 All four limbs are missing, with the exception of 9 small Phalanges (finger bones) and a small number of limb bones found close by which may belong to the animal in question.The specimen is believed to be an adult, due to the fusion of certain bones (it is generally assumed—not necessarily strictly correctly so—that other animals' skulls, much as humans', consist of dissociated bones interconnected by cartilage fontanelles that do not entirely close until full maturity).It is also believed to have been substantially smaller than its close relative, "D. osborni", as some juvenile specimens of "D. osborni" are larger than the adult specimen of "D. herschelensis".
