Imagine you found a new partial dinosaur skeleton, and you worked with a paleoartist to create the skeletal drawing of it shown below:Is your dinosaur a member of Ornithischia or Saurischia? What synapomorphy(s) lead you to this conclusion? Is your dinosaur a member of the clade Ornithopoda, Thyreophora, Marginocephalia, or Sauropodomorpha? What synapomorphy(s) lead you to this conclusion? The image is a silhouette of a dinosaur, featuring an overlay of visible skeletal elements. This illustration presents a reconstructed outline of the dinosaur's bony structure, suggesting its probable posture and anatomical features. Key skeletal components such as the skull, limbs, and segments of the spine are depicted in white. The scale bar at the bottom left of the image indicates a measurement of 1 meter, providing a reference for the dinosaur's size compared to its skeletal elements.The dinosaur's body shape is elongated with a prominent tail and a robust, well-developed head, characteristic of certain herbivorous species. Its limbs appear sturdy, designed to support its body mass. The depiction assists in understanding the dinosaur's possible locomotion and physical adaptation to its environment.

Dinosaurs were a group of reptiles that appeared in the Triassic period and lasted till the cretaceous. They were extinct during the cretaceous tertiary mass extinction.1) Ornithischian dinosaurs are herbivores, having their pelvic structure similar to that of the bird. The saurischian dinosaurs have their pelvic structure the same as that of the lizard. These are divided into two categories: the Sauropoda, which were herbivores, and the Apatosaurus and Diplodocus. According to the diagram shown, the dinosaur is an Ornithischian dinosaur. The reason for considering it under this category is that it has a bird like hip and beak-like predentary structure. These features are the characteristic of Ornithischian dinosaurs. 2) Ornithopoda is the group of Ornithischian dinosaurs that were plant-eaters. They are characterized by three feet. This can be seen in this figure, so this dinosaur belongs to clade Ornithopoda.The figure shown above represents the dinosaur belonging to the Ornithischian group which is a part of the clade Ornithopoda.
