Over the course of their evolution, dinoceratans underwent a great increase in body size, from a weight of  in the earliest species to a weight of up to  in the largest species, co-inciding with the development of fully graviportal limbs with a digitigrade posture.
Over time, dinoceratans grew significantly larger, with weights increasing from an initial value to a maximum of , corresponding to the development of strong, graviportal limbs and a digitigrade walking style.
