Special volume… A History of Extinction

#1 on Amazon Japan!
400,000 copies sold in just 8 months since publication!
The book that sparked a boom in extinct animals in Japan!
This book is another museum of natural history.
- Lee Jeong-mo (Director of Seoul Science Museum)

“Was there really such an animal?”
It introduces 70 species of extinct animals in the most interesting and fascinating way in the world.
I hope you remember this!

When we think of extinct animals, dinosaurs usually come to mind.
Besides dinosaurs, how many extinct animals do we know about? Perhaps the dodo from Alice in Wonderland is the only one we know about? It's hard to become familiar with extinct animals because we've never seen them before.
It has a long and unfamiliar name like a dinosaur's name, so it's hard to remember.


This book introduces 60 extinct animal species and 10 animals that were thought to be extinct but did not.
Each animal has a unique character, like the old man next door, the laid-back neighborhood older brother, the cute kindergartener, or the dignified king, and the reasons for their extinction are explained in a fun way for each animal.
As I read, I was filled with a constant sense of wonder, “Are there really animals like this on Earth?”
The cheerful and friendly writing style helps to remember extinct animals.


The author of this book, Mr. Maruyama, said, “If the time when something disappeared from the Earth is called the first extinction, then the time when it was truly forgotten can be called the second extinction.
“I wanted to avoid a second extinction, so I wanted to introduce as many extinct animals as possible,” he said.

Let's meet 60 extinct animals, including Steller's sea cow, dodo, Gigantopithecus, ichthyosaur, spinosaurus, and Helicoprion, as well as 10 animals that seemed to be on the verge of extinction but survived resolutely and survived, including platypus, ptarmigan, and pygmy hippopotamus.
And how about remembering them and their stories? It would be a truly meaningful time.


Extinction and fun? Laughing and then feeling sad?
Serious food for thought following this dissonance!
An endangered animal encyclopedia that is great for both children and adults who are interested in animals.

Extinction is when a species disappears completely from the Earth.
So extinction is considered a tragic event.
When an animal becomes extinct due to human error, it is even more regrettable, regrettable, and reflective.
But is extinction truly a sad thing? 99.9% of all life on Earth has gone extinct.
The reasons for extinction are truly varied.
The Earth's environment changes to a point where no matter how hard they try, life can become extinct, such as when a volcano erupts, a meteorite falls, or it becomes extremely cold or hot, or when a competitor appears and life becomes extinct, or when human error causes life to become extinct.
This book makes you think about the Earth's environment, the history of evolution, and human error on a grand scale.
It's even better when children and adults watch it together.
This is a very good book for expanding the scope of one's thinking by discussing these kinds of thoughts together.


99.9% of all living things are extinct.

Humans will also become extinct someday.
A chance to seriously think about extinction!

Humans are no exception and will eventually become extinct.
If we are to survive any longer, we must learn to survive.
Lee Jeong-mo, director of the Seoul Metropolitan Science Museum, said this in his letter of recommendation:

We have to survive no matter what.
To do that, we must learn about ‘extinction.’
We need to know how other life became extinct.
That way, we can avoid and delay our extinction.
That's why we learn history and why we go to natural history museums.
This book is another museum of natural history.
I learned a lot from this book.
The only sure way to avoid extinction is to live in harmony with other living beings.
The reason we must care for nature is, above all, for our survival.
- Among [recommended words] -

This book provides an opportunity to seriously consider extinction rather than dismiss it as someone else's problem.
You can take the time to delve deeper into why that animal became extinct, or to think about how we can coexist with other creatures, and why and how we should care for the Earth.


A time of growth for children to become interested in animals!

Among the extinct animals, some only have partial fossils found, so it's fun to imagine what kind of animal they were.
That's why extinct animals, including dinosaurs, are so fascinating to children.
Most of the extinct animals featured in this book are imagined by researchers by fitting together clues they have discovered so far, like a puzzle, to imagine what the animals looked like and why they became extinct.
The longer an animal has been extinct, the fewer clues there are, which often leads to conflicting opinions among researchers.
As you read this book, I encourage you to look at the world and its animals from a different perspective.
Readers may also come up with new hypotheses about the reasons for the extinction of unknown fossils.
Free imagination is the driving force behind the advancement of science and will be a time for children to grow.
