Resumen

The Andrés fossil record reveals a rich and diverse Late Jurassic vertebrate
fauna from the Lusitanian Basin. The most abundant are dinosaur
remains, represented by sauropods, ornithopods, and theropods. Here, we
present a taxonomic study of six isolated theropod teeth from this locality,
based on morphometric and phylogenetic methods. Five of these teeth are
assigned to small dromaeosaurids, and a small tooth crown is interpreted as
belonging to a juvenile Allosaurus.
