In 2003, researchers uncovered the remains of a theropod later referred to Dromaeosauridae. Dromaeosaurids are a clade of maniraptorans including well-known members such as&nbsp;<em>Velociraptor<\/em>&nbsp;and&nbsp;<em>Deinonychus<\/em>. The specimen displays a case of gigantism in paravians, a condition best documented in the dromaeosaurids&nbsp;<em>Achillobator<\/em>,&nbsp;<em>Austroraptor<\/em>,&nbsp;<em>Dakotaraptor<\/em>, and&nbsp;<em>Utahraptor<\/em>. In addition to certain morphological traits that differ from the dromaeosaurid norm, the smooth surface of the distal metatarsal II prevents referral of the &#8216;Naze Theropod&#8217; to dromaeosaurids (ginglymoidy of the distal surface of metatarsal II being considered an unambiguous synapomorphy of dromaeosaurids). The specimen also lacks a hypertrophied ungual of the second pedal digit, and is surprisingly small in comparison with those of equivalently sized dromaeosaurids such as&nbsp;<em>Utahraptor<\/em>. A heuristic search and Bayesian phylogenetic analysis were performed, providing the first phylogenetic analyses of this enigmatic theropod. Both analyses support a placement of this taxon within Paraves, a clade which includes Dromaeosauridae, Troodontidae, and Avialae (birds). Despite previous referral to &#8216;Deinonychosauria,&#8217; placement near or within any of the three major paravian subclades could not be retained. We also offer the first biostratigraphic placement of the Campanian-Maastrichtian, non-avian Antarctic dinosaurs and can, with confidence, determine the contemporaneous nature of the latest Cretaceous, dinosaur fauna in Antarctica.<\/p>\n\n\n\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Phylogeny of a new gigantic paravian (Theropoda; Coelurosauria; Maniraptora) from the Upper Cretaceous of James Ross Island, Antarctica Mentor:&nbsp;Dr. Judd A Case, Dept. of Biology at Eastern Washington University A description with phylogenetic analyses is provided for Imperobator antarcticus,&nbsp;gen. et sp. nov., an early Maastrichtian, basal paravian (Theropoda; Maniraptora) from the Naze Peninsula, James Ross &#8230; <a title=\"Ricardo Ely, McNair Scholar, and Judd A.
