The following is a simplified classification of dinosaur families. A more detailed version can be found at List of dinosaur classifications.

Assemblage of Tetanuran theropods: Torvosaurus left above, Eustreptospondylus left below, Piatnitzkysaurus in cental position, Megalosaurus right below, Afrovenator right above, and Cryolophosaurus behind it
Various ornithopod dinosaurs and one heterodontosaurid. Far left: Camptosaurus, left: Iguanodon, center background: Shantungosaurus, center foreground: Dryosaurus, right: Corythosaurus, far right (small): Heterodontosaurus, far right (large) Tenontosaurus.
  • Dinosauria
  • Sauropodomorphs (quadrupedal herbivores with small heads and long necks and tails, and elephant-like bodies)
  • "Prosauropods" (early relatives of sauropods; small to quite large; some possibly omnivorous; bipeds and quadrupeds)
  • Sauropods (very large, usually over 15 meters long [49 ft])
  • Diplodocoids (skulls and tails elongated; teeth typically narrow and pencil-like)
  • Macronarians (boxy skulls; spoon-shaped or pencil-shaped teeth)
  • Brachiosaurids (very long necks; forelimbs longer than hindlimbs)
  • Titanosaurians (diverse; stocky, with wide hips; most common in the Late Cretaceous of southern continents)
  • Ornithopods (diverse, from meter- or yard-scale bipeds to 12 meter (39 ft) animals that could moves as both bipeds and quadrupeds, evolved a method of chewing using skull flexibility and large numbers of teeth)
  • Pachycephalosaurians ("bone-heads", bipeds with domed or knobby growth on skulls)
  • Ceratopsians (dinosaurs with horns and frills, although most early forms had only the beginnings of these features)
