Limoptera cancellata Pelecypod Fossil

This pelecypod fossil appears to be a Limoptera cancellata. It was found in Clark County, Indiana, USA in the Jeffersonville Limestone. The fossil broke at the top and when apart one can see the lines from the shell going down into the matrix.

Thanks to Kenny for letting me image the fossil.

Large Horn Coral Embedded in a Fossil Fireplace

One of the largest horn coral fossils known to have existed was the Siphonophrentis elongata (Rafenesque & Clifford, 1820). When you find a piece of one these fossils you know it. It would be amazing to find one almost fully intact at this size. Fossil was probably found in the Jeffersonville Limestone of Clark County, Indiana, USA. This creature would have existed in the Devonian Period.

Second image is of the side view and is probably about 20 cm long and 8 cm in diameter.

This fossil is part of large collection of fossils that make up a large fireplace. The fossils are from a variety of places. Unfortunately, the creators of the fireplace have passed away making it difficult to determine the exact location of where this specimen is from.

A Bryozoan Fossil That Looks Like a Starfish

The Evactinopora quinqueradiata (Ulrich, 1890) bryozoan fossil is quite unique in that its cross section looks more like starfish than a bryozoan. This one is part of a very unique fireplace in Louisville, Kentucky, USA. It is made up a lot of fossils from a variety of places. Unfortunately, the creators of the fireplace have passed away making it difficult with identifications and where the specimens are from. The fossil was once part of the Lucien Pearson Beckner (1872-1963) collection. Colonel Beckner was director of the Natural History Museum at the Louisville Free Public Library.

The species was named by Edward Oscar Ulrich (1857-1944) in 1890 in the Illinois Geological Survey report.

Evactinopora grandis (Meeks & Worthen, 1868) bryozoan fossils like this are found in the Burlington Formation of Illinois and Missouri. This specimen is a five ray creature and at least 10 cm in diameter. It dates to the Mississippian Period (Osagean Series).

Thanks to Kenny for identifying this fossil.

 UPDATE (12-4-2022): This appears to be an Evactinopora quinqueradiata (Ulrich, 1890) and not the E. grandis (Meeks & Worthen, 1868). Learn more at http://lakeneosho.org/Evactinopora/quinqueradiata.html

Thamnoptychia Branching Coral Fossil - The Fossil Fireplace

I originally was just going to highlight the branching coral fossil in the center of the picture but 3 other fossils are cemented in close proximity to it. The enrolled trilobite in the bottom left corner of the picture appears to be an Ordovician Period Flexicalymene sp. They tend to be found closer Cincinnati, Ohio USA.

The main coral appears to be a Thamnoptychia sp. It was probably found in the Jeffersonville Limestone of Clark County, Indiana, USA. The fossil in the top right corner is base of a floating crinoid. It was known as an Ancryocrinus sp. and were found in the Beechwood Limestone. These animals existed in the Middle Devonian Period.

The bottom of center picture has a blastoid fossil. It appears to be a Deltablastus sp. blastoid. They date to the Permian Period and are usually found in the Timor of southeast Asia.

These fossils are part of a very unique fireplace exist in a house in the city of Louisville Kentucky, USA. It was created by local geology professor from various fossil finds throughout his lifetime. I took a number of pictures of it and will blog about them in the near future.

Hexagonaria Coral Fossil at The Fossil Fireplace

This appears to be a Hexagonaria sp. coral fossil. It was probably found in the Jeffersonville Limestone of Jefferson County, Kentucky or Clark County, Indiana, USA. These animals existed in the Devonian Period.

This fossil is part of a very unique fireplace exist in a house in the city of Louisville Kentucky, USA. It was created by local geology professor from various fossil finds throughout his lifetime. I took a number of pictures of it and will blog about them in the near future.

Cerithium Gastropod Fossil?

This internal mold of a gastropod fossil was given to me at a recent local geology meeting. The person who gave it to me said a batch of them was given to him by someone who thought they were from Missouri.

After doing some Internet searching I determined this fossil mostly like resembles the inside mold of a snail shell fossil being sold as a chalcedony or agate snail fossil from Morocco, Africa. I have seen it listed as found in the Atlas Mountains or Assa or Dakla Oued ed Dahab Lagouira in Morocco.

The fossil might date to the Eocene Epoch. It might be a Turtella or Cerithium. I thought it might be fluorescent but it did not under long wave ultraviolet light. Thanks to Dale for the fossil.

The Fossil Fireplace - Leptaena Brachiopods

A very unique fireplace exist in a house in the city of Louisville Kentucky, USA. It was created by local geology professor from various fossil finds throughout his lifetime. I took a number of pictures of it and will blog about them in the near future. I am looking for documentation on a number of the specimens before publishing the some of the more unique fossils. I thought I would start with something I have not seen before.

The Leptaena brachiopod is a familiar sight when studying fossils from the Paleozoic Era. I have found this fossil creature in Ordovician, Silurian, Devonian and Mississippian Periods rocks (a range of over 150 million years). What I have not seen is a large number of them in a mass mortality plate like the one pictured. I assume it is why it was chosen to go in the fireplace. A very nice find!

Gennaeocrinus kentuckiensis Crinoid Calyx Fossil

This fossil appears to be a Gennaeocrinus kentuckiensis (Shumard, 1866) crinoid calyx fossil. It was found in the Jeffersonville Limestone of Jefferson County, Kentucky USA. This layer dates to the Devonian Period (Givetian). Genus was named by Charles Wachsmuth and Frank Springer in 1881.

 Wow, this fossil has a very nicely preserved outer pattern!

Document used to identify the fossil was Memoir 16 The Devonian Crinoids of the State of New York by Winifred Goldring, The University of the State of New York, 1923. Page 558? description of plate 31 on page 228?. One of the specimens used to describe fossil is listed as from collection of Doctor Springer and found at Hamilton Shale of Falls of the Ohio, Louisville, Ky. Also listed is a American Museum Natural History number 4162 found at Bear Grass creek in Louisville, Ky.

Thanks to Kenny for image and discovering this fossil.

Thanks to Kenny for images and discovering them with his microscope.
