© National Geographic Society Painting by Charles R.Knight Long Before the Pyramids Were Built, Mighty Arsinoitherium Fought Prehistoric Hyaenodons inEgypt The beast is named for the Egyptian Queen Arsinoe because its bones were discovered near the ruins of herpalace. Although the animal resembled arhinoc eros, the two large horns on the nose were not true horns. They were bony growths from the skull, and enabled the animal toward off the attacks ofHyaenodons (long toothed hyenalike creatures). These savage but slow marauders also existed in North America.
