A new paravian dinosaur from the Late Jurassic of North America supports a late acquisition of avian flight
Abstract: Paravians are an important radiation of winged coelurosaurs more closely related to birds than to Oviraptor, that include dromaeosaurids, troodontids, unenlagiines, halszkaraptorines, and archaeopterygids in addition to derived avialans.
New Material from the Type Specimen of Megalneusaurus Rex (Reptilia: Sauropterygia) from the Jurassic Sundance Formation, Wyoming
Abstract: In 2008, an articulated distal forelimb of the type specimen of the large pliosauromorph Megalneusaurus rex (UW 4602) was discovered adjacent to the original excavation pit from which two hindlimbs had been collected in 1895.
Rediscovery of Wilber Knight’s Megalneusaurus Rex Site: New Material From An Old Pit
Abstract: We report the rediscovery of Wilbur Knight’s 1895 excavation site of the large Jurassic (Oxfordian) pliosaur Megalneusaurus rex from the Sundance Formation.
Taphonomic Analysis of a Dinosaur Feeding Site Using Geographic Information Systems (GIS), Morrison Formation, Southern BigHorn Basin, Wyoming USA
Abstract: While excavating a new quarry on the Warm Springs Ranch near Thermopolis, Wyoming, in 1995, workers at the Wyoming Dinosaur Center discovered dozens of shed theropod teeth and scattered sauropod bones above a heavily trampled carbonate mudstone.
The Occurance of Vertebrate and Invertebrate Fossils In A Sequence Stratigraphic Context: The Jurassic Sundance Formation, BigHorn Basin, Wyoming, USA
Abstract: The Middle Jurassic Sundance Formation of the western United States is an ideal setting to contrast sequence stratigraphic controls on vertebrate and invertebrate fossils because of its diverse and abundant fauna (Massare et al. 2014).
The Tenth Skeletal Specimen of Archaeopteryx
Abstract: Here we describe the tenth skeleton, which is the most complete and best-preserved archaeopterygid specimen to date. The almost complete skeleton is preserved on a single slab of pure limestone (Figs 1–3), and comes from an unknown locality and horizon of the Solnhofen area; its exact collection history is unknown to us.
