A costumed version of Testudo represents the school at some sporting events both at home and away, including football and men's basketball. [16] [17] Students are put through a try-out process to "become" the mascot, the costume for which features an "M"-stamped turtle shell.
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.
Turtle carapaces and scutes from Red Sea turtles (Eretmochelys imbricata) were used in rings, bracelets, dishes, bowls, knife hilts, amulets, and combs. Carapaces from Kleinmann's tortoise were used as sounding boards for lutes, harps and mandolins. [16] Turtle shells were also used to make norvas, an instrument resembling a banjo. [26]
Pantestudines or Pan-Testudines is the proposed group of all reptiles more closely related to turtles than to any other living animal. It includes both modern turtles (crown group turtles, also known as Testudines) and all of their extinct relatives (also known as stem-turtles). [2] Pantestudines with a complete shell are placed in the clade ...
Odontochelys semitestacea (meaning "toothed turtle with a half-shell") is a Late Triassic relative of turtles [1] before Pappochelys was discovered and Eunotosaurus was redescribed, [2] Odontochelys was considered the oldest undisputed member of Pantestudines (i.e. a stem-turtle).
Cyamodontoidea is an extinct superfamily of placodont marine reptiles from the Triassic period. It is one of the two main groups of placodonts, the other being Placodontoidea. Cyamodontoids are distinguished from placodontoids by their large shells, formed from fused bony plates called osteoderms and superficially resembling the shells of ...
In contrast to their earth-bound relatives, tortoises, sea turtles do not have the ability to retract their heads into their shells. Their plastron, which is the bony plate making up the underside of a turtle or tortoise's shell, is comparably more reduced from other turtle species and is connected to the top part of the shell by ligaments without a hinge separating the pectoral and abdominal ...
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.
