There is a category of type specimen called "plastotype": a cast of the original holotype. For example, the holotype of Poekilopleuron was destroyed, but its plastotype remains as the new type specimen.
Same for _Kakuru kujani_ - although in this case the holotype tibia was not so much "destroyed" as "disappeared". Its disappearance may have something to do with the fact that the fossil was opalized.
