Phaedrolosaurus

Phaedrolosaurus
Phaedrolosaurus is a genus of theropod dinosaur, based on a single toothpossibly from the Valanginian-Albian-age Lower Cretaceous Lianmugin Formationof Wuerho, Xinjiang, China.

The tooth, IVPP V 4024-1, was in 1973 described and named by Dong Zhiming as a new genus and species. The type species is Phaedrolosaurus ilikensis. The generic name is derived from the Greek φαιδρός, phaidros, "elated", referring to the agility of the animal. The specific name refers to the Ilike Formation. Dong stated the thirty-one millimetre long tooth was like those of Deinonychus, albeit thicker, shorter, and more solid. He regarded the new genus as a possible dromaeosaurid.[1]
