Final answer:

Some of the special characteristics of stegosaurus was a large herbivorous dinosaur, known for its bird-like pelvis, bony plates along its back, and spiked tail. Despite its large size, it had a small brain.

Explanation:

The stegosaurus, part of the group 'Dinosaurs', has several special characteristics that set it apart from other members of the dinosaur kingdom. Firstly, the stegosaurus was a herbivore, feeding on plants and leaves. In addition, it was part of the Ornithischian group of dinosaurs, which are known for their extremely specialized and complex pelvis structure, which was constructed in a similar manner to the pelvis of birds. This characteristic was, however, purely coincidental, as birds did not evolve from this group, but rather from the Saurischian group.

One of the most identifiable features of the stegosaurus were its large, bony plates that were embedded in its skin along the length of its back. These served several possible purposes, including in defensive mechanisms, and possibly also in regulating its body temperature. Additionally, the stegosaurus had a unique feature towards its tail, possessing four distinct, sharp spikes, which could have been used as a potent weapon against predators.

Stegosaurus is estimated to have been a large dinosaur, approximately 9 meters long (30 feet) and about 4 meters tall (13 feet) in height. However, despite its large size, its brain was small relative to its body size, ensuing in a lower intelligence than other dinosaur species.

Final answer:

Some special characteristics of Stegosaurus include its armored plates along its back and tail, its small head with a beak-like mouth, and the distinctive rows of large bony plates along its back.

Explanation:

The Stegosaurus was a type of dinosaur with many unique and distinguishing characteristics. One of the most incredible aspects of the Stegosaurus is its large plates that grew from its back, providing protection and possibly playing a part in temperature regulation.

Furthermore, it had a small skull and brain relative to its body size and four spike-like appendages on its tail, known as a thagomizer, which it presumably used for defense.

Stegosaurus was a part of the group Ornithischia 'bird-hipped' dinosaurs but contrary to what the name might suggest, birds actually evolved from the Saurischia 'lizard-hipped' lineage and not Ornithischia. The stegosaurus, like all dinosaurs, was a member of the larger group called Archosaurs, which also includes birds and crocodiles.
