Dinosaurs were born more than 200 million years ago and once thrived and lived on Earth.

Today, we can only see dinosaurs through fossils and other remains, but imagining that dinosaurs might have lived right where we are now stirs a sense of ancient romance, doesn’t it?

Some of you may have children who loved dinosaurs when they were young, or grandchildren who are fascinated by them.

So this time, we’re introducing a “Dinosaur Quiz for Older Adults.”

We can’t see dinosaurs today, so they don’t feel very familiar, and answering questions about them can require specialized knowledge.

That’s why this quiz features easy-to-answer multiple-choice questions with three options, designed for older adults.

Please feel free to use it for quiz activities at senior facilities and similar settings.

[For Seniors] Fun and Easy! Dinosaur Multiple-Choice Quiz (Questions 11–20)

What does the “-don” in names like Iguanodon and Pteranodon mean?

corner; angle; horn (depends on context)
tooth
tail

See the answer

tooth

“-don” comes from the Greek word “odōn,” which means “tooth.” Iguanodon thus means “iguana tooth.” When Iguanodon fossils were discovered, they were named because the teeth resembled those of an iguana. By the way, although the name is similar to the reptile “iguana,” they are not actually related.

What is the name of the smallest dinosaur in the world, whose name means “very small thief”?

Triceratops
Microraptor
Stegosaurus

See the answer

Microraptor

Because its name includes “micro,” it conjures an image of something small, doesn’t it? “Raptor” means “thief.” Microraptor was about 50 centimeters long and weighed around 3 kilograms. Its entire body was covered in feathers, and it even had feathers on its hind legs. While modern birds don’t have feathers on their hind legs, Microraptor was a dinosaur closely related to birds. Though its small, cute appearance comes to mind, it was apparently carnivorous.

Currently, the largest egg in the world is the ostrich egg, which is 16 centimeters. During the age of the dinosaurs, how many centimeters was the largest egg?

20 centimeters
60 centimeters
100 centimeters

During fossil excavations, many dinosaur eggs have been discovered. Their sizes vary widely, from 4.5 centimeters to 60 centimeters. Even though some dinosaurs were enormous—stretching dozens of meters—their eggs are notably on the smaller side. It’s said that dinosaur eggs had tiny pores so the embryo could breathe, and their shells were just the right hardness for the babies to break out on their own.

Some herbivorous dinosaurs put something into their stomachs to grind up the plants they ate. What was that “something?”

seashell
stone
bone

Herbivorous dinosaurs ate fibrous plants. Their teeth were shaped to grind leaves, but sometimes that grinding was not sufficient. To aid digestion, they swallowed stones to further break down the plant matter in their stomachs. These ingested stones are called gastroliths, and the behavior is also observed today in animals such as crocodiles and herbivorous birds.
