Siphonophrentis gigantea Horn Coral on Display in Paris

 

I revisited pictures from my trip to Paris in 2016. This set of fossils are special in that they were found at the Falls of the Ohio, Clark County, Indiana USA. It was on display at the Muséum National D'Historie Naturelle Jardin Des Plantes Paléontologie et Anatomie Comparée in Paris France.The fossils were identified as Siphonophrentis gigantea (Lesueur, 1821). They are now known as Siphonophrentis elongata (Rafinesque and Clifford, 1820). Fossils date to the Middle Devonian Period.

You can see a picture of this fossil from 2009 in this posting:

The genus was renamed from Zaphrentis to Siphonophrentis by Dr. Marjorie O'Connell in 1914. Click on her name to read about her interesting yet short career in paleontology I wrote about March 2021.

Carpoid Fossil?

 




My cousin Kenny recently found this fossil in an Ordovician Period area of Indiana USA. Not sure what it is, maybe a worn carpoid fossil?

Calymene Pygidium & Thorax Trilobite Fossils

 



These pictures are of two trilobite fossils found in the Waldron Shale. They appear to be the pygidium and thorax remains of two Calymene (Brongniart, 1822) trilobites. These creatures existed in Silurian Period seas in what is now known as Clark County, Indiana, USA.

Phacops rana Trilobite Fossil Pygidium

 


Recently, I was looking for a trilobite in the Jeffersonville Limestone of Clark County, Indiana USA. I did not find one, at a mostly intact one that is. The best I could do was find this fragment of limestone with part of what is probably a Phacops rana (Green, 1832) fossilized pygidium. Also seen in this piece of limestone is an unidentified bryozoan fossil. These fossils date to the middle Devonian Period.
