N2 - We describe the first American stegosaur track of the ichnospecies Deltapodus brodricki, collected in the Upper Jurassic Morrison Formation of San Juan County, southeastern Utah, United States. The track is preserved as a natural cast on the underside of a slab of fluvial sandstone and consists of a well-preserved pes track and the eroded remains of a manus track. Previously, Deltapodus was known only from the Middle Jurassic Yorkshire coast of England and the Upper Jurassic of Portugal and Spain. The new discovery thus substantially extends the geographic record of this ichnospecies and highlights the similarities between the Late Jurassic dinosaur faunas of North America and those of Western Europe.
