[2] In the summer of 1993, the holotype was presented to engineer Li Pai of the Hebei Provincial Office of Geology by a local farmer.

Li, along with Hou Linhai and Zhou Zhonghe, investigated the quarry from which it came, at the locality of the Dongtuyao brick factory, Northern Hebei Province, Linjituxiang Village.

They sought to compare the two specimens but learned from Dr. Hou in 2001 that the holotype Jibeinia had been lost, and existing casts were of too poor a quality to be decisive.

Thus they conclude that it will be impossible to rule out the possibility that the two are the same species, and that Vescornis is a junior synonym, unless the holotype of Jibeinia is rediscovered.

[1] The genus name comes from a Latinized form of the Jíbei region and the character Jí, which refers to one of the nine geographical divisions of ancient China.
