On January, I got injured my waist and got flu, so I couldn't do training enough. Tody, I feel get better. I try to do training little bit harder today.

I return from night shift right now. Our night shift is over twelve hour for one day, so I'm sleepy. However, I will go to Gym to do short training. I need to do sports to keep my health.
Zuul crurivastator
From March 14th in National Museum of Nature and Science, The Dinosaur EXPO 2023 has been opened. This event is until June 18th, so you should go there to see it if you’ve not done it. I entered it in opening time, and make fuller better use of it including permanent exhibition until closing time.
There are many interesting exhibitions. However, the starring role of this expo is “Zuul crurivastator”, one of the Ankylosauria. Ankylosauria is a group of Ornithischia, a big group of Dinosaurs. Speaking of Dinosaurs, many people images Tyrannosaurus rex, and Theropoda, which is a dinosaurs’ group T.rex belongs. Actually, there are 2 T. rex on this expo. However, the main is Zuul.
Ankylosauria is a kind of Thyreophora, which is including Stegosauria like Stegosaurus. All of them are herbivory, and they have unique apparels on their backs. Stegosauria have bony plates or spikes. The other hand, Ankylosauria have armor, which is bony skin for defense. Ankylosauria also have a bony body like a bat for the battle against carnivorous dinosaurs or other Ankylosauria.
Their body was covered by bony skin, so there are many fossils which keeps the appearance they live. Especially, Zuul crurivastator is famous for marvelous state of preservation. That is the biggest viewpoint of this expo.
Cherry blossom
I’ve been able to write this blog so long time, so I try to write a series of my concern. The theme is “natural life forms”. It is including not only the current one but also the ancient one.
As the first issue, because of cherry blossom appreciation season, which is already over a little bit, I write about cherry blossom.
In Japan, many people image “Somei-yoshino” as a cherry blossom. “Somei-yoshino” is a breed variety of Japanese cultivated cherry blossoms, whose mother is “Edo-higan” and father is “Oshima-zakura”. The scientific name is Cerasus × yedoensis (Matsum.) Masam. et Suzuki ‘Somei-yoshino’. It is so long! The reason is “Somei-yoshino” is a cultivated plant by artificial crossing, not a natural plant.
There are 11 species of wild cherry blossom (subg. Cerasus):
Oshima-zakura (Cerasus speciosa, P. lannesiana var. speciosa)
Yama-zakura (Cerasus jamasakura)
Ooyama-zakura (Cerasus sargentii)
Kasumi-zakura (Cerasus laveilleana, P. verecunda)
Edo-higan (Cerasus spachiana, Cerasus itosakura, P. pendula f.ascendens, P. subhirtella var. ascendens)
Mame-zakura (Cerasus incisa)
Takane-zakura (Cerasus nipponica)
Choji-zakura (Cerasus apetala)
Miyama-zakura (Cerasus maximowiczii)
Kumano-zakura (Cerasus kumanoensis)
Kanhi-zakura (Cerasus campanulata)
（Resouce is Wikipedia.）
“Somei-yoshino” is a hybrid of “Oshima-zakura” and “Edo-higan”.
“Somei-yoshino” are not spread by the seeds. They are spread by cottage, so they are clones! Certainly, many garden plants glow from cuttings. Speaking of “Somei-yoshino”, they bust out by warming in spring. The reason is also that they are clone.
However, they are vulnerable to the diseases and the bugs. Because they are planted concentratively in parks, there are high risk of the invasion of them. So, the planting with other breeds was increasing recently. If you go cherry-blossom viewing, try to watch other Sakura-breeds. You may enjoy Sakura more deeply.
My wife maybe start triathlon
I have done triathlon for 7 years. And recently, my wife said she want to challenge triathlon, too.
She already be able to swim and run, but now she doesn't ride bicycle. So, now I research the bicycle for her. Ofcourse, we use a road racer for triathlon race. My wife is afraid of sports' cycle becouse of its hi-speed, because she is beginner of sports bike. So, now I consider the security of the bicycle.
I hope I can find a good road bike for her.
Start to use Hatena blog app.
I found official hatena blog app.
I couldn't update my blog because I couldn't use time for it. However, I 'd like to write this blog for practicing English.
I tried to write this hatena diary using unofficial blog app, but it is difficult to use for me.
Now I try the official app. I feel it is more comfortable than I used before. I hope I can continue to write this blog.
