Pseudorthoceras side view embedded in limestone

First described by G. H. Girty in 1912 as found in Oklahoma. This specimen was 3/4 exposed as attached to a rock. I am not positive, but I believe it would break into more than one piece if I attempted to remove it. I am always finding either Pseudorthoceras orRead More →

Metacoceras Fossil from Parks Township, Pennsylvania

First named by Alpheus Hyatt in 1883, Metacoceras is one of the two most common cephalopods I find in Parks Township. Pseudorthoceras is the other one, a narrow straight shelled genus. This specimen shows nice banding where the individual chambers are on the shell. The first photo shows the shellRead 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 →

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 →

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 →

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 →
