A new look at <i>Crocodylopodus meijidei</i>: implications for crocodylomorph locomotion

A review of the type material crocodylomorph ichnotaxon Crocodylopodus meijidei Fuentes Vidarte and Meijide Calvo, 2001 from Berriasian Spain is carried out. The allows a better characterization this provides interesting new data on candidate trackmakers especially their locomotion. Three different size classes possibly related to ontogenetic states or sexual dimorphism same small- medium-sized trackmaker are distinguished. Morphological differences within sample such as digital impression lengths might be consequence in allometric growth, assuming similarities with extant crocodylians. Other variation morphological quality mode preservation across sample. Some trackway features (intermediate-gauge trackways high pace angulation, absence tail, belly drag marks) indicate trackmakers, presumed neosuchian crocodylomorphs, were walking ‘high-walk’ semi-erect posture at moderate speed. may have walked more erect limb center mass located anteriorly than occurs species, albeit not quadrupedal animals mammals other extinct archosaurs including ichnotaxa (e.g., Batrachopus).
