Dinosaur Hip Groups

CONCEPTUAL

Science›Dinosaurs & Paleontology|Ages 9—11|ID: mt_yrSdVrXrsF

Classify dinosaurs into the two major groups based on hip structure: Saurischia (lizard-hipped, including theropods and sauropods) and Ornithischia (bird-hipped, including Triceratops and Stegosaurus)

Mastery Evidence

Name the two major dinosaur groups: Saurischia and Ornithischia
Explain the difference is based on hip bone structure (lizard-hipped vs bird-hipped)
Correctly classify at least two dinosaurs into each group (e.g. T. rex = Saurischia, Triceratops = Ornithischia)

Assessment Prompt

“Can [child] explain that scientists divide dinosaurs into two big groups based on their hip bones — and tell you which group includes T. rex?”
