Theropods vs sauropods vs ornithischians

What you’ll practice

You’ll train your eye for the defining features of theropods, sauropods, and ornithischians—especially hips, posture, feeding adaptations, and overall body shape. Questions range from quick ID checks to trickier comparisons, keeping the difficulty mixed but fair.

Because every item uses 4 options and there’s no timer, you can slow down and reason from clues instead of guessing under pressure.

Common pitfalls to avoid

Many players mix up “lizard-hipped” vs “bird-hipped” labels, or assume diet alone decides the group. Another frequent slip is treating size as a shortcut (not all huge dinosaurs are sauropods, and not all two-legged dinosaurs are theropods).

• Don’t rely only on diet; use hips, stance, and skull/neck/tail clues too
• Watch for look-alike traits (horns, plates, crests) that can mislead classification
• Remember: theropods are mostly bipedal; sauropods are classic long-necked quadrupeds
• Ornithischians often show specialized chewing and beaks, but details vary
• Use elimination: rule out two options first, then choose between the closest pair

Choosing length and difficulty

Set your preferred question count before you start if you want a quick run or a longer study session; the full quiz contains 103 questions. Difficulty is balanced by mixing straightforward group traits with more nuanced items, so beginners can learn while experienced players still get challenged.
