Face to face with Tyrannosaurus

| New research reveals that the face in tyrannosaurs was covered by an extensive mask of large, flat scales, and regions of armor-like skin on the snout, jaws, and ornamental horns. The large horn behind the eye was covered by the same material that makes human fingernails. The small bumps on the flat scales are Integumentary Sensory Organs (ISOs), as are seen in crocodiles, that provide extreme tactile sensitivity. |
