Recent work has suggested that the presence of extraoral soft tissues (‘lips’), in the form of labial scales in theropod dinosaurs, could be inferred based on: anteroposteriorly distributed foramina ....

A three-dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previo...

Abstract. Pinacosaurus grangeri is among the best-known ankylosaurids from the Late Cretaceous of Asia, yet most of the available information is based on j
