Update: Mooreoceras is no longer considered a valid genus. Kröger and Mapes (2005) compared more than 1,000 specimens and found that its type species, M. normale, cannot be separated from Pseudorthoceras knoxense. Specimens I once called Mooreoceras are now catalogued as P. knoxense. More on the Pseudorthoceras page. Going byRead More →
This brachiopod is beautifully centered in what is likely a concretion circle. The specimen was found in the high-hill shale. This layer contains a shale that I call mud stone. It comes out in larger pieces than thinner shale. The rock still splits rather easily, and it contains many concretions.Read More →
Antiquatonia portlockiana was first described by Norwood and Pratten in 1855. The genus Antiquatonia includes eight distinct species. It has a surprisingly short age range of about 20 million years. The species has yet to be found outside of the Carboniferous Period. When I first found this brachiopod, I wasn’tRead More →

The specimen passes through the rock, showing itself on the other side. A Crinoid stem impression can be seen on the opposite side. TheRead More →
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 →
