The local limestone stratigraphy gives paleontologists ample opportunity to find specimens from the class Cephalopoda. These layers are all exposed as part of the Glenshaw formation, the dominant formation within Parks Township. The specimens below represent a few of the many different cephalopods genus that are available.
Found Cephalopod Genus from the Glenshaw Formation
The following are single examples of each genus. I originally had the large cephalopod identified as Brachycycloceras, but after some research I am changing my identification back to Solenochilus. During a visit to the Carnegie Museum, there was only one specimen, CM 29726 available to review, and it was re-cataloged during my visit. I brought along my specimen, specimen CG-0025. After review and identification of it’s genus, we tracked down an example they had, which came from nearby Sewickley, PA.
After showing photos of the specimen to Royal Mapes, his opinion was different. He said that CM 29726 was defiantly not a Brachycycloceras and closer aligned with Solenochilus. The Carnegie Museum specimen comes from the Pine Creek Limestone. The way the rock appeared was very similar to Pine Creek limestone in Ford City where I have found a number of gastropods and a few cephalopod fragments.
