More on 300 pterosaur tracks discovered at Praia da Peralta in Portugal in 2010; now have been studied in a  thesis (Simon Kongshøj Callesen: "New Pterosaur Tracks (Pteraichnidae) from the Late Jurassic of Praia da Peralta, Portugal"); tracks show quadrupedal gait and are bigger than any Jurassic  pterosaurs known from fossil bones; with audio from Octávio Mateus (in Portuguese)
