Brachycycloceras

I am currently updating this post. I received a more solid identification of Brachycycloceras after a visit to the Carnegie Museum. First described by Miller in 1933, the genus Brachycycloceras occurs from 326 million years ago up until the Permian extinction, 252 million years ago. This genus is relativity unknownRead More →

Seeing a 305 million year old prismatic surface on a piece of shell seems remarkable to me. After all that time, the shell surface still presents with a shimmer that captures and refracts light in several different directions. The views below show edge details and a close up of theRead More →

This specimen of Pseudorthoceras was exposed on the outside of a large piece of limestone in a local stream. It was several feet below the local layer, and likely fell into the stream a long time ago. A few swings of a sledge hammer and the 4 foot long stoneRead More →

Crinoid stems in Parks Township are typically discs. Rarely do you find them stacked 2 or 3 columns high. Crinoids are a living fossil, and several species are still alive today. While attempting to drop a huge piece of limestone from a steep hill, this 4cm long stem appeared. ItRead More →

I’ve found a large number of Metacoceras locally in Parks Township. Yet I haven’t found one quite like this specimen. Unique to this one, you can see the septal neck openings and the inner whorl channel. I also found a small piece of the next chamber, including the septal openingsRead More →

This combination piece came from hammering on already busted up Limestone. The Pseudorthoceras is long in comparison to most exposed specimens I find. Usually they are buried or the pieces that are exposed fall apart at the septal margins. The Metacoceras in this piece shows excellent septal suture lines andRead More →

Linoproductus was first described by Chao in 1927. It went extinct during the Permian / Triassic Extinction event 252 million years ago. More Reading About Linoproductus Online Taxon Page – FossilworksRead More →

First described in 1870 by Meek and Worthen, Solenocheilus is a genus of Cephalopod. The identification is most likely, as two experts have noted the wide square shape of the specimen. For a short time I considered Ephippioceras. However, this specimen is much too large to be Ephippioceras, which areRead More →

One of two large specimens found in the same rock. This rock was found as a large piece embedded about 3 feet up a hillside. After wrestling it to the ground, a large sledgehammer split it into three large pieces, so that I could transport them home. I started toRead More →

I often find bits of Metacoceras, a Coiled Cephalopod that existed between 314 million years ago until just before the Permian / Triassic Extinction event. I have been looking for complete specimens, but typically they are bisected on some sort of sediment plane within the limestone. Discovery In my localRead More →
