An isolated, fully articulated hindlimb of a basal iguanodont from the
Spanish Las Hoyas Lagerstätte is described. It probably belonged to a
juvenile or subadult individual. Despite some slight differences,
anatomical features, as well as the late Barremian age of this
specimen, would suggest that it belongs to Mantellisaurus
atherfieldensis. The exquisite preservation of this specimen provides
information on the foot anatomy of basal iguanodonts. This is the
first report of a non-theropod dinosaur from Las Hoyas. From a
palaeoecological point of view, this discovery indicates that
potential prey of the carcharodontosaurian theropod Concavenator were
present at Las Hoyas, thus complementing our knowledge of the trophic
structure of this Early Cretaceous palaeocommunity.
