Which term is given to the lizard-hipped dinosaurs?
Saurischians.
Had a hip structure similar to birds?
Ornithischians with a hip structure similar to that of present day birds.
What is characteristic of Saurischians?
Saurischians are a group of dinosaurs characterized by their lizard-like hip structure, where the pubis bone points forward. This group includes the theropods, which are the bipedal carnivorous dinosaurs like Tyrannosaurus rex, as well as the sauropodomorphs, which are the long-necked herbivorous dinosaurs like Brachiosaurus.
Is a spinosaurus sauischian?
A saurischian is a "lizard hipped" dinosaur, and all theropods and sauropods are saurischians. Spinosaurus was a theropod, and was thus a saurischian.
What were the main types of dinosaurs?
Dinosaurs are divided into two main groups based on their hip structure: Saurischians and Ornithiscians. Saurischia means "lizard hipped" and Ornithischia means "bird hipped". Saurischian hips had the pubis pointing forward and the ischium pointing backward. All the carnivorous dinosaurs (the theropods) and sauropods were saurischians. Ornithischian hips had the pubis pointing backward and parallel to the ischium. They include all the other dinosaur groups such as the ceratopsians and the ornithopods. Ironically, birds do not descend from this type of dinosaur. Instead, they are descended from the theropods, who were saurischians.
Is a deinonychus a saurischian or a a ornithischian?
Troodon is a saurischian. Saurischians include the theropoda (animals like Troodon, Tyrannosaurus, Allosaurus, Therizinosaurus and Birds) and the sauropodomorpha (animals like Plateosaurus, Diplodicus and Brachiosaurus.) Ornithischians inlcude Triceratops, Stegosaurus, Ankylosaurus, Pachycephalosaurus and Parasaurolophus.

What are the types of dinosaurs?
There are two main groups of dinosaurs. They are the bird hipped (ornithischians) and the lizard hipped (saurischian) dinosaurs. Saurischians are divided into the theropods and the sauropodomorphs. Ornithischians are divided into the Cerapoda, Heterodontosaurids, Lesothosauridae, Pisanosauridae, and Thyreophora.t-rex, ,ankylosaurus, anchisaurus, allosaurus, anchsaurus, apotosaurus, brontosaurus,brachiosaurus, ceolosaurus, corythosaurus and much more!
Two major groups of dinosaurs in the Jurassic period?
The two orders of the Superorder Dinosauria are Saurischia and Ornithischia, meaning the lizard-like pelvic girdle and the bird-like pelvic girdle. The classification is a little strange in that the birds are almost certainly descended from the Saurischia.
What are the 2 major groups of dinosaurs?
The two major groups of dinosaurs are the saurischians and ornithischians. Saurischian dinosaurs include theropods like T. rex and sauropods like Brachiosaurus, characterized by their hip structure. Ornithischian dinosaurs include species like Triceratops and Stegosaurus, known for their distinctive beaks and herbivorous diets.
How many different groups of dinosaurs are there?
It depends on what size "group" one is talking about. There were two big groups, the Ornithischians, whose members had hips like those of modern birds, and the Saurischians, whose hips were more lived those of lizards. Within these two groups, there were smaller, but still pretty populous, groups of Theropods, Sauromorphopods, Stegosaurs, Ankylosaurs, Ceratopsians, Hadrosaurs, Pachycephosaurs, Dromaeosaurs, Ornithomimi, and probably others that haven't been discovered. The smaller groups are the Genera, and these are the names you know: Apatosaurus, Tyrannosaurus, Triceratops, etc.
