Stegosaurus

Product Information

Stegosaurus affinis, described by Marsh in 1881, is only known from a pubis and is considered a nomen dubium. [16] It is possibly synonymous with S. armatus.

The sacro-lumbar expansion is not unique to stegosaurs, nor even ornithischians. It is also present in birds. In their case, it contains what is called the glycogen body, a structure whose function is not definitely known, but which is postulated to facilitate the supply of glycogen to the animal's nervous system. [97] It also may function as a balance organ, or reservoir of compounds to support the nervous system.

PMID 26466098.Stegosaurus madagascariensis from Madagascar is known solely from teeth and was described by Piveteau in 1926. The teeth were variously attributed to a stegosaur, the theropod Majungasaurus, [63] a hadrosaur or even a crocodylian, but is now considered a possible ankylosaur.

Change the colors for a more realistic look or choose a favorite color! The most recognizable features of Stegosaurus are its dermal plates, which consisted of between 17 and 22 separate plates and flat spines. [13] These were highly modified osteoderms (bony-cored scales), similar to those seen in crocodiles and many lizards today. They were not directly attached to the animal's skeleton, instead arising from the skin. The largest plates were found over the hips and could measure over 60cm (24in) wide and 60cm (24in) tall.

This dino was made to look more an action figure where a pipe cleaner skeleton was added so he can move his legs. Although Stegosaurus is undoubtedly now considered to have been quadrupedal, some discussion has occurred over whether it could have reared up on its hind legs, using its tail to form a tripod with its hind limbs, to browse for higher foliage. [40] This has been proposed by Bakker [59] [70] and opposed by Carpenter. [25] A study by Mallison (2010) found support for a rearing up posture in Kentrosaurus, though not for ability for the tail to act as a tripod. [71]More recently, a study of the tail spikes by McWhinney et al., which showed a high incidence of trauma-related damage, lends more weight to the position that the spikes were indeed used in combat. This study showed that 9.8% of Stegosaurus specimens examined had injuries to their tail spikes. [85] Additional support for this idea was a punctured tail vertebra of an Allosaurus into which a tail spike fits perfectly. The damage shows that the spike entered at an angle from below and displaced a piece of the process upward, remodeled bone on the underside of the process shows that an infection developed.

S2CID 53328847. An amigurumi dinosaur is similar to a crocheted dinosaur, but it specifically refers to the process of creating 3D toys. Crochet uses a variety of techniques, whereas amigurumi is almost always done in the round, creating spheres that are then stuffed to form the limbs of these adorable little dinosaurs. Stegosaurus stenops had four dermal spikes, each about 60–90 centimetres (2–3 ft) long. Discoveries of articulated stegosaur armour show that, at least in some species, these spikes protruded horizontally from the tail, not vertically as is often depicted. Initially, Marsh described S. armatus as having eight spikes in its tail, unlike S. stenops. However, recent research re-examined this and concluded this species also had four.
