Ichnofossils, also known as trace fossils, are geological records of biological activity rather than preserved body parts, encompassing structures such as burrows, tracks, trails, borings, and coprolites. They provide direct evidence of organism behavior, ethology, and organism–substrate interactions, often where body fossils are absent. Ichnofossil analysis underpins ichnology and is used to interpret paleoenvironmental conditions, substrate consistency, energy regimes, and bioturbation intensity. Because ichnofossils are typically preserved in situ, they are critical for refining depositional models, sequence stratigraphy, and basin analysis, and for constraining the distribution, locomotion, and trophic strategies of ancient benthic and nektonic communities.
An international team has found that equations to determine the speed of a moving dinosaur based on prints in trackways may be inaccurate. In their study published in the journal Biology Letters, the group urged test guineafowl ...
