    In: PeerJ, 2020, vol. 8, p. e8493

    Allosaurus, from the Late Jurassic of North America and Europe, is a model taxon for Jurassic basal tetanuran theropod dinosaurs. It has achieved an almost iconic status due to its early discovery in the late, 19th century, and due to the abundance of material from the Morrison Formation of the western U.S.A., making Allosaurus one of the best-known theropod taxa. Despite this, various...

    Rauhut, Oliver W. M. ; Tischlinger, Helmut ; Foth, Christian

    In: eLife, 2019, vol. 8, p. e43789

    The Late Jurassic ‘Solnhofen Limestones’ are famous for their exceptionally preserved fossils, including the urvogel Archaeopteryx, which has played a pivotal role in the discussion of bird origins. Here we describe a new, non-archaeopterygid avialan from the Lower Tithonian Mörnsheim Formation of the Solnhofen Archipelago, Alcmonavis poeschli gen. et sp. nov. Represented by a right...

    Re-evaluation of the Haarlem Archaeopteryx and the radiation of maniraptoran theropod dinosaurs

    Foth, Christian ; Rauhut, Oliver W. M.

    In: BMC Evolutionary Biology, 2017, vol. 17, p. 236

    Archaeopteryx is an iconic fossil that has long been pivotal for our understanding of the origin of birds. Remains of this important taxon have only been found in the Late Jurassic lithographic limestones of Bavaria, Germany. Twelve skeletal specimens are reported so far. Archaeopteryx was long the only pre-Cretaceous paravian theropod known, but recent discoveries from the Tiaojishan...
