I am learning so much about dinosaurs!

In the dinosaur family from dinosauria there are two orders: dinosaurs are either: Saurischian dinosaurs  meaning "Lizard-Hipped" or  Ornithischian meaning "Bird-Hipped". Then we have two sub orders for the "Lizard-Hipped" or Saurischia: Sauropoda (quadruped herbivore- 4 legged plant eater) and Theropoda (biped carnivore - 2 legged meat eater) is the sub-order of the velociraptor


. The three suborders of Ornithischia:


and Ornithischia is the 3 sub orders for the Bird-Hipped ,Thyreophora (armored herbivore quadruped), Maryinocephal fringed heads (plant-eater Horns or thick skull) and the Ornithopoa (meaning "bird feet plant eater) is the sub-order of the duck billed dinosaurs.
