Fun Dinosaur Quiz Collection for Kids and Adults

30 years

The lifespan of Tyrannosaurus is said to be about 30 years. What do you think—was that surprisingly long, or short? For reference, small theropods are thought to have lived 3–4 years, while large theropods lived around 50 years. Fossils have growth lines, and it seems that’s how these estimates are determined.

reptile

Because many dinosaurs are large-bodied, we tend to assume they might be mammals, but they’re actually reptiles. In fact, they’re related to lizards! The size is completely different, of course, but the long tails and overall shape do seem similar.

30cm

A Tyrannosaurus measured about 13 meters in total length. It makes you wonder how big the teeth of such a large dinosaur were, doesn’t it? The longest ones are said to be as much as 30 centimeters. What you can see is only a small portion of the tooth. It’s also thought that the teeth were covered by lips to protect them from damage.

Stegosaurus

Stegosaurus is the most famous dinosaur among the stegosaurs! A defining feature of stegosaurs is the series of bony plates along the back, like those of Stegosaurus. These are also called scutes (or plates), and all stegosaurs are said to share them. Another characteristic of stegosaurs is their small brains.

Thermoregulation

This plate is a bone called a dermal plate, and research has shown that many blood vessels ran through it. It’s thought that the animal may have regulated its body temperature by cooling or warming the blood carried to the plates with the outside air. By the way, I’ve heard that Godzilla’s dorsal spikes were inspired by this Stegosaurus.
