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 →
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 →
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 →
The shell is probably Schizodus. 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 compression of theRead More →
Not sure what this is. I feel like it is common. What was interesting is the original shell material and the fact that it was two shells stacked. The first assumption I’ve heard is that it is Linoproductus.Read More →
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 →
