Decaschisma Silurian Period Blastoid Fossil

Today's post is a very rare find. A Silurian Period blastoid fossil found in the Waldron Shale. It was found in Clark County Indiana USA. The fossil appears to be a Decaschisma pentalobus. It is about 7 mm tall. Thanks to Kenny for the image and yes you were right you would one day find a blastoid in the Waldron Shale. :)

Endothyra Foraminifera Fossils Revisited


In 2010, I posted some images of this type of microfossils found in Spergen Hill, Indiana, USA. This place is a type locality where this particular species was found and named in the literature first. Since my cousin Kenny recently acquired a new Amscope microscope I asked him to image some of these fossils for this posting.

These images are of foraminifera fossils from the Salem Limestone of Washington County, Indiana, USA. These creatures are called Globoendothyra "Endothyra" baileyi and existed 360-325 million years ago (Mississippian Period).

A very good write up on this particular fossil can be found on the Fossil Forum site written by user dshamilla. http://www.thefossilforum.com/index.php?/topic/54262-revisiting-spergen-hill-indiana-and-some-of-its-mississippian-micro-fossils/

Thanks to Kenny for the images.

Aran Island Microscopic Sea Creature Remains

 Continuing with yesterday's posting about microscopic sea creature remains found near Killagoola, Aran Islands, Ireland. The first image is of an unidentified echinoid spine and the 2nd image is an unidentified yet colorful gastropod. Thanks to Kenny for the images. Neither specimen appears to be a fossil yet.

Foraminiferas from Ireland


I do not think these remains of microscopic creatures are fossils yet. Here are three images of some foraminifera found near the Plassey ship wreck, Killagoola, Aran Islands off coast of Galway, Ireland. They have a fields of view (FOV) ranging from 1-2 mm. Thanks to Kenny for these images.
Years ago, I traveled to the Aran Islands while visiting Ireland and it was a rough boat ride. Too bad at the time I was not aware of all the neat microscopic remains to found on the beaches.



Below is a map showing approximately where everything was found.

X-Ray of Trilobite Fossil


This trilobite is a Calymene sp. found in the Waldron Shale. The fossil was found in Bartholomew County, Indiana USA and dates to the Silurian Period. It was found years ago but it is small thus easy to x-ray. The x-ray did not reveal any thing new except the crack in the matrix that extends through the fossil.

2000th Posting + The Hidden Lophophore Fossil


I have made it to my 2000th posting and I thought I would write about something special. In the past, I have marked other milestone postings with reviews of favorite fossils or most visited pages. You can find links to those at the end of this post, if you are curious.


This post is about maybe a unique discovery that has not been documented yet. Recently, I was testing x-ray sensors and while one can x-ray keys, pens, paper clips or calibration targets while testing, I got a bit more creative. I started to x-ray small fossils in my test image batch. Almost all of the time they were solid with a consistent layer but every so often I would see some other hidden details.


While taking an x-ray of a Devonian brachiopod Productella spinulicosta (Hall, 1867, aka Spinulicosta spinulicosta), I discovered it had a tube like structure embedded in its fossil form. It appears to be some sort of lophophore (feeding tube). My research has not found other images of lophophores from this genus of brachiopod so maybe this is the first time it has been visually documented. In x-ray images the green arrow points to the lophophore, light blue arrows point to spines.

As for this blog, I thought I would eventually run out of material to post but I continue to visit museums and on rare occasions field collect. Also my cousin Kenny has a nicer microscope/camera system that is yielding amazing images of microfossils he has been collecting. So I seem to have a good source of material to write about in the near future. Thanks for reading.

Fossils Embedded in Column at Speed Art Museum


If you ever visit the Speed Art Museum in downtown Louisville next to the campus of the University of Louisville, check out the polished columns leading the Grand Staircase. The arrow in the image points to an area of the column with interesting fossils. It is next to the entrance to the Ancient art rooms.

The image above shows crinoid stem sections. The one shaped it a star pattern is particularly nice. The next image appears to be fenestrate bryozoan fossil. The polishing of the slab has made its details standout quite nicely.


On a future visit, I might ask the staff if they have any information about where rock columns were quarried at.

Also in the first picture you can see (in between column and statue) in the distance an Egyptian sarcophagus lid made of limestone. It has quite a few fossils embedded in it. Unfortunately, it is on loan from another museum and is not allowed to be photographed so I cannot make a specific post about it. :( So if you visit the museum check it out up close in its display case and see if you can find the fossils!

Productus wortheni Brachiopod Fossil with Spines!


Wow, another special image similar to a posting 2 days ago. The Mississippian Period brachiopod fossil Productus wortheni found in the Knobstone Formation of Clark County, Indiana, USA shown in image. The special item about this image is the spines preserved in the sandstone matrix. They are so delicate yet survived the fossilization process and here they are hundreds of millions a years later.

Kenny, thanks for the image of this very sweet find.

Productus wortheni Brachiopod Fossil


The Mississippian Period brachiopod fossils Productus wortheni found in the Knobstone Formation of Clark County, Indiana, USA. What is nice is the cast and its negative still in the matrix. Note the small divots in the negative marking where spines were.

Thanks for the image Kenny.

Syringothyrus Brachiopod Lophophore Fossil


Here is a fossil I do not think I have seen before. The Mississippian Period brachiopod Syringothyrus texta found in the Knobstone Formation of Clark County, Indiana, USA. What is special about this is the feeding tube (lophophore) is shown.

Nice find Kenny!

Fossils at the Speed Art Museum


I visited the Speed Art Museum in downtown Louisville next to the campus of the University of Louisville. The museum opened on January 15, 1927 as the J.B. Speed Memorial Museum. It features artworks by Rembrandt, Cezanne, Matisse, Picasso, and Rockwell. My visit I was interested in the Ancient Art area. After visiting the MET in New York City, I thought looking at Egyptian limestone might yield more fossil finds. This hunch proved right.


The museum as a limestone relief of Thoth, Egyptian god of wisdom, writing, magic, and the moon. This image was probably depicting a burial ceremony where Thoth is listing the vices and virtues of the deceased as they move to the afterlife. Near the back of the head in the stone is a dark area. This appears to me to be a cross-section of a brachiopod fossil. The inner part might be filled with calcite crystals.

The artwork is from the Late Period (about 1000 B.C.). The museum acquired the piece in the 1970s.
