[edit]Theropod research
[edit]- Piñuela et al. (2025) report the discovery of a theropod footprint preserved with a detached sandstone undertrack from the Upper Jurassic Lastres Formation (Spain), providing evidence of foot movement through the sediment and evidence of changes of footprint morphology at different levels of sediment depth, with some of the successive footprint outlines showing similarities to footprints of members of different dinosaur groups; the authors also reevaluate the type series of the ichnotaxon Iguanodontipus, and argue that some of the studied footprints might have been produced by a theropod.[5]
