Here is a picture of an Echinocorys sulcatus (Goldfuss, 1826) echinoderm fossil found in Haidhof near Ernstbrunn Austria. The fossil dates to the Paleocene Epoch. Fossil was on display at the Natural History Museum Vienna (Naturhistorisches Museum Wien) on August 2024.

Echinolampas hoffmani Enchinoderm Fossils

This image is of an Echinolampas hoffmani (Desor, 1847) enchinoderm fossils. The creatures existed in the Pliocene Epoch of the Neogene Period. Fossila were discovered in Parlascio, Toscana, Italy.

Echinocorys Echinoderm Fossil

This image is of a sea urchin fossil called Echinocorys.  The shell once consisted of calcite but has since been replaced by crystalline silica. This animal lived in the Cretaceous Period. The fossil was found at Sidmouth, Devon, England.

This specimen was on display August 2016 in Natural History Museum of London, England.

Encope micorpora Echinoderm

College Ave, Tempe Arizona 85281) I saw fossil specimen (AHS-NH#9854) Encope micorpora (Agassiz, 1841) sand dollar. Creatures like this are alive today and existed back to the Pliocene This one was found in El Golfo, Mexico.

Bicidiocrinus wetherbyi Crinoid Calyx

Over the weekend my cousin went fossil hunting in Grayson County, Kentucky USA for Mississippian Period fossils. He got extremely lucky and found a nice crinoid calyx. It appears to be a Bicidiocrinus wetherbyi (Wachsmuth and Springer, 1886). It was found in the Glen Dean formation.

 

A retired professor at the University of Kentucky, Dr. Don Chesnut has a number of posted images on the Internet that were used to help determine the identify of this specimen. See links to pictures from his Masters thesis on the Mississippian echinoderm Bicidiocrinus (Strimple, 1975) from the Sloans Valley member below:

Thanks to Kenny for the images for this blog posting!

Here is another nice crinoid calyx found in this same formation:

Onychaster Starfish Fossil

Onychaster sp. starfish fossil that crawled the seafloor in the Mississippian Period. This fossil is on display on the first floor of the Indiana State Museum as of May 2012. More than likely this fossil is from Crawfordsville, Indiana. That is a some beautiful 3-D prep work!

Echinocorus vulgaris

This fossil is called Echinocorus vulgaris from the Cretaceous Period.  Found in the region of Navarra, Spain.  Thanks to Dave at Views of the Mahantango for this fossil.  UPDATE: Whoops! The genus name was originally spelled incorrectly and it now fixed.

Melonites multipora Sea Urchin

The Melonites multipora sea urchin fossil found in St. Louis, Missouri.  The creature existed in the Mississippian Period.  It was on display at the Smithsonian Museum of Natural History (August 2010).  The description said it was once the size of grapefruit before getting flattened during fossilization.

Tylocidaris clavigera

Tylocidaris clavigera (Mantell, 1822) cast of a sea urchin fossil found in England.  The creature existed in the Cretaceous Period.  Cast on display at the Smithsonian National Museum of Natural History.

Stereocidaris hemigranosus

Stereocidaris hemigranosus sea urchin fossil on display at the Smithsonian National Museum of Natural History in Washington, DC.  The fossil is from Texas and existed in the Cretaceous Period.

Eocene Echinoderm Fossil

Echinoderm fossil that existed in the Eocene Epoch of the Palaeogene Period.  It was found in Monroeville, Alabama (Gosport Sand?).  My research shows two sand dollar fossils being found in Alabama: Periarchus lyelli and Protoscutella mississippiensis. This specimen does not have much detail on the top of the fossil.

Alabama Echinoderm Fossils

Echinoderm fossil that existed in the Eocene Epoch of the Palaeogene Period.  It was found in Monroeville, Alabama (Gosport Sand?).  My research shows two sand dollar fossils being found in Alabama: Periarchus lyelli and Protoscutella mississippiensis. The descriptions were difficult to decode and the images I found need to have higher resolution and contrast.

Thanks to Herb and Pam for the specimen.

Egyptian Sea Urchin Fossils

Echinoderm fossils found in Egypt and now on display at the Natural History Museum in Paris, France. This first fossil image is of the Lutetiaster cavernosus from the Lower Eocene Period.

This second picture is of the Lower Eocene Period sea urchin, Megaoneustes grandis found in Egypt.

Hemiaster Sea Urchin Fossil

This fossil is a Echinoderm (sea urchin) called Hemiaster sp. It existed in the Cretaceous Period about 100,000,000 years ago. The fossil was found in Tarrant County, Texas.

Thanks to Herb for the fossil. Apparently they are just found in this condition with no air abrasive cleaning needed.
