A dinosaur track was recently discovered at Buarcos (Figueira da Foz, Portugal). The stratigraphic level is in the upper part of Boa Viagem Sandstone Formation, and specimen first evidence for presence middle Kimmeridgian dinosaurs Cabo Mondego area. This reveals a medium size theropod estimated with one meter height to hip. Moderate dinoturbation indicate more than that time. finding suggests area may have relevant ichnological fossil record, highlighting importance further works this formation. It's also good indicator remains which are poorly known time interval. Based on currently distribution record Upper Jurassic Lusitanian Basin, trackmaker could been either Ceratosaurus, Lourinhanosaurus or Allosaurus. paleoenvironment interpreted as deltaic alluvial plain, small migrating channels flooding areas. footprint has didactic aesthetic features which, display museum, contribute enhance cultural educational activities. context discovery allows address issues geological heritage.
