DescriptionZoophycos trace fossil (Mississippian; Clack Mountain Road-Route 519 intersection outcrop, south of Morehead, Kentucky, USA) 2 (30786870927).jpg |
Zoophycos trace fossil in the Mississippian of Kentucky, USA. Trace fossils are any indirect evidence of ancient life. They refer to features in rocks that do not represent parts of the body of a once-living organism. Traces include footprints, tracks, trails, burrows, borings, and bitemarks. Body fossils provide information about the morphology of ancient organisms, while trace fossils provide information about the behavior of ancient life forms. Interpreting trace fossils and determination of the identity of a trace maker can be straightforward (for example, a dinosaur footprint represents walking behavior) or not. Sediments that have trace fossils are said to be bioturbated. Burrowed textures in sedimentary rocks are referred to as bioturbation. Trace fossils have scientific names assigned to them, in the same style & manner as living organisms or body fossils. The curving grooves in this rock sample are part of a trace fossil called Zoophycos, a distinctive feeding trace with an overall spiral morphology. Stratigraphy: float, possibly derived from the Cowbell Member of the Borden Formation Locality: roadcut next to the Clack Mountain Road-Route 519 intersection, south of the town of Morehead, southern Rowan County, Kentucky, USA (vicinity of 38° 07’ 39.32” North latitude, 83° 24’ 47.62” West longitude) |
