The generic name is derived from the nearby town of Jaklapalli, where the holotype was discovered. The species name was derived from the talus bone’s obvious asymmetry.

The generic name Janenschia honours Werner Janensch, a prominent German scholar who has led the largest palaeontological digs in history, specifically in Tendaguru, since 1909.

Jaxartosaurus

Jaxartosaurus is a kind of hadrosaurid from the Lambeosaurinae group that lived in present-day Kazakhstan during the late Cretaceous period. Riabinin described it in 1939. The name Jaxartosaurus is derived from the Greek sauros and the old name of the river Syr Daria (Jaxartes) (“reptile”, “lizard”).

Jeholosaurus


Jeholosaurus is an Early Cretaceous Period member of the Neornithischia group. It is likely to have been a tiny herbivorous ornithopod.

Jeholosaurus means “Jehol lizard.” Jehol is the traditional name for western Liaoning and northern Hebei (incidentally, it is also the name of a group of geological formations consisting of the Yixian and Jiufotang). The species name (shangyuanensis) also relates to the discovery’s site – the Shangyuan region.

Jeyawati


Jeyawati is a monotypic ornithopod genus in the Hadrosauroidea family. Its holotype was discovered in Late Cretaceous sediments in the state of New Mexico. It is made up of both skull and extracranial skeletal components. According to research, these fossils belonged to a single person.

The generic name Jeyawati is derived from the Zuni language, which is spoken by a tribe of North American Indians in New Mexico, and means “polished lips.” Ruga (wrinkled) and oculus (eye) are two Latin words that allude to the lateral surface surrounding the ornithopod’s ornithopods.
