Geological and Paleontological Information
Michelinoceras is a genus of extinct orthoconic nautiloid cephalopods, often preserved in marine sedimentary rocks. The Hungry Hollow Formation is a fossil-rich unit within the Devonian-aged Hamilton Group, and is internationally recognized for its exceptionally preserved marine fauna, including brachiopods, corals, trilobites, and cephalopods.
- Phylum: Mollusca
- Class: Cephalopoda
- Order: Orthocerida
- Family: Michelinoceratidae
- Superfamily: Orthocerataceae
- Geological Stage: Middle to Upper Devonian (specific member stratigraphy varies within the formation)
- Depositional Environment: Warm, shallow marine carbonate shelf; characterized by limestones and calcareous shales with high fossil content
- Morphological Features: Long, straight shell (orthocone) with multiple internal chambers (phragmocone) separated by septa; features a central or subcentral siphuncle for buoyancy regulation; surface may show growth lines or fine transverse ornamentation
- Notable: Fossils from the Arkona area have been key in refining Devonian biostratigraphy in North America. Cephalopods like Michelinoceras reflect a transitional evolutionary stage toward more complex coiled nautiloids and ammonoids.
