It’s known that “the period is marked by some fairly impressive geological changes”. (https://www.newdinosaurs.com/the-silurian-period/) After all the continents would make their way around and stick together they would form a new groundwork.     The position of the continents during this period was low because the sea levels were rising. During the Silurian era, our region was a smaller continent of Laurentia. Laurantia was straddled in the equator. North America wasn’t located where it is now because of the different climate change that affected the movement of glaciers. The Silurian period involved a bunch of glacier movements that caused sea levels to relinquish very steeply.     The Silurian era brought a lot of life into the earth. Fish became popular, but not only that. A similar reptile like the alligator was discovered. It was known as Erypos and was the earliest land-walking reptile. The Eryops was found in Texas and its name means “drawn-out face”. An Eryops weighted about 200 pounds and had bulky legs. This reptile was very slow but that didn’t stop it from being fierce and attack predators.     A common sea creature was the creepy-crawlie , but it also appeared in the land. Creepy-crawlies measured at least a few centimeters long. They are in the family of centipedes and forebears of spiders. A creepy-crawlie is small so it has an advantage of being a flightless creature. They are found in small areas all around the planet like the ocean.    Plants also developed during this period. They started to develop by evolving stems, which would help them stand up straight. A plant would get the nutrients and what it needs it by the tubular. The most common plants were seaweed, vascular, and moss. During this time leaves weren’t very popular. You could find vascular plants anywhere at that time period and even now.    The Silurian Era came to an extinction during the hirnantion age. What’s important about this era is that it bad two ending periods. At first life during this period was mainly of the sea so it involved sea animals to come to an intuition. 85% of sea life was demolished. All of the seas were covered up by ice glaciers. The ice sheet in the Southern Hemisphere which caused climate change and a fall in sea level. What came after the Silurian era was the “Devonian period” (https://www.britannica.com/science/Silurian-Period).
