Halysites catenularia Chain Coral Fossil

 

This image shows a Halysites catenularia (Linnaeus, 1767) chain coral fossil. It dates to the Silurian Period and was found Kentucky USA. While I am guessing it was probably found at the Falls of the Ohio. It was displayed at Muséum National D'Historie Naturelle Jardin Des Plantes Paléontologie et Anatomie Comparée, Paris, France. Image taken August 2009.

The side view is has some green coloration maybe from moss from the Ohio River. It was from the Jules Marcou (1824-1898) collection. Marcou was born and educated in France and worked as a geologist for the Jardin des Plantes during the late 1840s. He traveled on expeditions in the United States during this time and in the early 1850s. So he could have acquired this fossil then. He later settled in Massachusetts USA, became a citizen and died there.

Porpoceras ventricosum Ammonite Fossil


This image shows a Porpoceras ventricosum (Buckman , 1914) ammonite fossil. It dates to the Jurassic Period (Toarcien) and was found at Anduze (Gard) France.

French Harpoceras serpentinum Ammonite Fossil

The image shown is a Harpoceras serpentinum (Schlotheim , 1820) ammonite fossil. It dates to the Jurassic Period (Toarcien) and was found at Cheville (Sarthe) France. It was displayed at Muséum National D'Historie Naturelle Jardin Des Plantes Paléontologie et Anatomie Comparée, Paris, France.  Image taken August 2009.

The species was named by German palaeontologist Ernst Friedrich, Baron von Schlotheim (1764-1832). He originally called it Ammonites serpentinus (Schlotheim , 1820). The name ammonite was derived from Egyptian deity Ammon who was represented by a symbol looking like a coiled ram horn.

French Hildoceras bifrons Ammonite Fossil


Above is an image of an Hildoceras bifrons (Bruguière, 1789) ammonite fossil. It dates to the Jurassic Period (Toarcien) and was found at La Verpilliere (Isère), France. It was displayed at Muséum National D'Historie Naturelle Jardin Des Plantes Paléontologie et Anatomie Comparée, Paris, France.  Image taken August 2009.

The species was named by French zoologist Jean Guillaume Bruguière (1749-1798). While the name ammonite was derived from Egyptian deity Ammon who was represented by a symbol looking like a coiled ram horn.  In medieval England, the fossil was seen by some as a petrified coiled snake. The genus of this ammonite is associated with St. Hilda of Whitby, Yorkshire, England. Legend has it she turned a plague of snakes to stone. As such an American palaeontologist Alpheus Hyatt (1838-1902) named an ammonite genus Hildoceras (Hyatt, 1876) after her.

Oxinpes Foraminifera Fossil

Images taken from microscope of the foraminiferan fossil. This fossil was identified as an Oxinpes. It was found in the Beechwood Limestone just below the New Albany Shale. That layer dates to the Devonian Period. The locality was Clark County Indiana USA. This was a picture I took over 10 years ago from one of Dr. Conkins microscope slides. It was never used in publication and was a demonstration on how to use Adobe Photoshop to stack the microscope images, add the scale, and print directly to make a copy ready page for printing.

Images taken from microscope of the monotypic agglutinate foraminiferan fossil. This fossil has been identified as an Inauris tubulata (Conkin, Conkin & Thurman, 1979). It was found in the Jeffersonville Limestone that dates to Devonian Period. The locality was the Gilmore Quarry, Utica Indiana USA. This was a picture I took over 10 years ago from one of Dr. Conkins microscope slides. It was never used in publication I far as I can recall.

Possible Fish Scale Fossil - Devonian Period


Pictured in this posting is a mystery fossil found in the New Albany Shale (Late Devonian Period). It was uncovered by splitting a nodule of shale. Size of fossil is  about 4 mm wide. Specimen was collected in Floyd County, Indiana, USA. It might be some sort of fish scale. I need to get some better microscope pictures of this fossil. The specimen somewhat resembles a Rhabdoderma scale (see the discussion at this link Mazon Creek Coelacanth scale).

Greererpeton burkemorani Fossil


This cast of a fossil was displayed on August 2022, at the Harvard Museum of Natural History in Cambridge, Massachusetts, USA. An extinct tetrapod fossil is called Greererpeton burkemorani (Romer, 1969). The cast made of the specimen that was found at Greer Quarry, Decker's Creek Monongalia County West Virginia USA. It dates to the Mississippian Period. Genus first described by Alfred S. Romer in 1969. The species appears to be named after a Cleveland Museum of Natural History paleontologists John J. Burke and William E. Moran who uncovered fossils like this at Greer Quarry (the type locality).

https://mczbase.mcz.harvard.edu/guid/MCZ:VP:VPRA-4348 its record shows collector as CMNH which I suppose means Cleveland Museum of Natural History. So this might be a cast of one of their fossils. Visiting their web site, I found a 3D model of a different specimen CMNH 11093 from the same West Virginia locality.
