Yes, and the same thing seems to have happened with _Peishansaurus_,
another dinosaur named by Bohlin (1953) in the same publication as
_Heishansaurus_.  _Heishansaurus_ (without an "o") is based on
fragmentary material (apparently now lost).  Although originally
regarded as a pachycephalosaur by Bohlin, the most recent assessments
are that it is likely an indeterminate ankylosaur (Sullivan, 2006;
Arbour and Currie, 2015) or referable to _Pinacosaurus grangeri
(Arbour et al., 2009).
