The holotype, CV 209, was found in a layer of the Upper Shaximiao Formation, dating from the Oxfordian-Kimmeridgian. It consists of a rather complete skeleton that however lacks parts of the skull, lower jaws, tail and limbs. In 1977, it represented the most complete stegosaurian skeleton found in Asia. The paratype was specimen CV 210, a ...
Stegosaurus (/ ˌ s t ɛ ɡ ə ˈ s ɔːr ə s /; [2] lit. ' roof-lizard ') is a genus of herbivorous, four-legged, armored dinosaur from the Late Jurassic, characterized by the distinctive kite-shaped upright plates along their backs and spikes on their tails.
The spikes of Kentrosaurus are very elongated, with one specimen having a bone core length of 731 millimetres. [20] The plates have a thickened section in the middle, as if they were modified spines. [33] The spikes and plates were likely covered by horn. Aside from a few exceptions they were not found in close association with other skeletal ...
Thyreophora ("shield bearers", often known simply as "armored dinosaurs") is a group of armored ornithischian dinosaurs that lived from the Early Jurassic until the end of the Cretaceous.
One of the seventeen neck vertebrae, seen from the right upper side. Miragaia is based on holotype ML 433, a nearly complete anterior half of a skeleton with partial skull (the first cranial material for a European stegosaurid). [1] The remains were found after the construction of a road between the villages of Miragaia and Sobral. The rear ...
Galton and Carpenter considered Alcovasaurus a member of the Stegosauridae, not more closely related to Kentrosaurus than to Stegosaurus. [1] However, a 2017 phylogeny of stegosaurids by Thomas Raven and Susannah Maidment found that Alcovasaurus lacked the fusion between the trochanters of the femur seen in adult eurypodans (stegosaurians and ankylosaurians), which means that it cannot be ...
Hesperosaurus was a member of the Stegosauridae, quadrupedal plant-eaters protected by vertical bony plates and spikes. It was closely related to Stegosaurus and was similar to it in having two rows of, possibly alternating, plates on its back and four spikes on its tail end. The plates on its back were perhaps not as tall, but were longer.
An intimidating array of spikes covers the entire upper side of the body of the thorny devil. These thorny scales also help to defend it from predators. Camouflage and deception may also be used to evade predation. This lizard's unusual gait involves freezing and rocking as it moves about slowly in search of food, water, and mates. [2]
