What is characteristic of Saurischians?
nitrogen and oxygen
Which term is given to lizard-hipped dinosaurs?
Saurischians
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.
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.
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.
What is the difference between the Saurischian dinosaur and Orniyhischian dinosaur?
Ornitischia and Saurischia are the two taxonomic orders that comprise the superorder Dinosauria. The evolutionary split between them is the oldest and most basic division between dinosaurs. All dinosaurs are either one or the other. The most obvious differences are:The Ornitischians are named after their birdlike hips, that is, their hips resemble those of a bird in structure (an often four-pronged pelvis with the pubis pointed backward). The Saurischians on the other hand are "lizard hipped", that is, their hips resemble those of a reptile such as a lizard (a three-pronged pelvis with the pubis pointed forward). Note that the birds themselves arose from within the "lizard hipped" dinosaurs (making the names rather counter intuitive in retrospect), they evolved their bird hips separately. All known Ornitischiansalso had beaks on the front of their snouts, whereas the Saurischians did not have beaks ancestrally (though some later evolved beaks for their own purposes). All known derived Ornitischians were herbivorous, though it's possible that some early forms were omnivorous. All known carnivorous dinosaurs belong to the suborder Theropoda, and therefore Saurischia. Finally, Ornitischia are now extinct, but because modern birds are members of Theropoda, the order Saurischia persists to this day.
