There is no evidence to support a size difference between sexes. At one time measurements of existing specimens indicated that there were two size types, and these were thought to perhaps represent different sexes. However, measurements from newer speciemens seem to have ruled out the possibility of the size types, and thusly any difference between genders (aside from the medullary bone which would have no impact on the animal in the mod) is unknown.
