- Scutes are similar to scales and serve the same function. Unlike the scales of lizards and snakes, which are formed from the epidermis, scutes are formed in the lower vascular layer of the skin and the epidermal element is only the top surface. Forming in the living dermis, the scutes produce a horny outer layer that is superficially similar to that of scales. Scutes will usually not overlap as snake scales. The outer keratin layer is shed piecemeal, and not in one continuous layer of skin as seen in snakes or lizards. The dermal base may contain bone and produce dermal armour. Scutes with a bony base are properly called osteoderms. Dermal scutes are also found in the feet of birds and tails of some mammals, and are believed to be the primitive form of dermal armor in reptiles. The term is also used to describe the heavy armor of the armadillo and the extinct Glyptodon, and is occasionally used as an alternative to scales in describing snakes or certain fishes, such as sturgeons, shad, herring, and menhaden.
This scute was found with the bones being sold and all came from the same animal. Bones from this Nodosaur are EXTREMELY RARE!!! This specimen measures approx. 2 7/8″ wide and comes in the 5.25″ x 6.25″ Riker Mount with Label as shown.
Denversaurus (“Denver lizard”) is a genus of herbivorous nodosaurid ankylosaurian dinosaur from the Late Cretaceous (late Maastrichtian) of western North America. Denversaurus, along withAnkylosaurus, was found in the lower part of the Hell Creek Formation. Tyrannosaurus andTriceratops were also found in this formation. But unlike these animals, both ankylosaurs were only in the lower part of the formation. This suggests that some ankylosaurs became extinct long before the end of the Cretaceous. It is not known what caused their extinction, but it seems to be at the same time a number of other dinosaurs became less abundant. Denversaurus is the latest known member of the Thyreophora. The Thyreophora (“shield bearers”, often known simply as “armored dinosaurs”) were a subgroup of the ornithischian dinosaurs. They were armored herbivorous dinosaurs, living from the early Jurassic until the end of the Cretaceous.
