What does the name Tyrannosaurus rex translate to?

• A. Giant Predatory Bird
• B. Ruler of the Forest
• C. Tyrant Lizard King
• D. King of Giants

Answer: (C)

The meaning comes from how the name is built from Greek and Latin roots. Tyranno- comes from Greek tyrannos meaning tyrant, -sauros comes from Greek sauros meaning lizard, and rex is Latin for king. Put together, Tyrannosaurus rex means “tyrant lizard king.” That’s why this option best captures the exact roots of the name. The other choices reflect different ideas (bird, forest, giants) that don’t match the Greek and Latin roots in the name.
