Introduction of Research
There are many extinct organisms with unique characteristics different from extant ones, as well as unique lifestyles. By examining the meaning of these fossils in terms of biology, we may be able to answer questions such as "How did innovations in forms and habits occur?" and "Why did they go extinct?"
However, we must have fossils in our hands before considering these questions. In other words, we must first go to the field to collect fossils. Furthermore, if we collect fossils ourselves, we may have the opportunity to see why the organism was fossilized. Knowing "how it died" can give us a hint about "how it lived," and only collectors have access to this information.
On the other hand, fossils can provide us with information beyond biology because they record history after being buried in sediments. Collectors can freely choose how to analyze them and extract information, making this aspect of paleontology fascinating.
There are many fossils waiting to be discovered, especially with regards to fossil plants. I am committed to doing my best to uncover these hidden treasures for the world to see!

Academic degree | Ph.D. |
Self Introduction | I was born in Aichi Prefecture. I collected fossils for the first time when I was five years old. Since then, I am always collecting fossils. Lately, I've been listening to "Yorushika" which was recommended by my son. Their music takes me back to a time when my research life wasn't going well. My favorite fish is red seabream and Japanese whiting. |
