Dong Zhiming
A nearly complete skeleton of a theropod new to science was discovered by Dong Zhiming in 1981, during stratigraphic exploration for the benefit of the oil industry. The fossil was not unearthed until 1984. In 1987, before description in the scientific literature, it was referred to in the press as "Jiangjunmiaosaurus", an invalid "nomen nudum". In 1992 it was mentioned by Dong Zhiming as "Monolophosaurus jiangjunmiaoi", and in 1993 by Wayne Grady as "Monolophosaurus dongi". These latter names also lacked a description and therefore were "nomina nuda" as well.
