Furileusauria ("stiff back lizards") is an extinct clade of derived abelisaurid dinosaurs only known from South American fossil remains.[1] They represent some of the largest members of the Abelisauridae, with an average length of Шаблон:Convert.[2] The clade is defined as the most inclusive clade containing Carnotaurus sastrei but not Ilokelesia aguadagrandensis, Skorpiovenator bustingorryi, or Majungasaurus crenatissimus.[1]

Classification

Distinguishing traits

Furileusauria is distinguished by several traits exclusive to the members of this clade. These are:[1]

  • the presence of a tip in the middle area of the posterior surface of the ventral process of the postorbital
  • the presence of a knob followed by a deep notch in the postorbital-squamosal contact
  • the absence of fenestra between the frontal, postorbital and lacrimal
  • an anterior projection of the distal end of the cervical epiphophyses
  • the posterior margin of the postzygapophyses at level with the intervertebral articulation in dorsal vertebrae
  • a crescent-shaped morphology of the distal tip of the transverse processes in anterior and middle caudal vertebrae
  • the transverse processes of anterior caudal vertebrae distally expanded and only anteriorly projected
  • a convex external margin of the transverse processes in anterior caudal vertebrae
  • cnemial crest of the tibia with a downturned process

Phylogeny

In the description of the abelisaurid Llukalkan, the authors performed a phylogenetic analysis to test the affinities of the new taxon. The simplified strict consensus tree of the analysis is shown below.[3] Шаблон:Clade
