry trips will begin soon now that the weather is warming up.
