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.
The epidermal scutes of the alligator consists of oblong horny scales, arranged in transverse rows; the long axes of the scales are parallel to that of the body.On the tail, except along the mid-dorsal line, and on the ventral side of the trunk and head these scales are very regular in outline and arrangement; on the sides of the head and trunk and on the legs they are much smaller and less ...
The gular scute or gular projection on a turtle is the most anterior part of the plastron, the underside of the shell. Some tortoises have paired gular scutes, while others have a single undivided gular scute. The gular scutes may be referred to as a gular projection if they stick out like a trowel.
Scutes on a crocodile. Reptile skin is covered with scutes or scales which, along with many other characteristics, distinguish reptiles from animals of other classes. They are made of alpha and beta-keratin and are formed from the epidermis (contrary to fish, in which the scales are formed from the dermis).
The carapace is the dorsal (back) convex part of the shell structure of a turtle, consisting primarily of the animal's rib cage, dermal armor, and scutes. [ 3 ] [ 4 ] References
Arrangement of armor as suggested by Arbour and Mallon, 2017. A prominent feature of Ankylosaurus was its armor, consisting of knobs and plates of bone known as osteoderms, or scutes, embedded in the skin. These have not been found in articulation, so their exact placement on the body is unknown, though inferences can be made based on related ...
Chroniosuchus is known for its distinctive body armor of large bony plates, known as scutes, that cover its back and sides. These scutes varied among species providing clues of their evolution and classification among the Chroniosuchidae family.
The nuchal scute is located at the base of the head. [21] The carapace connects to the plastron by three pairs of inframarginal scutes forming the bridge of the shell. [ 21 ] The plastron features paired gular , humeral, pectoral, abdominal, femoral, and anal scutes. [ 8 ]
