|---|---|---|
| J. L. Carballido et al. 2012 | C. windhauseni gen. et sp. nov. is characterised by the following characters (* indicates unique autapomorphic characters): 1*-anterior dorsal centra with strong lateral constriction, resulting in a thin ventral keel; 2*-anterior dorsal vertebrae with long prezygapophyses, which in anterior view cover around 3/4 of the transverse processes; 3*-anterior dorsal vertebrae with two spinoprezygapophyseal laminae; 4*-anterior dorsal vertebrae with two spinodiapophyseal laminae, an anterior and a posterior one; 5*-anterior median lamina formed by three different laminae, the anterior and posterior spinoprezygapophyseal laminae and the anterior spinodiapophyseal; 6*-posterior dorsal centra with the centroprezygapophyseal lamina medially divided; 7*-posterior dorsal neural arches with three spinopostzygapophyseal laminae; 8*-double contact between the posterior spinodiapophyseal lamina and the lateral spinopostzygapophyseal lamina; 9-anterior caudal vertebrae with well-developed prezygodiapophyseal fossa; 10-caudal vertebrae with short transverse process; 11- robust humerus, with a robustness index of 0.3 (sensu Wilson and Upchurch 2003); 12-ischium with straight shaft; 13-shaft of the ischium forming a right angle with the acetabulum; 14-iliac peduncle without a constriction or neck. |
