It is difficult to find specimens of paleozoic cephalopod genus Domatoceras in local rocks. They can be found, but boththe genera Metacoceras and Pseudorthoceras dominate the cephalopod fauna. They are large cephalopods with a narrow venter. The younger whorls are only slightly or not impressed into the umbilical walls. Big
The extinct cephalopod Metacoceras clinocostatum is a species commonly found in Brush Creek limestone. Compared to other examples of the genus Metacoceras, it is very small in size. I was apprehensive about identifying these. In the past, I believed they were the inner whorls of larger specimens. However, these are
This specimen of Solenochilus was an interesting find in softened Brush Creek limestone material. The limestone can often be bisected as discovered in the ground. This is likely from stress fracturing. In between the fractures, I have mostly found clay. But the margins on each boulder can be softened and
Without a doubt, the genus Metacoceras is one of the two most common cephalopod genera found locally. This particular specimen preserves inner chambers. It did split in half while I was recovering it, but to my surprise, everything remained intact. Individual septal wall/suture lines can be seen on close inspection.
This Solenochilus, an extinct genus of paleozoic cephalopod, was found today (Late August 2020) after splitting a piece of float limestone half-buried in the mud at creek level upstream in Guffy Run. The rock was three inches thick and had a long rectangular shape. A heavy blow to the center
I have several specimens of Metacoceras piling up as I work on prepping them for display or storage. In prepping, I typically remove additional matrix, and I remove matrix covering details of the specimens. The white marks are a result of using an air-scribe to remove matrix. This tool strikes
