Time: The Paleozoic, Ordovician Period

My journal entry began when I started learning about the eras of geologic time like the Paleozoic, Mesozoic, and Cenozoic eras. Although the various time periods were all very interesting, I found the Paleozoic era to be the most fascinating.'Paleo' means ancient or way early times in Greek and therefore Paleozoic means ancient life. This era was divided into six major parts. These parts are named the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian periods. The Ordovician period lasted till 45 million years. It began 488.3 million years ago and it ended 443.7 million years ago. The early Paleozoic era started when the oceans overwhelmed the low-lying insides of the landmasses. The ancient Paleozoic climates were gentle.
Second off, the Mesozoic era indicates the middle life. 'Meso' means 'middle'. It had three geologic time periods called the Triassic, Jurassic, and Cretaceous periods. The Mesozoic was a period of shifting in the historical setting of life and in the development of the earth. The vertebrates of this period were commanded by reptiles, particularly the dinosaurs. Finally, the Cenozoic era is the current life where we live right now. 'Ceno' means current or recent. It started even before 65 million years ago. Cenozoic rocks cover a significant part of the earth's surface, since they are the latest materials kept and have had less time to dissolve away. An Atlantic Ocean kept opening amid the Cenozoic era, and the development of tectonic plates made the design of today's mainland. During this era, angiosperms turned into the most dominant plants within the Cenozoic era. Warm blooded animals and winged creatures developed quickly. In the end, primates showed up in the late tertiary and quaternary time.

After learning about all of the eras in Mrs.
Laurella amazing class, I decided to hop in my time machine and go back 540 million years ago to explore the major events of the Paleozoic era. Once I reached the Paleozoic era, I looked around and saw all of the water. Eventually, I went to find the trilobites to get a sample of them so I could prove heir existence. Trilobites are fossil gatherings of terminated marine arthropods that shape the class Trilobita. Trilobites shape one of the soonest known groups of Arthropods. Arthropods are described as Crabs, lobsters, arachnids, centipedes, and millipedes—these animals all fit in with the phylum Arthropoda, the best gatherings of creatures on Earth. Then I was continuing my journey to search in of Paleozoic animals. Afterwards, I was walking and suddenly, my footsteps stopped on the hard layer. I thought it would be rocks. But then I thought again that I should just check that what type of rock it is. It was under the ground. So I tried to take it out. My robot was helping me too. I made the robot for taking samples, pictures, and videos. So, he tried to help me. And suddenly, I was so shocked. I was dying. That's how shocked I was, and guess what I found, I found a huge fossil of Permian. Permian is a Paleozoic animal that got extinct before 244 million years ago. Later Paleozoic oceans were ruled by crinoid and blastoid echinoderms, articulate brachiopods, graptolites, and organize and rugose corals. Before the end of the
Ordovician, life was no more kept to the oceans. Plants had started to colonize the land, nearly followed in the Silurian by spineless creatures, and in the Late Devonian by vertebrates. Within this period, the region north of the tropics was completely sea, and the greater part of the world's property was gathered into the southern supercontinent Gondwana. It was pretty good time. That's what I found for Ordovician period.

after so much walking, I was so hungry and and I wanted to drink some water. I finally got idea for eating. So I could eat fish for my lunch and dinner. I thought about drinking a salt water after purifying it. So I took an handkerchief and put my water bottle under the handkerchief, so when I pour water into handkerchief, it goes in the water bottle. Then I did that. I got some pure mineral water by doing that. Then I wanted to live there for one night. I got some woods from that land and I found two stones that if we splash stones with each other, it sparkles. So I got some fire on because it was so cold, and I was searching for place where I can sleep. I found that too. Then I needed a tent and it was good thing that I bought all the things that I needed for building a tent. After building it, I was so tired. So I ate a yummy fish for a dinner and I passed out because I was so tired. Then I waked up in the morning to continue my journey. Then I wanted to find more about climates of Paleozoic era, so I was moving forward and forward. I found out that the proceeded with revamp of the landmasses and their encompassing oceans profoundly affected the atmospheres of every Paleozoic period. Amid the Permian, atmospheres in the Northern Hemisphere got to be hotter and drier and the coal-swamp verdures offered route to the conifers and different gymnosperms. Glaciers shaped 430 million years prior. They may just kept going one or a couple of million years.
Amid this time, ice secured the northern piece of Africa, which was situated over the South Pole. In ancient times, the mainlands were far separated, yet moving tectonic plates made landmasses to move together into a vast landmass named Pangea. That all were major events. Then by time machine, I came back into my real life for telling you that this is all I found when I went back to Paleozoic era for my awesome and amazing journey. And thank you for letting me go back to different era because less people gets to go to new world. I liked more about this trip that I saw so many different types of creatures. And I found a fossils of the animals who lived during Precambrian time. I collected those samples. I saw many amphibians, and they were really cool. But some creatures were so dangerous because they were poisonous and we could die from it, and some were so huge that we had to look so up. Moreover, I tried to learn more and more stuff about the Paleozoic
era.
