Illymatogyra arietina Oyster Fossil

Here are some pictures of some recently found oyster fossils. They appear to be an Illymatogyra arietina (Roemer). The fossil was found in the Georgetown Formation of Austin Texas USA. Oysters like these lived in the Cretaceous Period. Thanks to Kenny for the images.

Archaeocidaris Sea Urchin Fossil

This image is of an Archaeocidaris sea urchin fossil. The animal existed in the Carboniferous Period. Fossil was discovered in Brown County Texas, USA. Fossil was on display at the Natural History Museum Vienna (Naturhistorisches Museum Wien) on August 2024.

I posted another specimen found at this locality in 2017 on display at Mace Brown Museum of Natural History is located at the College of Charleston South Carolina USA.

Richthofenia permiana Brachiopod Fossil

 

This image is of a Richthofenia permiana brachiopod fossil. The animal existed in the Permian Period. Fossil was discovered in Texas, USA. Fossil was on display at the Natural History Museum Vienna (Naturhistorisches Museum Wien) on August 2024.

This fossil is very strange, just looking at it I would identify it as a horn coral but it is a brachiopod. The label in the museum listed it as "tütenförmiger Armfüßer" which translates to bag-shaped brachiopod.  Learn more about this fossil at the blog  Equatorial Minnesota and its relation to Benjamin Franklin Shumard (1820-1869) at medical doctor from Louisville who switched to paleontology. This fossil might be under the genus Prorichthofenia now.

Diadectes phaseolinus Reptiliomorpha Fossil

This reptiliomorpha fossil was on display at the American Museum of Natural History (AMNH) in New York City in July 2018. The fossil was named Diadectes phaseolinus (Cope, 1880). According to GBIF (Global Biodiversity Information Facility), the accepted name for this fossil is Diadectes sideropelicus (Cope, 1878). The name means "crosswise biter".

UV Fluorescent Oyster Fossil

Recently, I obtained an ultraviolet (UV) LED flashlight set at 365 nm wavelength. This light is shortwave UV and in the past this type of light was quite expensive. I have a Mineralight Model SL 2537 which is over 50 years old. The replacement bulb for it is over $100. The LED light I found on Amazon.com was under $40. I was somewhat skeptical it would produce shortwave UV. It worked and I am glad now I have a replacement for the older light.

I illuminated some oyster fossils and they really started to fluoresce an orange color.

Below is an image showing two intertwined oyster fossils that appear to be Ilymatogyra arictina. It was found in the Del Rio Formation of Val Verde County, Texas, USA. It dates to the Cenomanian, Upper Cretaceous Period. I originally posted about this fossil on December 27, 2019.
