Coelophysis is a theropod dinosaur; belonging in a group called Coelophysidae.There are two main groups of dinosaur, saurischian and ornithischians.Theropods are a type of saurischian dinosaur.
A saurischian is a "lizard hipped" dinosaur, and all theropods and sauropods are saurischians. Spinosaurus was a theropod, and was thus a saurischian.
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.

lizard-hipped
Okay.Ornothischian dinousaurs had bird-like hips - that is, both the ischium and pubis pointed backwards, like birds hips do. These dinosaurs were smaller herbivores.Saurischian dinosaurs had lizard-like hips - the pubis pointed forwards, and the ischium pointed backwards. All theropods and some very large herbivores had these hips.Ironically, birds evolved from the lizard-hipped dinosaurs, not the bird-hipped ones.
Something special about an Allosaurus dinosaur is that it has huge sharp teeth unlike other dinosaurs.
Most dinosaurs were reptiles and a brachiosaurus is one too so yes.
Dinosaurs don't roar to scare each other, nor do they do it to speak. They just roar to protect themselves. That's their characteristic. Just like us, they are also unique in different ways. Maybe Dinosaur's are also wondering, why do we bathe?
Caudipteryx belonged to the Saurischia ("lizard hipped"). But remember: so do birds. Birds have their pubes pointing backwards, just like the Ornithischia ("bird hipped") but they weren't onithischians themselves. So you can be a saurischian whatever the position of your pubes. As it happened Caudipteryx had forward pointing pubes, as typical for Saurischia - but it is not a decisive feature.
