| 説明 | Fossil myriapod tracks in siltstone from the Permian of New Mexico, USA. (slab is ~11.9 centimeters across at its widest)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 tracks seen here come Permian terrestrial redbeds in New Mexico. They have been attributed to fossil centipedes.Classification: Animalia, Arthropoda, MyriapodaStratigraphy: Sangre de Cristo Formation, Lower PermianLocality: undisclosed locality referred to as the "El Pueblo site", Upper Pecos Valley, north-central New Mexico, USA |
