The local section, the Glenshaw Formation, is home to many different phylum or classes of Marine and Plant fossil fauna. This formation is late Pennsylvanian in age. Every class is not equally represented in each particular area. Rocks from one hillside may be diverse, whereas rocks from the opposite hillside may have only a few species. This varies widely throughout the formation as a whole, where some areas have no easily detectable fossils.
The visible fauna are mostly from two major kingdoms of life, Animalia and Plantae. There are likely examples of Fungi, and perhaps Protozoa and Bacteria, but I don’t posses the knowledge to find and identify these types. Animalia is grouped into two main types, vertebrates and invertebrates. This is surprisingly not something always written in scientific classification. However it is widely known which type belongs to which, with some small exceptions. For example, Petalodus belongs to the subphylum Vertebrata.
Classes or Phylum of life found locally
The following types of life by common name are available locally:
Horn corals are somewhat abundant in Brush Creek Limestone locally. The particular order is named Rugosa. Typically these are locked in limestone and can be difficult to remove cleanly.
These are quite beautiful finds when they show up. They are likely common, however I often find them broken up into pieces. The net-like matrix of openings were the living chambers of the animal. Each chamber holds between two to eight individuals. The number is known as each individual leaves two small rimmed pores in the front of each branch.
