A Silurian Dawsonoceras annulatum

Here is a Silurian period cephalopod classified as Dawsonoceras annulatum. 

It looks like a small part of its shell is left (the pinkish looking rock with the sine wave shapes in it). The rest of the fossil is just an imprint on a rock.

I found this specimen at KYANA fossil study and always like find this cephalopod fossil. More to come.

Bone Lip Sucker Fish Fossil

Here is another fossil I saw for sale at the Fossil Festival held at the Falls of the Ohio State Park in Clarksville, Indiana.

The box was labeled Bone Lip Sucker Fish from the Eocene (50 million years ago). It came from Jianghan City in Hubei, China.

Asaphiscus wheelerik Trilobite

Here is a Asaphiscus wheelerik trilobite I saw for sale at the Fossil Festival located at Falls of the Ohio State Park, Clarksville, Indiana.

It was priced at $35.

Petrified Wood

Here is another sample of a fossil KYANA was selling to raise money for the education fund during the Fossil Festival at the Falls of the Ohio State Park.

The festival allowed us to raise money and also provide very low cost teaching aides to teachers and helped children and adults learn more about fossils from the world around us.

This fossil is of petrified wood from somewhere in Utah.

Striatopora bellistriata Coral

Here is another picture I took with volunteering at the KYANA table during the Fossil Festival at the Falls of the Ohio State Park. It is a Striatopora bellistriata (Greene) classified as a tabulate coral from the Middle Devonian period. It was found at Cooper Lane Quarry in Clark County, Indiana.

Cystiphylloides Coral

Here is a fossil that was donated by a KYANA member for use during the Fossil Festival at the Falls of the Ohio state park to raise money for the education fund.

The fossil is Cystiphylloides sp., a Middle Devonian coral from Speed Quarry in Sellersburg, Indiana.

Cyclonema Gastropod (snail)

Here is a picture of a Cyclonema gastropod (snail) found in Trimble County, Kentucky during a KYANA (http://www.kyanageo.org/) field trip. It was found in an area where Ordovician fossils are found. It was found in May 2008.

Flexicalymene Trilobite Tail

Here is a possible Flexicalymene trilobite tail found in Trimble County, Kentucky. I think the rock I was looking in had Ordovician fossils in it.

There appears to be a piece of bryozoan in the rock as well.

Loxoplocus Gastropod (Snail)

Here is a Loxoplocus bowdeni gastropod from the Marble Hill Bed of the Rowland Member of the Drakes Formation (equivalent the Whitewater Formation in Indiana) in Trimble County, Kentucky, USA. It was found during a KYANA field trip in May 2008. It is about 4 cm in length. Also the genus is now known as Paupospira.

Fossil dates to the Ordovician Period Katian (Richmondian) Stage.

Falls of the Ohio State Park

The Falls of the Ohio Indiana State Park in Clarksville, Indiana is a GREAT place to visit if you are in the Louisville, Kentucky area. I think it costs maybe $3 for admission to the visitor center and they have some neat displays about natural history of the surrounding area.

A partial view of the fossil beds you can explore while there.

Trimerus delphinocephalus

Here are some more images of an Trimerus delphinocephalus (Green, 1832) trilobite shown at the last KYANA Geological Society (http://www.kyanageo.org/) meeting. A rare find to have one this large and be intact to this extent.  It was found in Clark County, Indiana in the Waldron Shale.

Trimerus Trilobite

At the KYANA held on this day, the president Mary Ann brought in a trilobite from the Sellersburg Quarry in Indiana. It looks to me to be an Trimerus delphinocephalus and I am guessing it is from the Silurian period. She was a little fuzzy on the details but thinks she found it in the parking lot and may have kicked it which broke off the section seen on the back right side in this first picture. A very nice find for this area!

More Magnified Bryozoan Pictures

Another bryozoan colony that has been magnified 10, 60, and 200 times. It is from the Ordovician period and has more of a stem than a spherical shape.

Bryozoan Colony Magnified

Here are three pictures of bryozoan colony magnified 10 , 60, and 200 times.

Probably collected at an Ordovician site. An Intel QX4 microscope was used to take these images.

Devonian Brachiopod from Clark County Indiana

This brachiopod was found in southern Clark County about 1 mile from Ohio River in Jeffersonville, Indiana in 2004. Washed out of yard after rain storm in subdivision off of Middle Road.

Devonian Brachiopod from Jeffersonville, Indiana

Here is a close up of a trilobite found in 2004 off Middle Road in Jeffersonville, Indiana.

Devonian Trilobite

Here is a trilobite tail piece embedded into a rock found in Jeffersonville, Indiana off Middle Road in 2004. It is probably a Phacops rana. Since they seem pretty common in that area.

Devonian Brachiopods

Found these in 2004 in my yard in a subdivision off Middle Road in Jeffersonville, Indiana.

They seemed to wash out of the ground after a hard rain shower.

Spiny Snail on the Floor

While waiting for volunteer orientation for IdeaFestival (www.ideafestival.com) at the Kentucky International Convention Center in Louisville, Kentucky, I was studying the images on the floor in the lobby. I took some pictures of the fossil images.

The images are wearing off floor but the artists were symbolizing the Falls of the Ohio. This picture is showing three snails. They also have images of trilobites, corals, sponges, and bryozoans.

Snail Platyceras dumosum

Here is the view of the rock shown in yesterday's entry but it is the bottom side.

It is neat the at fossil came through the bottom of the rock and it has spines underneath.

Again, this gastropod is from the Devonian Period Jeffersonville Limestone and appears to be Platyceras dumosum (Conrad, 1840).

Platyceras dumosum

Here is another picture of gastropod specimen posted earlier. It is from a different vantage point. My cousin found it in the Jeffersonville Limestone of Clark County, Indiana USA and has been slowly extracting it with a sand blaster.

It appears to be a Devonian Period snail (gastropod) called Platyceras dumosum (Conrad, 1840).

Brachiopod Paraspirifer acuminatus in Louisville Kentucky

Here is a brachiopod found at the Louisville Science Center.

It is a Devonian period brachiopod and was labeled Paraspirifer acuminatus.

Favosites epidermata Coral

Here is a Devonian coral found at a display in the Louisville Science Center located in Louisville, Kentucky. It is nice they have some of this coral because the Falls of the Ohio State Park located across the Ohio River has a lot of it.

The display identified this as Favosites (Emmonsia) epidermata.

Brachiopod Mucrospirifer mucronatus

Here is a brachiopod labeled Mucrospirifer mucronatus from the Devonian period.

This specimen can be found at the Louisville Science Center (www.louisvillescience.org).
