Qiu et al., 2019 shing-TYEN-oh-SAWR-us

Named after Xingtian, a Chinese deity who continued to fight after being decapitated, referencing the skull-less holotype specimen, plus Greek sauros ('lizard')

125.8–121.4 million years ago Barremian, Early Cretaceous
Early Cretaceous stages

Xingtianosaurus is an extinct genus of oviraptorosaurian theropod dinosaur that lived in what is now China during the Early Cretaceous. The type and only species, X. ganqi, was named and described in 2019. It was placed in the Caudipteridae, alongside Caudipteryx and Similicaudipteryx.

Diagnosis

  1. Small pleurocoel close to the dorsal edge of the lateral surface of the dorsal vertebral centrum
  2. Humerus longer than the scapula
  3. Proportionally long ulna subequal in length to the humerus
  4. Relatively small radiale angle of approximately 39° compared to >48° in other oviraptorosaurs
  5. Extremely short metacarpal I less than 40% the length of metacarpal II
  6. Small ligament pits on the manual phalanges, dorsally located

Species
