Annnnnnnd, it is my tattoo. This one is Paradoxides gracliis from the same formation.

Just to give you an example of how big they can get, here is a size chart. Acadoparadoxides is the 2nd to the left.

#TrilobiteTuesday

Here is part of the body of quite a large trilobite known as Paradoxides spinosus. This specimen comes from the Middle Cambrian (Drumian) Jince Formation from the Czech Republic. Paradoxides is one of the largest trilobites known from the Cambrian period.

It's usually referred to as an anal tube. But because of the length it is called called the anal chimney. They can be as long as the arms of the crinoid.

Welcome back to #fossilfriday

Here is the crinoid Arthroacantha carpenteri with a Platycerid snail attached. These snails are Coprophagous which means they ate fecal matter. The snail would attached to the anal chimney of the crinoid and would feed on the waste.

Here is a beautifully enrolled Dolomitized Calymene celebra from the Silurian (Wenlock) Joliet Dolomite from Grafton, Illinois.

We are 2 for 2 with echinoderms for #fossilfriday!

Here is an absolutely beautiful regular sea urchin known as Desoricidaris pouyannei. This specimen comes from the Lower Cretaceous (Cenomanian) rocks of Taouz, Morocco. The preservation of the test (body) is absolutely stunning even after 100 mya!

Here are 3 beautiful Pentremites sp. Blastoids I collected from the Upper Mississippian (Lower Carboniferous, Serpukhovian) Lower Bangor Limestone in Russellville, Alabama.

Diane Acker and I at Late Ordovician Sequatchie Formation in Ringgold, Georgia. We are looking at the Ordovician-Silrurian boundary as well as collecting ichnofossils. @ichnologist.bsky.social has an excellent blog post about this. Check it out!

I wasn't expecting this! While out looking for fossils in the Chickamauga Group in Catoosa Co, Georgia, I found a trilobite cephalon fragment. Based on the insanely long genal spine and the hour glass shaped glabella, I believe it is a Cerauruid.

Evidence of this is found in the form of limestone and shale along the roads in Ringgold and Fort Oglethorpe. Within those rocks are evidence of the inhabitants of that sea. This includes brachiopods, ostacods, crinoids, bryozoans, and trilobites.

I am here in Catoosa County, Georgia next to the Chickamauga Group. This particular group of rocks dates back to the Middle-Late Ordovician period (~471-440 million years ago). During this time, NW Georgia was south of the equator and was covered in warm shallow epicontinental sea.

No, dinosaur controversy here, Here we have a beautiful sliced Halysitid (chain) coral from the Middle Devonian Callaway Limestone (Cedar Valley Group) of Columbia, Missouri.

I get to dress up at work today. I'll let you guess as to who I am going as. 🦖🦕

Here is a tiny partially enrolled Kaskia chesterensis trilobite from the Upper Mississippian (Lower Carboniferous, Serpukhovian) Lower Bangor Limestone Formation from Russellville, Alabama. Unfortunately the head isn't there.

Literally just got a cast of it last week! Prefect timing. I can't wait to see the finished piece.

Here is the holotype cast skull of Proceratosaurus bradleyi. It was found in the Middle Jurassic (Late Bathonian) Great Oolite Group (Forest Marble Formation) near Minchinhampton, a town in Gloucestershire, England.

Happy National Fossil Day! And happy Birthday to my mom. The one who encouraged me to stay curious and to never give up on my dreams. ❤️ ⚒️ 🪨 🎉

Here is the fresh water Dastilbe elongatus. This specimen comes from the Lower Cretaceous (Aptian-Albian) Santana Formation in Serra de Araipe, Brazil. The Santana Formation is well known for its exquisite preservation of pterosaurs fossils.

Circled are two cranidia from the trilobite Tricopelta breviceps. They are less common than trilobites like Flexicalymene and Isotelus within the Cincinnatian Series. This specimen comes from the Upper Ordovician (Richmondian) Liberty Formation in Franklin county, Indiana.

I had a fun time setting up at the Macon Museum of Arts and Sciences for their Fall and Fossil Fest. My friend and former science teacher Diane Akker helped as well. Over half a billion dollars was represented on 2 tables.

Ray Troll sent me this Paleo themed shirt with his art. So of course I had to model it. #Paleonerds

Been awhile since I've put anything up on my YouTube channel. The in the upcoming video we will going over Biomineralizaton and the organisms that use it to their advantage. Video drops tomorrow.

This upcoming Saturday (Oct 4th) The Macon Museum of Arts and Sciences will be having their Fall and Fossil Fest. It will be from 10AM-4PM. I and many others will have tables in the museum full of fossils. If you want to learn more about Georgia's prehistoric past, recommend attending this event.

Did someone order seafood on the menu? Here are the shells of the oyster Exogyra cancellata. These come from the Late Cretaceous (Late Campanian) Demopolis Formation in Tueplo, Mississippi. These oysters are so common that you fill your backseat with them.
