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 as
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.
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 of
This specimen of Cephalopod, CG-0004, belongs to the genus Metacoceras. Tainoceras was assumed for a short period of time, however 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 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 Lepidophylloides
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 clay
