Composita was a genus of brachiopod from the Late Devonian up until the Late Permian. There are a few pieces of the original shell attached to the fossilized inside. This form of fossil is also known as a Steinkern. This species is very common in the local marine zones. ThisRead More →

Crinoid Stem

By far the largest Crinoid Stem I’ve found so far. This was in a thin triangle of Limestone and was easy to get out. I count six columns stuck together here. Crinoids are very common locally, however larger ones are more rare. I still would like to find a CrownRead More →

A sea pen from the genus Pteronites. I am still looking for more information about Pteronites in general. There is also a second example available. Kingdom: Animalia Phylum: Cnidaria Class: Anthozoa Order: Pennatulacea More about Pteronites Fossilworks – listing on PteronitesRead More →


Pseudorthoceras was first described by G. H. Girty in 1912. It was part of a paper describing new species of Pennsylvanian fossils from the Wewoka Formation of Oklahoma. The species appeared 376 million years ago and disappeared during the Permian–Triassic extinction event, 252 million years ago. This extinction, known asRead More →

Huge slabs of weathered shale and slate run down the local stream nearby. Lifting pieces up can introduce you to a large number of different fern fossils. There are bits of Lepidophylloides and pieces of Lepidodendron bark. The ferns could be Neuropteris or Pecopteris, and I am leaning towards Pecopteris.Read More →

The shell is probably Schizodus I am told. The impression of the Crinoid is well defined. In my opinion this specimen worth keeping. Schizodus was first described by W. King in 1844. It’s interesting to wonder if this impression was left during the burial process, or was the result ofRead More →

Specimen Front

This specimen of Cephalopod, CG-0004, belongs to the genus Metacoceras. I first assumed Tainoceras, yet, that genus does not occur in the Brush Creek Limestone. A good deal of time was spent using an air scribe to take the piece from the first photo in the gallery to get toRead More →

The clam Palaeoneilo is easy to spot on this specimen of shale. But, what I assumed was Lepidophylloides under the Microscope really sold me on adding this to my formal collection. Is it a leaf or a spine? However, after some further discussion with more seasoned fossil experts, the LepidophylloidesRead More →

Meekospira peracuta is a high-spired gastropod. This specimen was found next to a concretion in shale. The large outer rim of the concretion is visible as a curved piece on the rock. The tip of the snail was more prominent when first pulled out, and attempted removal of the clayRead More →
