Merry Fossil Christmas 2017

This year's Christmas greeting image was created with specimens from two locations.

The star (thin section of crinoid stem), trunk (eroded crinoid stem), circular ornament (button coral) and drop shaped ornament (anchor crinoid stem) were obtained from the Devonian Period Jeffersonville/Beechwood/Speed Limestone of Clark County, Indiana USA. The anchor crinoid is a Ancyrocrinus sp. found in the Beechwood Limestone and the button coral is a Hadrophyllum orbignyi from the Speed Limestone.

The tree portion is an Atlantic Auger gastropod shell (Terebra dislocata) and the small fragment ornament is a broken piece of a sea urchin. Both of these specimens were found at Folly Beach near Charleston South Carolina, USA.


To visitors of this blog, I wish you a Merry Christmas and hope the new year brings you new finds in search for fossils in the world around you.

Atlantic Auger Shells

Working on this year's fossil Christmas tree which will partially not consist of fossils. I am using some specimens I collected while at Folly Beach near Charleston South Carolina USA in August 2017. The images in this post are of Common American Auger gastropod shells aka Atlantic Auger (Terebra dislocata Thomas Say, he originally named it in 1822 Cerithium dislocatum).

Unidentified fossil?

This image was sent to me recently and the sender asked if I knew what it was. It looks to me to be impressions left by plant stems or leaves. It was found in Breckinridge County, Kentucky USA. The county appears to be mostly in Mississippian Period surface rock but west of the county is Pennsylvanian Period rock.

If anyone has an idea of what this might be, please leave a comment or e-mail me at louisvillefossils@gmail.com. Thanks!
