A turtle shell is a bio-composite consisting of a keratin-coated dorsal shell, or carapace, and a flat interior made of cancellous bone sandwiched between thin layers of cortical bone. The flat, bony configuration allows for significant weight reduction, thereby resulting in higher stiffness, strength, and toughness-to-weight ratios.
The turtle shell is a shield for the ventral and dorsal parts of turtles (the order Testudines), completely enclosing all the vital organs of the turtle and in some cases even the head. [1] It is constructed of modified bony elements such as the ribs, parts of the pelvis and other bones found in most reptiles.

Scutes on an alligator foot. A scute (/ s k j uː t / ⓘ) or scutum (Latin: scutum; plural: scuta "shield") is a bony external plate or scale overlaid with horn, as on the shell of a turtle, the skin of crocodilians, and the feet of birds.
Fictional metal, used by the residents of Asgard. Has the unique properties of being both highly durable and able to hold enchantments. It has been noted that only a god can safely apply permanent enchantments. Uru's durability makes it nigh-impossible to work with, requiring either the heart of a star or an enchanted forge.
The shells of cyamodontoids differ from those of turtles in several ways. Turtle shells are fused to their skeletons in several regions, including the vertebrae, ribs, gastralia (belly ribs), and pectoral girdles, but cyamodontoid shells overlie skeletal bones without any fusion. Turtle shells are also composed of two layers of osteoderms ...
Cryptodira is commonly called the "Hidden-Neck Turtles" or the "Inside-Neck Turtles". Cryptodira differ from Pleurodira (side-necked turtles) in that they lower their necks and pull the heads straight back into the shells, instead of folding their necks sideways along the body under the shells' marginals.
The tinbe can be made of various materials but is commonly found in vine, cane, metal, or turtle shell. The shield size is generally about 45 cm long and 38 cm wide. The shield size is generally about 45 cm long and 38 cm wide.
