Summary
[edit]DescriptionJuvenile Stegosaurus dinosaur footprint (Morrison Formation, Upper Jurassic; Dinosaur Ridge, west of Denver, north-central Colorado, USA) (15541291642).jpg |
Juvenile Stegosaurus dinosaur footprint, preserved as a concave epirelief in fluvial sandstone from the Jurassic of Colorado (public display, Morrison Natural History Museum, Morrison, Colorado, USA) (footprint is about 5 cm across). Stratigraphy: Morrison Formation, Upper Jurassic Locality: Dinosaur Ridge, west of Denver, north-central Colorado, 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. |
