What Order defines Xenotarsosaurus as possessing a "lizard-hipped" pelvis?
Answer
Saurischia
The classification Order Saurischia is characterized by the structure of the pelvis, which is described as the 'lizard-hipped' arrangement. This configuration is considered more ancestral compared to the pelvic structure found in modern reptiles. Unlike the Ornithischians, whose pubis bone generally points forward, the Saurischian hip structure retained an older configuration. Although this Order includes diverse forms like long-necked sauropods, *Xenotarsosaurus* is specifically situated within the predatory subgroup of this Order.
