Dinosaurs are cute (pub November 1st, 2024)
Race on Wednesday, October 30.
I think that Gray Heron likes to greet me, a week ago he appeared to me once, today, during my 15 km run, she appeared twice. Well, the first time the sun wasn't up yet, I just hear her.
But with that, my wander began.
There is a discussion about whether Dinosaurs were homeothermic, I believe that at least one group, the pteropods (in this group are tyrannosaurs, velociraptors, among many others) were. Why do I think so? Because they developed a magnificent thermal insulator on their skin, like the hair of mammals, but more effective: feathers.
The feathers were a great success, And not only as insulation; They began to be used for other things, for example, as a display to “get a girlfriend.” If it is one of the most common uses of feathers in today's birds, why not then?
Well, here it is not like the story of the chicken and the egg: here, clearly, feathers appeared first and much, much later, flying dinosaurs, avian dinosaurs.
Well, about 65 million years ago a rock hit the earth, a big rock, about 10 km in diameter, traveling through space at a speed of more than 36,000 km/h until it collided with the earth.
The impact must have had the force of more than 16 million atomic bombs, like that of Hiroshima. With this, the great extinction of the Cretaceous. Some estimates even mention that 75% of species disappeared.
Among them the dinosaurs, well, not all, the avian dinosaurs remained, now we call them birds.
Those beautiful animals are everywhere. We love to see them. There are everything from large flying birds, such as the traveling albatross, which can have a wingspan of up to four meters, to tiny hummingbirds, masters of acrobatic flight, which measure just a few centimeters. But they have not only populated the heavens; We find them in arid systems in Africa running at high speeds: ostriches. But there are also the penguins, masters of life in the sea, although they still require leaving the sea to lay their eggs and care for their young while they become able to swim.
Dinosaurs are pretty...
Today the pool season ended, at noon I went in up to my belly button to comply with the tradition that the last pool day is the first of November, I could have gone in more, but... WHAT THE NEED?
