Silutitan sinensis gen. et sp. nov. (holotype-IVPP V27874) in left lateral view. Squares separated by letters indicate relevant anatomical details. (A) Posteriormost cervical vertebrae, with the bifurcated pcdl (posterior centrodiapophyseal lamina) and podl (postzygodiapophyseal lamina). (B) Articulation of cervicals 14 and 15, showing the epiphophysis (epi) and the epipophyseal–prezygapophyseal lamina (eprl). (C) Cervical vertebrae 13 showing details of the eprl, podl and pcdl. (D) Cervical vertebrae 12 showing details of the podl, pcdl and the fl (flange). (E) Cervical vertebrae 12 and 13 with “pre-epipophysis” (prepi), visible eprl and markedly epipopophysis (epi). (F) Cervical vertebra 13 showing well developed lateral flange close to the centrum posterior end. (G) Cervical vertebra 11, with markedly “pre-epipopophysis” (prepi) together with developed epipophysis. Red arrows show the constricted anteroposteriorly diapophyses-tuberculum contact. Blue arrows highlight laminae bifurcations. Yellow arrow indicates associated pterosaur lower jaw. Scale bar: 50 cm.
