- Pangolin scales are made of keratin, the same material found in a rhino's horn12. The scales are reportedly so tough that even a lion can't bite through them12. The crossed lamellar arrangement of the keratin fibers in the pangolin scales enhances the fracture toughness, making it hard for cracks to propagate after an impact34. The scales have a Young's modulus of ~1 GPa and a tensile strength of 60-100 MPa3.
