The internal mold preserved the detail of the shell ridges well, but does not show the dentition which would be a powerful tool for proper identification. This internal mold only shows one of the valves so it is hard to determine if the valves were equilateral or not. This bivalve is representative of bivalves in this period because at this point bivalves hadn't flourished and are primarily rare to common in abundance. Trilobites in the Waynesville formation were represented by fragments, and were fairly abundant. Trilobite morphology is distinguished by their three lobes.
Trilobites have two pleural lobes and an axial lobe in the center.
All of the trilobites we found were represented by fragments that had been scattered in the assemblages. The representative fragments we found demonstrate primarily phacopid trilobites. The fragments were all unaltered hard parts and easy to identify with their rusted earth brown color still intact. The abundance's were actually extremely abundant fragments, they were just all over the place, but it would have been nice to find a nice mold of a whole trilobite, they were found in other formations of the Ordovician. Overall we found abundant fragments of the Order Phacopida in the Waynesville formation.
