Wilkingia

In: Limestone, Mid-Hill Shale

This specimen is probably Wilkingia. But it could also be Phestia. I compared photos from a quick web search of each and I found examples of Wilkingia to be far more comparable. Wilkingia lived from the Carboniferous until the Permian periods of time. This particular specimen is from eroded matrix,Read More →

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. Maybe Pseudorthoceras,Read More →

Pecopteris

Original Catalog No. 2019-04-LS-000 Identification as Pecopteris is very likely. This comes from a newly found shale landslide. The piece had fallen out of the hill and was lying on the ground. The rock is very fragile. The colors shown are rarer in this area, more commonly being a greyRead More →

A solitary type of coral found commonly in the local limestone/marine layer. I have been told the two examples below are perhaps of two different species. The first piece is assumed to be Stereostylus. The second piece that is split down the middle was thought to perhaps be Lophophyllidium. ThatRead More →

A few layers of rock contain several concretions. We called these dinosaur eggs when we were younger, not knowing exactly what they were. We have come to find that these are simply hard, compact masses of matter. These settle within the muds and sands that make the local rocks. SomeRead More →

This specimen started out showing about 40-50% of itself within the Limestone matrix is was embedded in. I spent a good deal of time with the air scribe to free it. I am confident that it is Metacoceras, but I welcome other opinions. The row of raised nodes along theRead 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 →
